Core Connection: 5-Minute Ab Workout

Number 1:

Mountain Climbers

Start in a traditional push-up starting position — shoulders over hands and weight on just your toes.

Bring your right foot forward, bending the knee and putting weight on the ball of your foot.

Switch legs, bringing the left knee forward while moving the right leg back. It feels a little like running in place in a plank position.

For an advanced variation to work your abs more, keep the ball of your foot off the floor as you bring the knee in toward your chest.

Quickly move through this exercise for as long as possible without taking a break — at least 30 seconds! Take a quick breather if need be, but pick up again until one minute is up.
