Strengthen and tone your abs, shoulders, arms, and back with the Element dual ab wheel. The unit teams up a pair of nonskid wheels and two easy-grip handles. To use, simply get on all fours, grab hold of the handles, and glide the wheels back and forth across the floor. At various points during the exercise, you'll work every major upper-body muscle group as your torso adjusts to the movements. The dual ab wheel comes with an instructional fitness guide.
