How to do the exercise ball back extension with arms extended

  1. Step 1: Place the stability ball on the ground and lie face down on top of it, with your hips resting on the ball and your feet against a wall for stability.
  2. Step 2: Extend your arms straight out in front of you, with your palms facing down.
  3. Step 3: Engage your core and slowly lift your upper body off the ball, keeping your back straight and your neck in line with your spine.
  4. Step 4: Pause for a moment at the top, then slowly lower your upper body back down to the starting position.
  5. Step 5: Repeat for the desired number of repetitions.

Sets, reps and programming

Suggested sets, reps and rest for the exercise ball back extension with arms extended 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.
