I cut out Cardio X and got bored with Yoga. Yoga was cool for the first 4 weeks and then the hour and a half just started boring me.

I started running 3 days a week, and did the workout for that day on the opposite end of the day... meaning, if I did my P90x workout in the morning, I ran that night...or vice versa.

If you're going into basic training, running is NOT something want to leave out
