Medicine Ball Russian Twist

Sit on the floor with your knees bent and hold one medicine ball with both hands. Lean back slightly and lift your feet to balance.

Brace your abs and rotate your chest and the ball together to one side. Turn through your torso rather than moving only your arms.

Pass through the center and rotate slowly to the other side. Keep a similar range of motion on both sides.

Engage the sides of your abdomen to rotate and control your torso. Use your front abdominal muscles to keep your torso and pelvis stable.

Avoid rounding your lower back or swinging the ball with momentum. Place your feet on the floor if maintaining balance is difficult.

Exhale as you rotate to one side and inhale as you return toward the center. Continue the same breathing pattern on the other side.

Enter the weight of one ball. Count both the left and right rotations together as 1 rep.
