How to Perform the Stability Ball Side Bend
- 1
Lie on your side over a stability ball, with your waist and hip supported.
- 2
Brace your feet against a wall or on the floor for stability.
- 3
Place your hands behind your head or across your chest.
- 4
Laterally flex your waist to raise your torso upwards.
- 5
Squeeze your obliques at the top of the movement.
- 6
Lower slowly back to the starting position and repeat on the other side.
Common Mistakes to Avoid
- !Rushing reps instead of controlling the lowering (eccentric) phase — aim for 2–3 seconds down.
- !Letting form break down as reps add up. Stop the set when technique slips, not when you physically can't do another rep.
- !Using momentum to swing through reps. Pause briefly in the contracted position to keep tension on the muscle.
Tips for Better Form
- ✓Breathe out during the effort (concentric) and breathe in on the return (eccentric).
- ✓Use a mirror or film yourself on your first session — your perceived form and actual form often differ.
- ✓Keep ribs down and lats engaged — this keeps tension on the core, not the hip flexors.
- ✓Start each set with 1–2 warm-up reps at a lighter load to groove the movement.
