I’ve integrated these into my workouts since March, and they’ve really helped shape my back…Like most athletic women, I’ve always had strong obliques, so creating the appearance of a small waist has been a matter of building up my upper back, the V-Taper, and avoiding all exercises that recruit my obliques. For my dial-in program, I was finishing off my back/shoulder day with 4 sets of 12 of these. They are a heart breaker, and you really get to see what your made of when you’re facing those final 12, let me tell you! The rhythm is the trickiest part in the beginning, at least it was for me. It helped to be told to keep my legs more straight, and a little apart, to snap the upper body up to the bar. Good luck!!
