RUSSIAN TWISTS
This one requires a weight, but it can be anything so get creative. Sit on the floor with your chosen weight in your lap. Keep your back and legs straight, bending only from the hip, and lift your feet off of the floor. Move the weight over to the right- hand side, tap it on the floor in line with your hips, then repeat on the opposite side. If you’re finding it too challenging to keep your feet off of the ground, bend your knees and rest your feet on the ground, but try to maintain the same amount of rotation.
