The Gym Styles series is the best $75 I have ever spent on a fitness related purchase, hands down. Well, maybe second to The Step.
Gym Styles is a 3 day split, and each workout is about an hour. So instead of hitting all the muscles in about an hour, you are concentrating on one, two, or three muscle groups.
Also, Gym Styles has a strength building focus, rather than muscular endurance.
BUY THEM! You will NOT regret it!!
