The shoulders should be slightly forward of the bar with the hips back. Just get ready to jump straight up in the air.

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 activities on the lower extremities and the spine is far greater than the cumu
