We have all seen the rubbish exercise equipment on infomercials. Thankfully I have never seen a TRX infomercial, but the gear is in my gym. Having been taught how to use it in the gym, and given that my work keeps me traveling away from home 2-3 days a week it was suggested that I get a TRX with a door anchor. So I did. The cliche is true. It has changed my body shape, and the way I train. In fact I am writing this review from my hotel room and my TRX is in my bag resting...from the workout I put it through yesterday!!! Used properly the TRX can change your life!
