1 - Sit on the floor with your knees bent and your feet flat. Lean back slightly, keeping your back straight, and lift your feet a few inches off the ground.
2 - Hold a weight or a medicine ball with both hands close to your chest, or you can do it without any weight to start.
3 - Rotate your torso to the right, bringing the weight or your hands beside your right hip. Keep your feet off the ground and your balance.
4 - Rotate your torso back to the center, balancing on your sit bones.
5 - Now, twist your torso to the left, bringing the weight or your hands beside your left hip.
6 - Continue alternating between right and left twists for the desired number of reps or time, all while keeping your feet off the ground.
