The elevated-feet Russian twist is a rotational exercise that targets your core, more specifically the obliques. This exercise also increases strength and power in the hips.
Sit on the floor with your knees bent and your hands placed on the back of your head. Lean back so your torso creates a 45-degree angle with the floor. Lift your feet a few inches from the floor. This is your starting position.
Brace your core and rotate your torso to one while fully extending your opposite leg. Pause, then reverse the movement.
Move slowly, focusing on using your core to stabilize your body.
