So I've continued to work out...I just haven't been doing p90x. So why is it that after one lousy p90x workout and a long bike ride, every muscle in my body aches. Including my abs. Does this mean I just have to continue to cycle through p90x for the rest of my life to stay in shape? Because obviously doing my walking and biking and pushups did not keep me in shape in between rounds of p90x. How depressing. I like variety in workouts and to think that ten years from now the only way I'll be in shape is to be on round 31 of p90x makes me want to cry.
