Janet Brooks is by far the best instructor at the FIRM. This workout is phenomenal. The upper body moves are unique and she makes it a lot of fun. Her cues are very easy to follow, and she is very straightforward with her coaching. This workout includes a variety of shoulder exercises, pushups and other chest work, biceps, triceps, back (including lower back) - my entire upper body gets worked when I use this workout. I wish I could buy more videos led by Janet Brooks.
