A medicine ball held at chest height loads the twist while a partner matches your rhythm rep for rep, which keeps pace and range honest in a way solo sets rarely do. Lean back slightly with a straight back, and turn the shoulders fully to each side before reversing.

How to do the Partner Medicine Ball Russian Twist

  1. Sit on the ground with your knees bent and feet flat on the floor.
  2. Hold the medicine ball with both hands in front of your chest.
  3. Lean back slightly, engaging your abs and keeping your back straight.
  4. Slowly twist your torso to the right, bringing the medicine ball towards the right side of your body.
  5. Pause for a moment, then twist your torso to the left, bringing the medicine ball towards the left side of your body.
  6. Continue alternating sides for the desired number of repetitions.

Tip: Pivot on the back foot and let the hips turn with the shoulders so the rotation is shared across the whole body.

Muscles worked

Primary

Abs · Core

The obliques rotate the torso and resist the return, and you should feel the side of the waist tighten on each side as you turn.

Secondary

  • Obliques — The obliques are the prime movers, with the internal and external obliques on opposite sides working together to turn the trunk.
  • Spine — The deep spinal muscles control the rotation and keep the movement smooth.

Common mistakes

  • Twisting from the lower back — the rotation should come from the mid back and hips; keep the lower back neutral and let the hips turn with you on standing variations.
  • Using the arms to swing — on cable and band rotations the arms stay locked out in front of you and the torso does the turning.
  • Rushing the reps — control the return and pause briefly at the end range on each side instead of bouncing back and forth.
  • Loading barbell twists heavy — gravity barely resists rotation, so keep barbell twists light and controlled, and use a cable or band when you want real rotational load.

Where it fits in a workout

Rotations work at the end of a session with the other core work, or as a warm-up before throws and rotational sports. Superset cable rotations with a cable side bend or pull-through on the same stack.

When to talk to someone

  • Chest discomfort, feeling faint or lightheaded, or trouble breathing during or after exercise can be signs of a heart attack. In the US, call 911 right away; elsewhere, call your local emergency number.
  • Heart, metabolic or kidney disease, or symptoms like these when you are active: talk to your doctor before you start or step up training.
