Mountain Climbers Steps:
Step 1: Assume a standard push-up position with arms straight. Hands should be placed below shoulders but just outside of shoulder width.
Step 2: Your body should now form a straight line from your heels to your head. This is the starting position.
Step 3: Begin the exercise by lifting your right foot off the ground and bringing your knee as close to your chest as possible. Hold for a moment, then touch foot to the ground. Next, return the foot to starting position.
Step 4: Repeat with the opposite leg. Alternate back and forth for 30 seconds or more.
