I read that ronnie coleman does 1 hour of cardio on the treadmill at 3.1mph, and a 4% incline. Is that a good intensity for an hour? I will usually do like 3.6 - 3.8 mph at 15% incline for an hour......what do you guys think? Thanks
his little ass heart, working for that big ass body.....its probably plenty for him. i warm up higher than he goes for an hour. i start at 3.4 for a 5%. geeeez. plus im sure he has some "help" when hes cutting, cardio alone wont cut it.
