It is extremely misleading to focus on the alleged risks of weight training on children when biomechanical research shows that simple daily activities such as running, jumping, striking or catching can impose far greater forces on the musculoskeletal system than very heavy weight training. <br>To illustrate his point, Siff compared the stress of squatting with running.  Suppose that one child runs a few hundred meters a day in some sporting or recreational activities. This can easily involve several thousand foot strikes in which the reaction force imposed on the body can easily exceed 4 times bodyweight with every stride. Now let another child do a typical average weight training session with 3-5 sets of squats (say, with 10 reps, 8, 6 and 4 reps), with bodyweight or more for the last set. That bodyweight is divided between the two legs, so that, even taking acceleration into account, the loading per leg is bodyweight or a little more, while the spine is subjected to the full load on the bar. In other words, the legs and spine in controlled squatting are exposed to significantly less force than in running and jumping. Normally, exercises such as squatting will be done no more than twice a week for a total of about 60 repetitions, while the running child will run every day and subject the body to those many thousands of impulsive foot strikes. <br> It does not require much scientific knowledge or computational genius to see that the cumulative loading imposed by simple running aercise can build a solid foundation of strength whic affects the Hamstrings, Quads, Hips and Lower Back. The Hex Bar exercise builds functional hamstring jumping strength. Therefore, a jump stance should be used. Keep the hips down and the head up. Spread the chest to lock-in the lower back. Do once or twice per week. This is a BFS Core Lift exercise. For back safety, lightly bounce the weight off the floor when doing reps. Keep the repetitions to five or less.ase your stride length with the back leg drive. You want to run tall. However, to plant the foot directly under the hips is an advanced concept. Therefore, I want to devote a whole article to that technique at a later date. I will have a 4.2 forty-athlete show you some great drills to more fululIVstand this concept.<br><br>8. Your forward leg should initially lift forward, not up. <br><br>The lower leg should hang before planting with your foot and toes up. Your back knee should fully extend on the follow-through, or end-of-the-leg drive. Look at Stefan and Tim once again. The photo was taken at the perfect time to see the all-out extension of their back legs. Again, coaches, if you do some video analysis from the side, you will see that most of yur athletes will never straighten the back leg. Every stride will be performed with a bent bak leg. There is no way you can become really fast with bent legs. Therefore, if you want to run really fast, you will have to master how to run with a back leg that looks like Stefan s.<br>Look at Figure 13. This is our famous hip flexor stretch. If you do this one right, it will help you to increase your stride length and therefore your speed. Remember, when you stretch you want to look like a sprinter. The right-hand photo shows John in a correct position. You must force your hips forward and down. You are supposed to feel the stretch in your hip flexor (groin area). If you don t, your position is incorrect.<br>Look atFigure 12. The left photo shows the toe down, while the right photo shows the toe up. You want your toe up. It will make a huge difference. Study Figures 14-15-16. This is one good way to help athletes learn the vital sprint principle of Toe Up. Detail, detail, detail.<br>A wonderful new sprint aid has just been designed to help you keep your toes up. It is ca
