A lot of Challengers don’t like the idea of daily activity like that. I’m setting a weekly minimum for cardiovascular activity, not a daily. Hey, but if I feel like doing something daily, then I will. But I’m aiming for a minimum of three cardiovascular workouts a week, all being thirty minutes in length. As for strength-training, the regular minimum of two, and if I feel up to it, three. Also, I know you’re starting the Challenge today, so I definitely recommend doing the “make it harder” version for the strength-training. Your body will hate you, but thank you later.
