Upgrade Your Crunches With This 1 Move For Rock Hard Abs

Before a few months ago I never used kettlebells in my workouts. Disclaimer: I'm not a kettlebell pro, but I read in one of my books on fixing back pain that doing anti-rotational core exercises (moves where you're not rotating your core, like planks) can alleviate back pain and still keep your midsection looking sexy. The bottoms-up kettlebell carry does require upper-body strength, but you'll be feeling this move the most in your abs.

Fire Up Your Abs and Bum With This 30-Minute Circuit

Here's how to do it:

• Start with a lightweight kettlebell in your right arm. I'm using a four kilogram kettlebell which is roughly 9 pounds.
• Lift your arm up turning the kettlebell upside down, creating a 90-degree angle at your elbow. Be sure to keep your wrist straight. If you notice that your wrist is moving use a lighter kettlebell or a lightweight dumbbell.
• From here, begin walking forward. Take 20 steps forward or walk for 20 feet depending on the space available.
• Switch the kettlebell to your left hand and walk back to your starting point. This completes one round.
• Do four rounds to fire up your abs.
