Just thought i would share what i read on Alwyn Cosgrove's blog. For those who don't know him, he is a very respected trainer, and you should check him out. Well, I guess he really likes the TRX and plans on making an Afterburn Fat-loss DVD with the TRX team. Which should be awesome! He also just posted a metabolic workout he created on the TRX, check it out here http://alwyncosgrove.blogspot.com/ .
