How to do the exercise ball back extension with rotation with stability

  1. Step 1: Start by lying face down on the stability ball with your hips resting on the ball and your feet firmly planted on the ground.
  2. Step 2: Place your hands behind your head or cross them over your chest.
  3. Step 3: Engage your core and slowly lift your upper body off the ball, extending your back until your body forms a straight line from your head to your heels.
  4. Step 4: Pause for a moment at the top, then slowly rotate your torso to one side, keeping your hips and legs stable. Emphasize stability control.
  5. Step 5: Return to the center and repeat the rotation to the other side.
  6. Step 6: Lower your upper body back down to the starting position and repeat for the desired number of repetitions.

Sets, reps and programming

Suggested sets, reps and rest for the exercise ball back extension with rotation with stability by training goal
Goal Sets Reps Rest Effort
Strength 3–5 3–6 3–5 min 1–3 reps in reserve
Muscle growth 3–4 6–12 2–3 min 1–2 reps in reserve
Muscular endurance 2–3 12–20 1–2 min 1–3 reps in reserve

Ranges follow the ACSM position stand on progression in resistance training. Muscle grows across a wide range of loads when sets end close to failure (Schoenfeld et al., 2017), longer rests between heavy sets support strength and size (Schoenfeld et al., 2016), and stopping a rep or two short of failure works about as well as training to failure (Grgic et al., 2022). Estimate your working weights with the strength calculators.
