I ordered the TRX Pro as it seems to give me the most flexibility for hooking onto things. Im 52YO and have done all different kinds of weights in my lifetime. And injured just about every joint along with it. At 6'5 with a 6'9 wingspan, lifting has always been difficult. The TRX hits areas in a whole new manner. I love its versatility. The only downfall for me-I ordered the PRO because of the adjustable foot straps. Yeah so if you have a tiny foot its good. Any foot, especially in a shoe (size 14 here) that has some size, the adjustable doesn't work so well-it only adjusts smaller. It would've been nice if the straps adjusted open further. Once I twist my foot into the strap and rotate it to where it goes, then it adjusts in to secure my foot. However this is a small inconvenience to the overall exceptional product and workout variances obtained.
