I did the P90X plan for a year because I loved it so much and saw new muscle definition as well as strength gains in push-ups, pull-ups, etc. After that time I grew bored with it as you can imagine. I began incorporating Cathe in with some P90X in an effort to mix it up, yet keep what I gained. Unfortunately, I've noticed that I've lost strength since then and I'm still feeling bored with my workout and unmotivated. Has anyone been through this and how did you handle this challenge?
