I loved the P90X program, but found it too strenuous and intense to mix into a triathlon training routine. The intensity of the workouts took away from intensity that I wanted to focus on speed and hill training.
I have however, incorporated some of the exercises in a much-watered-down strength training program that I use.
Runtimpa, I must say that I did do the P90X series and found that it was very strenuous, but at the same time very helpful.. I found that the breathing techiques helped me with my running, and when running trails i found that the jump training really helped me to get through and over small ditches.. I did notice very big changes in my body and mind.. For some reason though I didnt see too much of a time diffrence in my 5ks.. May have just been me.. idk.. I did however love the high intensity!!
In the words of Forrest Gump " I just felt like running!!!"
