Climbing a mountain will feel like a walk in the park after completing this muscle-hammering drill. "Loaded stepups and dynamic stepups activate the same core and leg muscles you'll use on the mountain," says BJ Gaddour, C.S.C.S., creator of Men's Health StreamFit. "Plus, the added weight mimics carrying a heavy pack the entire way to the summit." No easy feat. But if you can finish 10 rounds of this challenge in 10 minutes, you have the muscular endurance and aerobic stamina to conquer any peak. (Build muscle and fry fat all over with this killer Total-Body Kettlebell Workout.)
