Below is optional equipment that is not required to successfully complete the program -
(1) Yoga Mat. This makes the p90x abdominal exercises and the p90x yoga much more enjoyable ( a hard wood floor or carpet rubbing against your skin doesn't feel all that great).
(2) Yoga Blocks, If you are a beginner at Yoga like i was, then these will really come in handy. These will help stabilize you when doing difficult poses.
(3) Push Up Bars. If you have issues with your wrists, then these will help alleviate stress on your wrist joints when doing pushups ( you will do an extensive amount of pushups with the P90X workout).
So there you have it ! You now know exactly what equipment you need to sucessfully complete the P90X WORKOUT.
