The 60-Second Mountain Climber Test
If the path to a six-pack were paved with supplements or magical abs products sold on infomercials, every guy with some spare cash would have a chiseled midsection. But you don't need to shell out dough to find your abs. All you need is a single body-weight exercise, according to Todd Durkin, C.S.C.S., author of musclemorphosis.com.
"When done at a lightning-fast pace, the mountain climber acts as a strengthening and conditioning drill," says Durkin. That's why he wants you to do as many reps as possible of the exercise for 60 seconds. "It'll sculpt your core from every angle and skyrocket your metabolism, so you'll burn stubborn belly fat long after you're finished."
Here's how to do it: Assume a pushup position with your arms straight. This is the starting position. Lift your right foot and raise your knee as close to your chest as you can. Touch the ground with your right foot and then return to the starting position. That's 1 rep. Repeat with your left leg. Go as fast as possible for 60 seconds. While the first 30 seconds of the challenge may seem easy, the second half will be brutal, so make sure to keep proper form throughout the entire minute.
