New Move Monday.

Every Monday I share a new move I've tried, courtesy of a website, trainer or stranger at the gym...

Women's Health

This week it's the fitness ball mountain climber from Women's Health.

Place your hands on a fitness ball and extend your legs behind you in a push-up position, with your body forming a straight line from your neck to your ankles. Raise your right foot off the floor and slowly bring your right knee up towards your chest, then lower it. That’s one rep. Repeat with the left leg, and continue alternating until you’ve done 10 to 12 reps with each leg.

It's tricker than it looks and demands a lot of strength from your core. But as they say: no pain, no gain.
