How to do the Stability Ball Weighted Back Extension
To begin, lie down on an exercise ball with your torso pressing against the ball and parallel to the floor. The ball of your feet should be pressed against the floor to help keep you balanced. Place a weighted plate under your chin or behind your neck. This is the starting position.
Slowly raise your torso up by bending at the waist and lower back. Remember to exhale during this movement.
Hold the contraction on your lower back for a second and lower your torso back down to the starting position while inhaling.
Repeat for the recommended amount of repetitions prescribed in your program.
Sets and reps
| Goal | Sets | Reps | Rest |
|---|---|---|---|
| Muscle growth | 3–4 | 8–12 | 1.5 min |
| Muscular endurance | 2–3 | 15–20 | 1 min |
When you hit the top of the rep range on every set, add 2.5 kg (5 lb) next session and work back up.
Starting points from training research. Stop each set 1–3 reps short of failure.

The spinal erectors keep your back straight under load. Hinges, back extensions and good mornings make them strong; start light and own the position.
