I've only done the shoulder work so far, and then I've previewed the rest. From what I can tell, the intensity seems right up there with GS. There are only a few band exercises overall. Her approach is more of a push-pull/superset form so you don't go "all out" on any one body part at once but by the end you feel it! The rep speed/count seems more straight forward, doesnt seem to be alot of pulses, 3 up 1 down variety which was a nice change I thought. I cant wait to do the all upper body premix.
