I would get the Gym Styles - Back, Shoulders & Biceps and Chest & Triceps. Also, the Slow & Heavy Series - Triceps & Biceps, Chest & Back and Legs & Shoulders. These are great for building strength and muscle.
I second Marcy!!!!! GS is the BEST imo...
2 upper premixes as well... I just completed the Timesaver Premixes on both Uppers for a COMPLETE upper in 60 min.......I am BURNIN' so good!
