Planning on getting a few bands for some rehab. I'm thinking about getting 1 of each of the following: mini, monster, light, average. Pretty broke at the moment and not really planning on doing band work on bench/squat/dl soon. At least not till my shoulder is better. Does it make sense to get all 4? Or could I probably do without one of the first three. Planning on doing various shoulder/RC exercises, TKEs for my knees, and band GMs. (can hold bar high position for squats okay, but low bar puts to much stress on my shoulder.) I'll probably get the same 4 and maybe strongs one day when I am further along in my training. It's $85 for those four bands + shipping. I think the pack of pairs of mini, light, average, strong is around $180. Let me know what you guys think.
