How to Perform

Sit on the floor with knees bent, lean back to about 45 degrees while keeping your back straight
Hold a medicine ball, plate, or clasp your hands together
Rotate your entire torso side to side, tapping the weight on the floor each side
Keep your feet elevated for extra difficulty
Maintain the lean-back angle throughout

Tips

Rotate from your torso, not just your arms — your shoulders should turn with the weight; if only your arms move, you are cheating
No weight? Clasp your hands together or hold a water bottle; for progression, use a medicine ball, plate, or dumbbell
Use a slow and controlled 2-3 seconds per side — momentum completely defeats the purpose of this exercise
Moving too fast and bouncing the weight off the floor is the most common mistake — every tap should be deliberate
Feel the obliques on each side of your waist contracting alternately — one side shortens while the other stretches on each rotation
