This is probably the routine most associated with Mike, although he never actually did this one himself. This was a routine he created for clients. The routine was intended to be performed Mon/Wed/Fri with the option to go to a non set day schedule of however many days between workouts your recovery demanded as you became more advanced. As always, 6-10 reps to positive failure with keeping forced reps and negatives in your pocket as needed.

Who it's for

Athletes of all experience levels
Athletes focused on gaining both size and strength
