The leg workout, Plyometrics, and Yoga X are all repeated every week throughout the program, as you know. In each case, the idea is to find ways to make the individual movements more difficult if you get to the point where any movement – or any routine – is no longer challenging enough for you.

The muscle confusion concept applies to the workout program as a whole, as well as to individual routines and exercises. To change things up in order to get the most out of the muscle confusion aspect, here are things I would recommend:

1) Use heavier weights and/or do more reps.

2) Go deeper into each movement. Especially with the leg workout, how far down you go in the lunges and squats makes a HUGE difference in how much you get out of those movements. Same concept applies to Yoga X as well.

3) Wear ankle weights – When it comes to the kicking movements in the leg routine as well as the Kenpo X routine, you can confuse your muscles as well as crank up the intensity by adding weights to your legs.

4) Shorten your breaks – Just because Tony and the gang are taking a break doesn’t mean that YOU have to. Skip or shorten the breaks, or do additional/alternate exercises during break times.

Hope those tips help, Mike, and congrats on getting through P90X so many times! P90X Plus is also on my list for later on, and I’m looking forward to the challenge, as I’m sure you are!
