The Russian twist is a seated exercise. After a five-minute warm-up of rhythmic activities, such as walking or light cycling, sit on the floor or on a mat with your knees bent, your heels on the floor and your toes pointing up.
This strengthens the transverse abdominis muscle, which is the deepest layer of abdominal wall muscle tissue. Inhale and rotate your torso and the medicine ball to the right. Exhale and return the ball to the center. Repeat to the left. Your abdominals are the target muscle group for the Russian twist. When performed properly, the medicine ball twist strengthens the rectus abdominus, the main stomach muscle that runs the length from the ribs to the pelvis.
