Take off your pants. You heard me. Take off your pants and go to the mirror and stand sideways. Look down at your gluteal junction the point where your caboose meets your hamstring and look for something called a gluteal fold. A well-developed hamstring/glute junction is smooth. In other words, the hamstring flows uninterrupted into the glute. Now, answer honestly do you have a smooth junction, or is the fold so pronounced you could store the wooden handles of garden tools back there, firmly entrenched between the heft of your ass and the tops of your hams? If you're like most people, chances are you could be a regular Edward Scissor-butt.

You may scoff and assume that this flabby rear syndrome is a problem faced merely by those hefty women who wear blue tights and are seen in never-ending supply at local K-marts, endlessly pushing their carts up and down the aisles in search of blue-light specials, but it's not. It's common to even the most fit athletes, bodybuilders included.

It never occurred to me though, until a few months ago when I was reading through all the Testosterone e-mail at the beach. In between letters, I was bird-dogging women, as any testosterone-laden man worth his salt will do, when it occurred to me that real first-class behinds are few and far between. I then, shudder, began looking at men to see if they were in the same keel-heavy boat. A lot of them were in worse shape.

I didn't think too much of it until later when I was flipping through the pages of one of the other bodybuilding mags. Lo and behold, there they were gluteal folds galore. Even some high-level bodybuilders had bad upper hamstring/glute development.

I started going through a mental inventory of athletes swimmers, football players, tennis players all lacked proper development. Then it hit me. The only athletes who are well-developed in this area are runners not those anemic-looking long distance runners but sprinters.

Personally, I've always looked at sprinters as spiritual cousins of bodybuilders. The best ones train religiously with weights, and their main activity, sprinting, has much the same physiological action on muscles as weight training as both activities recruit a good degree of fast-twitch muscle fibers. In fact, there aren't many bodybuilders who wouldn't trade legs with someone like Ben Johnson (and no, the small amount of steroids he was taking had very little to do with his overall development).

With all this in mind, I started thinking about incorporating some sort of sprinting program into my training. At best, it would increase my hamstring/glute development, along with giving my quads a new type of stimulation; and at worst, it would give me more speed for my tennis game. It was a win-win situation.

It required a little work, though. I sought out the advice of a couple of higher authorities. The first was Charlie Francis, who was runner Ben Johnson's coach. Francis is the author of a great book on running and training in general called "The Charlie Francis Training System." The book is full of great stuff that I was able to digest. My second source of info was none other than our own Coach Poliquin whose expertise isn't just limited to strength training, but all kinds of training. Together, the "three" of us were able to put together a sprinting program to increase thigh development and augment my regular weight-training program.

Did it work? Yeah. I think my legs look better than they ever have, and I certainly haven't lost any size or strength. If anything, I gained a little size, not to mention giving my calves a much-needed kick in the pants.

I'll describe the actual program first, and then I'll talk about more mundane things like mechanics, form, and hamstring/quad imbalances.

TC's 12-Week Sprint Program

Before you try this program, be aware of the difference between sprinting and running. As sprinter Perry Duncan once said, "You run on the ground you sprint over it." In other words, don't just plod through your "sets" like some aging Clydesdale; race through them.

Before attempting a sprint, warm up very, very well. Sprinting puts a tremendous amount of stress on the tendons, so make sure you've done your preparation. For most people, this involves jogging for a few minutes, followed by several minutes of rigorous stretching. Make sure you have some shoes that offer plenty of arch and heel support, too. I once tried running in some of those Atomix weight-training shoes and screwed up my Achilles tendon for a full year!

The program itself is simple:

You're going to run ten "sets" of 25 yards, taking a flying start instead of a sprinter's start. (A flying start involves beginning to run from a standing position several yards back of the start line so that you're running at full speed by the time you hit the first yard.) You'll rest 60 seconds between each sprint.

After doing 10 "sets," you'll rest 10 minutes and then do ten more sets.

This workout will take the place of one regular weight-training leg workout. So, if you work legs once every five days, you'll do sprints once every ten days. And, on every second sprint workout, increase the sprint distance by 5 yards so that by the eleventh workout, you'll be sprinting for a full 50 yards on each "set."

This may not seem like a lot of work, but believe me, if you're not used to sprinting, you'll have trouble walking for the next few days.

A Few Words About Form

Most people can't imagine that running requires any special form, but it does. Sprinting is even more unforgiving. Of course, I'm not trying to turn you into a track athlete, but if you keep a few things in mind, your sprint workouts will be a lot more satisfying and a lot more rewarding.

For one thing, keep your torso erect. You're not racing against anybody, so you don't need to lean into the finish line. Secondly keep your head high. Use your arms to power your body, and with each stride, pump your arms furiously so that the hand of the driving arm comes up to your face.

The most important thing to remember and probably the hardest thing to do is to keep your shoulders relaxed while sprinting. According to Charlie Francis, if your shoulders start to rise, the hips lock up. If they're tense and pulled upwards around the neck and they're not able to roll forward and backward with each stride, the hips won't function correctly. If the action of the hips is limited, sprinting efficiency is limited, too, since the most of the greatest forces are generated around the hip joint.

Quad/Hamstring Imbalances

You may find, while sprinting, that you'll feel the sprinting in your quads more than your hams. This means that you have a quad/hamstring imbalance and that your quads are proportionately much stronger than your hams. Conversely, as your hamstrings become more developed as you become faster and faster, your contact time with the ground will decrease. You'll become less conscious of your foot pushing off the ground and more conscious of the feeling of up and down.
