Insanity-P90X-P90X+-One on One-Hybrid Workouts | Week 2
Insanity Max Cardio Intervals
X-­1-­sane 30 Week Beachbody Hybrid Calendar

Slotted this leg/upper body cardio insanity instead of Legs & Back P90X today -- nice. Big time sweat, brought myself to the brink a few times, ended with maxed out muscles and able to handle to breath work. Nice.
