I read what roe said about strength training, and about the test for shortness in the hip flexors. My question is, are all these DVD's for strenght training, Power Hour, Pyramids, Slow & Heavy, and Pure Strength ? I have Power Hour DVD, and want to get at least 1 more for now for strength training, I have to get them one at a time, just want to get the right one, for right now, their all good. Any suggestions ? ........... thanks Rhonda :7 :7
