I...realized that these workouts are exactly what you put into them. If I push myself to work through the stuff that is hard, I feel it in my muscles and it makes me stronger.
Do you remember that first-time pregnancy feeling where your body is freaking out with all the new stuff and trying to build a person in your tummy? P90X is kind of like that, but it's re-building the body you already have. It hurts and it's amazing all at the same time.
