I have been using these bands in my work out routine and have been very happy with them. There are five bands of varying resistance. Each band has a pretty quality carabiner at each end, which I really like. I bought a set of Perfects at Wal-mart and they only came with three bands and no metal whatsoever (and only lasted a few months before snapping). This set is already more impressive. I have actually started using the old handles from the broken set with the extra bands that came with this B.M.P set. Using resistance bands for the first time can be a little odd, but once you build a routine with them they actually become a strong asset to your work-outs.
