Title: be careful--can mess up your shoulders
Review: I wanted something for high-rep upper body work, so I picked these up. They're perfectly fine for just doing some pushups, but if you get more intense and follow the advanced programs, they can really mess up your rotator cuffs if you have any weakness there (and most of us do). There are much safer exercises to get the same effects. So again, if you just want a good way to do some pushups without straining your arms and wrists, these things are fine. But don't go hardcore with them or you will regret it.
