How To Master The Mountain Climber: 60 Seconds To Fit

Did you set a resolution to move even more in the new year? Or, are you just looking to kick off a new fitness routine? Our video series, 60 Seconds To Fit, is here to help. Each one-minute clip breaks down a different exercise, showing you how to do it with perfect form. "In the beginning, you might perform the moves at a slower pace and for a shorter duration than you expected, and that's okay," explains celebrity trainer Suzanne Bowen."Having good form means you'll work the correct muscles — and help prevent injuries. It's about cultivating strength and control," she says.

The Mountain Climber

This simple-yet-challenging move targets your core and upper body.

To do it, come into a plank position on the balls of your feet, with your palms flat on the floor and your wrists below your shoulders. Keep your head in line with your spine (don't let it drop) and contract your abs.

Hold the plank while bringing your right knee under your torso. Return your right foot to starting position and switch legs, lifting your left knee under your torso. Keep switching legs for 20-30 seconds. Rest, and repeat. As you improve, work up to doing the move for 1 minute. Rest, and repeat up to two more times.

The faster your pace, the more of a cardio exercise (and a challenge!) this move will be.
