We did three weeks of Chertow's camps to get my daughter ready for Western Regionals and Nationals, and other than her first match at Regionals, she wrestled very well as a result. We plan on three more weeks as well.
Lots of technique, lots of drilling, lots of live wrestling, lots of training tips, and Chertow would wear out the energizer bunny with his intensity. That kind of intensity is also something he demands out of his staff..... and he hires a lot of staff plus encourages dads and coaches to help out. These camps also break up into seperate groups so the little ones are not forgotten, while the older kids can keep up the intensity.
