So are you keeping it low impact. I am definitely for that! Can you tell me more about it? I am interested I believe they are 30 mins yes? I have become a convert to the 30 min workout. Before it had to be an hour or I didn't feel like I had done enough. Now not so much and if I do want to go on I just add on something. Glad you are enjoying P90X3. I have only heard good things about it.
