Here we explain how to do this exercise in a perfect way.
-Muscle worked: abs, back
-Difficulty: medium
-Team: nothing or a disc
Sit with your arms stretched out in front of your chest (if you do it with a disc, hold it at that height) and your feet off the floor. Quickly, turn your torso from side to side and touch the floor.
Tips from the experts
Your torso and thighs should form a V to make sure the abdomen is doing all the work.
