If you’re old enough, you may be able to remember when Heavyhands was an honest to god craze. About twenty five or thirty years ago, people started showing up to run with these little hand weights that had handles attached to them so that were easier to hold than, say, dumbbells.

The idea was that you would swing the weights while you walked or run, and you would get twice the workout in the same amount of time. The idea was developed and popularized by Leonard Schwartz, a middle aged doctor who was looking for something other than running to get his cardio in, and it was a good idea.

Of course, it didn’t work. The craze came and went, and for the most part, the little Heavyhands weight found a resting place in closets, never to be used again. This was not actually Dr.Schwartz’s fault, to be fair, and there is a lot of merit in what he had to say.

The problem was is that Heavyhands were supposed to give you a vigorous arm workout, but this required actually swing the weights while you ran or walked, keeping a steady pace. This is what you were supposed to do, but it isn’t what most people actually did. Instead, they just carried the weights as they ran.

Now, if the Heavyhands weight were fifty-pound beasts, this might have worked, but since they only weighed a pound or two, the effect was negligible and people soon quit using them. Much like the Atkins diet, most of the people doing Heavyhands had never actually read the book.

This is a shame, because Schwartz was on to something. He did meticulous research into how pumping hand weight affected oxygen uptake and energy burn, and his personal results were impressive.

The highest VO2 maxes in the world tend to be held by rowers and cross-country skiers, both of whom use all their limbs for their sport. This led Schwartz to reason, correctly, that using the arms would allow you to build your cardio system in a whole new way.

This is good stuff for the serious runner. This allows you to continue to build your cardiovascular endurance without endless speed work or infinitely increasing mileage. Instead, with the hand weights correctly used, you can radically improve your ability to get oxygen into your system, which will in turn radically improve your running.

What you probably shouldn’t do is run with the Heavyhands weights. If you do, and you’re a competitive runner, you’re going to mess up your biomechanics for the actual races, which is not something that anyone wants.

Instead, replace some of your mileage for at least six weeks or so with Heavyhands walking at as brisk a pace as you can manage, while swinging the weights to forehead height or so. This is going to be a lot harder than it sounds, but it can add a lot wind to your lungs and a lot of speed to your runs faster than you can say Heavyhands.

Dan Gable, legendary Olympic wrestler and coach, once said, “If something is important, do it every day. If it’s not important, don’t do it.” There’s a lot of truth to that, because a lot of what we do, even with running, involves honing skills that only come with hours of practice.

In fact, it’s said to take ten thousand hours of practice to truly be considered a master at something. That’s two hours of training a day for fourteen years, which is a lot of work and dedication. But, you know, there’s something to be said for the idea of less is more. It’s actually possible to get better at running without running.

At least, for controlled periods. You can’t expect to not run for years and then suddenly come back and smash your previous records, but a short period away from pounding the pavement can actually be just the thing to bust you through a plateau. The trick is that you have to be able to do it right.

Runners notoriously have the some of the highest injury rates in athletics. While these are not generally as dramatic as Joe Theisman’s femur getting snapped like a twig by Lawrence Taylor, it is an insidious problem that will creep up on many if not most runners at some point.

The trouble is repetitive stress, where the body repeats the same action over and over and over. While practice is necessary and good, you can easily get too much of a good thing by doing the same thing all the time, every time. Think of office workers who eventually need surgery because of typing, now imagine the pounding your knees and ankles take.

Even beyond the damage repetitive stress is doing to your body, there’s also the fact of accumulated fatigue. Virtually anyone who trains to get better, which everyone who takes running even a little seriously, is going to be fatiguing their body little by little, in ways that aren’t obvious except over the long term.

The answer to all of this is to stop running. Now, obviously, you should be just sitting on the couch instead of running, although there is something to be said for the rejuvenating effects of vegging out for a week or two every year or so.

No, instead you’ll want to replace your running with another hard aerobic activity for six weeks or so every so often. The best time to do this is right after a hard race, to give your body some time to rest and recover.

Try to pick and activity that will keep your lungs and legs in shape while giving them a new stress to adapt to. Try running stairs exclusively, or taking up biking for a while. The trick is that you need to work hard.

If you do it right, you find that when you come back to running you will be able to with a lot more vigor and energy then you previously had, and you may even gain the momentum needed to hit some brand new personal records.

Running, like pretty much everything else under the sun, has its trends and phases. Nutritional advice comes in and out of fashion as scientists, trainers and seemingly everyone else in the world offers up opinions and evidence on what may be optimal for people seeking to get the most out of their running. Paleo nutrition, which is a diet designed with the idea of eating foods that only our ancient ancestors would have had access to, is the latest idea to come along, but is it one that runners should embrace?

The basic idea behind eating paleo is that we’re only ten thousand years or so removed from our Paleolithic ancestors, hence the name, and that our digestive system and metabolism have not had time to adapt to foods that were not included in the Cro Magnon diet. In other words, grains and sugars.

The theory behind the paleo diet is that we’re not adapted to these foods and that consuming them in mass quantities is detrimental to our health to greater or less degrees, resulting in what’s called the diseases of civilization: heart disease, diabetes and cancer. If we eliminate the foods that didn’t existed when our bodies evolved, then we would be healthier and fitter.

This is at odds with what a lot of runners have adopted as their mantra, which is carbs, carbs, carbs. While the paleo diet is not necessarily low carb, it’s a lot harder to eat 500 grams of carbs in green leafy vegetables than it is to chow down on bread or pasta. But is this carb focus really optimal?

The idea is that running needs energy, and energy comes from carbs. Which is true, for about 400 meters. But long distance running pulls much of its energy from your fat stores, since the amount of energy stored as glucose in your blood, which is what carbs convert to, is really pretty minimal. So runners may not need all those extra carbs anyhow.

Which doesn’t necessarily mean that paleo diet is the way to go. Some runners have tried and done extremely well. Ultramarathoner Dean Karnazes has switched to a paleo diet, and it hasn’t seemed to negatively affect his running, although he does rely mainly on fruit for his carbs.

The problem is that while the paelo diet sounds great in theory, that’s all it is right now, a theory. There is anecdotal evidence from looking at what the few remaining hunter gatherers eat and what the historical record tells us, and the idea makes logical sense, but that doesn’t men it’s true.

What is true is that the paleo diet recommends you eat meat, fruits and vegetables, eliminating processed foods and sugars, which is a healthy diet by pretty much any standard except hardcore vegans or carnivores.

Probably the worst thing you can say about fartlek training is that it kind of has a funny name, which probably still gets giggles at high schools everywhere. It’s appeal to lowbrow humor not withstanding, incorporating fartlek training is probably one of the best things you could do for your running training.

Fartlek is a Swedish word meaning speed play, and the basic idea is to intersperse periods of different running speeds into your running. This isn’t quite the same as interval work, although the basic idea is similar; you want train your muscles in new ways to increase your overall speed.

The average runner, someone who runs to keep fit and maybe does the occasional race, usually trains by doing a warmup, a run at a fairly steady pace, followed by a cooldown. This is an effective way to train up to a point, but you will reach a plateau fairly quickly where you are going to need more to increase your speed.

By incorporating the fartlek concept, you are exposing your body to new stresses to cause it to adapt, and you do this by incorporating a variety of running speeds into your run, rather than just holding a steady pace.

The word play in the translated title is actually the key to making this system work the way it’s supposed to. Think of kids who are out playing, who will walk, run and jog at seeming random intervals. This is what you are trying to emulate.

So at one session you might spend ten minutes running at a steady pace, then sprint for a minute, then walk for a minute, then sprint again, and so on. The idea is keep the shifting speeds random and unpredictable. If you feel like running fast do it,, if you don’t, walk for a while.

There are a couple of reasons this works. One of the big ones is that your body basically has two energy systems, the aerobic and the anaerobic, and fartlek training helps you train then both. A lot of runners only focus on developing their aerobic energy system, which leaves them using only part of what their bodies are capable of.

Another way that it helps is the related concept of muscle fibers. Your body has slow twitch muscle fibers, which are more endurance oriented, and fast twitch fibers, which are more power and speed oriented. If you want to maximize your speed and continue to improve, you absolutely need to make sure you develop both of them.

Of course, subjecting your body to new things is also just plain good for you. Your body is unimaginably complex, and every bit of novelty is going to cause some kind of adaptation that will work to your benefit,, even beyond the big energy systems and muscle fiber benefits.

And fartlek training is just fun. Bounding and sprinting, setting mini challenges for yourself like running a certain number of telephone poles’ distance full title before slowing down, makes even a route you’ve run a thousand times seem like a brand new world.

Injuries are the bane of any serious runner, and many not so serious runners. These can both be the acute, like a torn tendon, or chronic like stress fractures. The average runner spends a lot of money on shoes and orthotics that are designed to minimize the chance of injury and keep them running better for longer.

But what if the shoes are the problem?

That’s the question being asked by proponents of barefoot running, who believe that the altered gait that is produced by heavy, shock absorbing shoes isn’t help us avoid injuries, it’s causing them. What if everybody would be a lot better off if they ditched the shoes and started hitting the road barefoot, or something close to it?

It seems like a strange idea, but there is a lot of evidence that the barefoot folks might have a point. Shoes absolutely do change your stride, moving you from a shorter, toe first stride to a longer stride where the impact is on your heels. In fact, this change in stride was the entire point of the original Nikes, which were designed to allow a longer and theoretically faster stride.

The problem with this is that it shifts your weight from something designed to work as a natural shock absorber, the front of your foot and toes, and transfers it to something that is absolutely not designed for that kind of abused. Think about jumping up in the air; you wouldn’t land on your heels, would you? When you do this, the heavy padding we associated with modern running shoes becomes an absolutely necessity.

The idea of barefoot running being superior has been around for decades, at the very least, but the idea got a big boost in 2009 with the publication of Christopher McDougall’s best seller about the lost tribe of ultra runners, the Tarahumara, who run hundreds of miles in nothing but thin sandals made from truck tires.

McDougall, a runner himself, charts the barefoot movement in his book, and eventually overcomes his own running related injuries by using a barefoot program. All of which makes for an interesting story and great anecdotal evidence, but what does the science say about it?

Unfortunately, there haven’t been any long term controlled studies about the issue. A review of the various reports on the issue does indicate that barefoot runners suffer from significantly less chronic and acute injuries to the ankle and lower leg, as well as four percent less energy cost. So the science seems to indicate that the barefoot running group has merit, but more studies are need before conclusions are made.

Although the hardcore in the barefoot running crowd actually do run in their bare feet in all sort of conditions, most people actually use a very thin shoes with out padding to protect their feet from stones, broken glass and the other detritus of modern lift that can be hard on runner’s feet. The most popular shoes for this is weird looking foot glove called the Vibram Five finger, but other options are out there for people who want to try barefoot running with growing a set of hooves.

If you’re running, then you need to be lifting weights. The benefits of resistance training are just too big for any runner to ignore. A good weight lifting program will help prevent injury, help give you more energy, and shave time off your runs, all good stuff.  But you need to go about it in the right way, or you can end up overtrained and injured. Here’s a quick guide to getting started with resistance training.

Pick Exercises That Give The Most Bang For Your Buck

The best exercises are the ones that hit the most muscles at once. You want to spend as little time as possible in the gym while still getting the best result, and working your big muscles is the way to do it. The absolute best exercises for runners are deadlifts, squats, bench press, rows, and the shoulder press. These five exercises will work virtually every muscle in your body from your toes to your neck.

Keep Your Sets and Reps Reasonable

You absolutely do not need to spend hours in the gym doing endless sets of infinite reps. Generally speaking, three sets of five to eight reps is going to be plenty. Always try to do more reps at each work out and when you get beyond eight reps, add enough weight to take you back down to five reps. This way you continue to get stronger without having to spend your whole life in the gym.

Stop Short of Failure

On every set, you always want to leave a little in the tank for next time, so stop a rep or two short of not being able to move the weight anymore. You don’t run until you collapse, and you should lift that way either. You should try to leave a weight session with more energy than you started with.

Try Three Days a Week

Working your whole body, three days a week, works for almost everybody, so long as you’re managing your energy and recovery. If you find that you’re continually dragging during your weight workouts, or that you don’t seem to have the energy you want when you’re running, you can scale it back to twice a week and see how it suits you.

Work Through Soreness

When you first start lifting weights, you are almost certainly going to get sore. This is just one of those unavoidable facts of life. You might be tempted to wait until you’re not sire anymore to lift again. This is a common reaction, and it’s almost always a mistake. You should work through the soreness, and you’ll find that your body will adapt and stop getting sore. Soreness is not a good indicator of recovery, and for the most part, it’s something you should ignore.

Note that we’re talking about soreness and not the kind of pain you get when you’re actually injured. If you do hurt yourself, which is unlikely but still possible on a good weight lifting plan, you need to take time off and recover, just as you would with a running injury.

As a runner, I am constantly looking for ways to decrease the necessity for rest while increasing my ability to recover. Part of the reason is that I don’t want to be sore all of the time, and finding the correct training and recovery balance is important for that. The other part of the equation is that I want to recover faster so that my body can take more pain…which means I have more time to train.

I don’t like rest days…I hate them. I’m born to run and any day spent without some sort of physical activity is one in which I just don’t feel as accomplished as the days before. Sure, you could say that running might be an unhealthy addiction, but compared to other self-medications, like booze or drugs, I’m OK with my running habit.

So with that being said, I’d like to discuss 5 ways that I’ve been able to train my body to recover faster.

1. Ice baths – Most people refuse to try ice in any form. Yeah yeah…it is pretty darn cold, but once you get used to the routine you stop hating it so much. Ice packs work OK, but a cold ice bath is one of the most effective ways to reduce inflammation and speed up recovery. The trick with an ice bath is not to get the temperature to near freezing and in fact many times you don’t even need ice to reach the right temperature. Let the water run and slowly add ice until the water gets into the 40’s or low 50’s, which is plenty cold enough to reduce your core temperature and start the healing process. The first time might be tough, but you’ll get used to the feeling very quickly. After 10 seconds, you’ll be in recovery heaven.
2. Amino acids – Amino acids are the building blocks for protein, which means that your muscles need them in order to repair and rebuild. There are a few great amino supplements on the market, but any is better than none. The great thing about amino supplements is that they are fed directly to your starving muscles, which speeds recovery and will ensure that you get the most benefit from your training.
3. Recovery drink – A good recovery drink taken post-race or post-workout can help you improve recovery by leaps and bounds. Immediately after a workout, prepare a mixture of 1/4 protein and 3/4 carbohydrates. The protein will work to repair your muscles while the carbohydrates will help to restore what you lost during your workout. Your body can then focus on recovery rather than digging for energy sources.


4. NSAID’s – Motrin, Naproxin, and the rest of the NSAID crew can help to reduce inflammation, which will help your body rebuild at a quicker pace. The trick with these is not to become dependant and only use them when you need to. Natural methods are better, but when left without options or when in considerable pain, 400 mg of Motrin can do the trick.
5. Stretching – This is the lost art…most people don’t like to stretch, but it must be done. Post-workout stretching is just as important as pre-workout stretching is. When you stretch after a workout, you’ll keep your muscles from contracting and tightening up, which will help conserve energy and allow your body to feed essential nutrients to your recovering muscles. It will also increase blood flow, which helps oxygenate your legs and prevent more serious conditions.

Runners need to spend as much time thinking about recovery as they do about training. It might not be as sexy, but ensuring a speedy recovery will help you to reap as much benefit as possible from your workouts. After all, what’s the point of training if your body cannot take advantage of it?

The following is a guest post from Charlene Jaszewski, a fellow runner and resident of New York City. This is a great post about a problem that most of us deal with from time to time. Make sure to leave a comment at the end of the post.

If you’re like me (and god help you if you are), your number one problem on a run is not coming up with enough energy to complete your run, it’s keeping your mind from going crazy during the run. If you’re just running 45 minutes, it’s easy enough to keep your mind entertained with scenery on the way out and back. But once you start pushing your mileage up up and away, it becomes more important for you to keep your brain in check.  Here are some methods I use.

1. Listen to fast music.

If you listen to the iPod Nano, you can define a “Power Song” that you can pull up in those instances where you need an extra kick.

2. Do a mantra.

Mantras are words repeated during meditation to calm and control the mind. I discovered mantras during a failed attempt at a meditation practice. However, I found by accident that a speeded-up mantra DOES work while running. Obviously “OM” doesn’t work for this purpose, but the Hare Krishna one does. It goes like this:

Hare krishna hare krishna
krishna krishna hare hare
hare rama hare rama
rama rama hare hare

3. Find a rabbit

Here’s how it works. Run in an area with other folks (easy enough to do in the city where I live) – in your sights, find someone who is running ahead of you, but JUST A HAIR FASTER. He/she is your rabbit. Make it a challenge to catch up to them. If you’re feeling ballsy, you can even try to pass them, but don’t get too cocky. And don’t make it apparent that you’re chasing them or you might creep them out. Then again if you do, they will run away faster, creating an even greater challenge for you.

One recent rabbit and I did a speed/up slowdown for almost 45 minutes – I would catch up to/pass them, then when I would slow down, they would speed up/pass me. Glorious! And unless your rabbit is extraordinarily cute and you want to have a post-rabbit conversation, you don’t even need to say “thanks for being my rabbit.”

4. Cityzagging:

*Only to be undertaken by the very agile and quick, requires dense population and wide sidewalks

Part of my run home involves three long city blocks near Central Park. The sidewalks are very wide (10-15 ft) and there are pockets of people every 20 feet. While running home, it’s necessary to zig and zag between people to keep up my pace. But now instead of zigging when I have to, I CREATE zigzag situations. Like a pocket of people only five feet spread instead of ten.  It’s really fun because not only do i get the workout benefit of varying my speed, I get the mental challenge of estimating the ideal speed/trajectory to avoid plowing people over.

Running Shoes – How to Choose

I get a lot of questions about running shoe selection and what types of shoes I recommend. Well, the truth is that although there are two major factors to help you choose a good shoe, for the most part choice is an individual preference based on what feels good on your foot. It is also important to take into account your foot type and running style. If you have a high or low arch, you’ll need to make sure you pick a shoe with the proper amount of cushioning. Many experts recommend changing running shoes every 350-500 miles or 6 months and although worn in shoes often feel comfortable, for the health of your feet and ankles it is important to buy new shoes as often as you can afford to. I recommend buying a new pair every 3-4 months and breaking them in every other run or so until you have two good pairs. That way, if you wear one set of shoes out, you will have another set already broken in. It also helps to have two pairs in case they get wet or damaged somehow. In regards to running specific shoes, there are 3 major types:

• Flats - which are intended for speed on a track type surface
• Road Shoes – which are intended for regular or long distance runs on pavement, sidewalks, or tracks
• Trail Shoes – which are specifically designed to take a beating and resist water when running off-road

Although I find flats useful, I won’t be talking about them here because this site is mostly geared towards road and off-road running and regular road shoes are perfectly adequate for running on a track for intervals or other speed work.

Road Shoes

My favorite road shoes are New Balance, Asics, and Nike however many people dislike Nike running shoes and prefer Mizuno or Saucony. As I said before, much of shoe selection is personal comfort and preference. The most important part about picking out a shoe is to not buy a cheap shoe because it fits your budget at the time. You would be much better off saving up for a more expensive shoe than you would be buying a new pair of cheaper running shoes. Cheap running shoes feel good at the store, but they don’t wear well, they don’t fit good enough to prevent blisters and/or shin splints, and they cause you to run with bad form. I’ve made the mistake of buying a cheap pair of running shoes because I thought I could get away with it, but in the end I wasted $50 and never wore them again due to shin splints and bad comfort.

New Balance

One of the most popular road shoes of all time is the New Balance 768: This is a great mid-range shoe that is excellent for average training. It has plenty of support to prevent pronation and is water-resistant. It is also a great shoe for those with low arches.

Trail Shoes

Trail shoes have some very distinct features to differentiate themselves from regular road shoes. Good trail shoes with have some sort of tieless laces that zip tight so you won’t have to worry about them coming untied. Also, they are generally built with more durability, strength, and water resistant qualitites.

New Balance

New Balance has a couple of great offerings, including the MT 800 which is a bit lighter than a typical road shoe at the expense of some extra protection. However, this is a very good looking and well constructed shoe.
