Okay peeps, another random one, but I wish to share because quite frankly, I'm a bit unsure but here goes. Two workouts. Number one would be the bodywork at the amateur boxing club. One hour split down the middle with cardio then hitting the bags. This with a qualified boxing instructor. Number two is Insanity, 45 minutes I believe. A question of exertion here. Which one do you think causes the most cardio intensity?
