Heel Slide: The Most Important Exercise You’ve Never Heard Of

If I told you that adding one exercise movement to your workout could reduce your likelihood of injuring your knee by 90% would you be interested? If so, this is your lucky day. Introducing the heel slide.

You’ve heard me talk about heel slides for some time but I’ve finally gotten around to shooting a proper instructional video. While this movement is easy to do once your understand it, the position you need to get into is subtle and requires some explanation. This movement should be done two or three times per week, either alone (as shown) or tacked on to the end of any lower-body workout.

While originally slated for P90X2 we replaced it because it requires a body length of open wall space, which is something surprisingly hard to find in many people’s homes. You also contact your heel with the wall, which could blemish your house, further complicating the scenario. We thus replaced it with a similarly-effective movement but for those of you with the space, I suggest swapping heel slides for an exercise we called Tony’s Triangle during Phase 3 or, at least, alternating between the two. I would also highly suggest adding it to whatever routine you’re currently doing.

So what’s the big deal?

All the credit for this exercise goes to Dr. Marcus Elliott and P3 because I’d never seen it before training there. I knew the importance of strengthening the gluteus medius but the movements I’d been show by various trainers and physical therapist paled in comparison. In fact, most of them allowed me to unknowingly cheat and use larger muscles to shoulder the burden of the movement, actually creating a further muscular imbalance—so essentially there we heightening the problem they were supposed to fix.

Anyway, anyone who follows sports knows that more athletes break down than ever before. It seems like society accepts this as a byproduct to becoming bigger, stronger, and faster but research has shown that to be fallacy. We are breaking down because we are unstable in our hips (and shoulders). This causes a biomechanical tracking problem that radiates through the body. Someone who lacks hip stability puts excessive force on their joints each time they move. Add enough force to the equation and breakdown occurs, usually at the weak link, our soft connective tissues. This is so prevalent that “torn ACL” is about as well understood today as “I’ve got a headache.”

As proven by Elliott and his staff, this is mostly preventable. Studies done on elite athletes have shown that instances of hip instability usually exceed 90%, meaning knee injury is a when not if scenario. Teams trained by Elliott have seen instances of non-contact knee injuries drop to virtually zero. And most of this is corrected by one thing; strengthen a small muscle called the gluteus medius.

But this is not as simple as finding the muscle and isolating it. The pelvic girdle is a complex area where muscles wrap around bones and joints and criss cross each other. When out of alignment the body reacts in a way where the larger muscles will take over the motions that should rely on smaller ones that exacerbate imbalance. When this happens we tighten up. Our posture fails, followed by our movement patterns. No amount of stretching or adjusting will fix it because the imbalance we simply pull us right back out of alignment until all the muscle are strengthened and taught to work together properly.

Granted, heel slides alone won’t fix all the imbalances along your kinetic chain (though P90X2 is designed to do just that). But adding them to your routine is a great place to start.

The One Workout Every ONE Should Do

My latest training article for DPM has launched. It’s titled The One Workout Every Climber Should Do but it’s a workout every single person should do. Although the strength you gain from it is very specifically applied to climbing it’s also vital for almost everything else you do with your upper body. So while it may not be the ONE workouts you should do, everyone will reap huge benefits from it. I could go on but I’ll quote the article instead.

Climbers aren’t the only demographic to ignore the importance of stability training. A few sports scientist friends, trying to answer the riddle as to why bigger, stronger and faster-than-ever-before athletes are also most injured in history found that most—in some cases as high as 90%--showed significant muscular imbalance. When we’re out of balance don’t move with biomechanical efficiency and our linear movements don’t “track” correctly. When this occurs an injury can happen anywhere along the body’s kinetic (movement) chain.

In populations where these imbalances have been correct they’ve seen non-contact injury rates plummet. The major areas of focus are the shoulders and hips. Pelvic (hip in the colloquial) stability can be important for climbers (and everyone) but in the need-to world of sports specific performance we’re only going to address the shoulders.

This region hosts the origin of almost every move that climbing begins with. And while it does not include the “money” area, the hands and forearms, biomechanical alignment problems will radiate to that area as well, meaning that imbalances in the scapular region can lead to elbow, wrist, or even finger problems. Even though you rarely fail on a climb because your back or shoulders were pumped, strengthening these areas properly will shift more of each climbing movement’s burden to this region’s larger muscles, thus saving your smaller hand and forearm muscles for when you actually need them. This energy savings also translates to less strain on connective tissues, reducing instances of tendon and ligament damage.

This article is the second in a series. The first is titled Should You Train?, which means should you train for climbing (it is a climbing magazine after all), but has some application across the board as well and should be worth reading, especially if you participate in a sport where you get a lot of exercise by just doing the sport.



The movement videos should be live sometime today on DPM. If they aren’t you can find them by clicking the two presented here on the You Tube icon and following the series.

Plantar Fasciitis Exercises (Video)

How To Treat (and Avoid) Plantar Fasciitis

Here’s a decent little video on what plantar fasciitis is and how to treat it in its acute phase. What it doesn’t cover is how to get rid of it or, better yet, prepare your body so that you don’t get it in the first place. Once you get it there’s no way around a fairly lengthy rehab process and it’s not all that hard to avoid. Here are a few exercises that, when done regularly, will greatly reduce the chance of you getting plantar fasciitis. When you have it, these are also your go-to movements.

A,B,Cs: I hate it when doctors prescribe this exercise as a treatment for foot injuries. Not because it’s bad but because once you have foot issues you must get more aggressive with your rehab and this tends to get prescribed the most only because it’s simple. All you do is draw the alphabet with your feet in the morning before getting out of bed. If I’m spending a lot of time on my feet—like when I’m running ultras—I’ll do the alphabet both forward and backwards, slowly. It’s a great warm-up for your feet prior to getting out of bed.

In and outs: While A,B,Cs are a great warm-up, you need to strengthen all the muscles of your foot and ankel so that it doesn’t collapse, which is probably how you got PF in the first place. This exercise can be done anytime and anywhere. Sit with your legs parallel about two fist widths apart, feet flat. Rotate your toes inward as far as they can go, forcing your weight onto the outside of your foot. Now rotate out as far as you can go, forcing weight onto the inside of your foot. Do 50 reps daily until this is easy. Then you only need to do it once in a while to ensure you haven’t lost your strength.

Towel Crunches: I use a hand towel (wash cloth). Sit as above with a small towel on the ground in from of you with the edge under your toes. Use your toes to crunch up the towel as small as you can get it. Then use your toes to flatten it back out. Do 25 if you can. If not, that is the benchmark of strength you are looking for.

Toe raises: Stand with your back flat against a wall, feet together, flat on the ground, out in front of you about a foot or so. Now raise your toes while keeping your back presses flat against the wall. This works the tibialis anterior muscle on the front of your leg, which helps balance flexor/extensor leg strength and will also keep you from getting shin splints. Do 50 a day until they feel easy, then do them once a week or so for maintenance.
