The exercise ball back extension with hands behind head is a bodyweight movement that strengthens the lower-back muscles (erector spinae), with the glutes (gluteus maximus) assisting to drive the extension. Draping your torso over a stability ball turns it into a soft pivot, and placing your hands behind your head increases the lever and the demand on your spinal extensors.
Cómo hacer el Exercise Ball Back Extension With Hands Behind Head
- 1Kneel in front of a stability ball and roll your torso over it so the ball sits under your hips and lower abdomen.
- 2Extend your legs back and brace your feet against the floor or a wall, setting them about hip-width apart for a stable base.
- 3Place your hands lightly behind your head with your elbows pointing out, and let your upper body curve down over the ball.
- 4Brace your core and squeeze your glutes, then raise your chest and shoulders by extending your spine until your body forms a straight line from head to heels.
- 5Pause briefly at the top without arching past a neutral, straight-line position.
- 6Lower your torso back over the ball under control until you feel a gentle stretch through your lower back.
- 7Complete your reps, then carefully roll forward off the ball to finish.
Consejos de técnica
- Keep your neck in line with your spine and let your hands rest behind your head rather than pulling on it.
- Lead the movement with your chest and let the squeeze come from your glutes and lower back, not from yanking with your arms.
- Use a slow, controlled tempo in both directions to keep tension on the erector spinae throughout the set.
- Position the ball under your hips so your spine has room to flex and extend through a full, comfortable range.
- If balancing is hard, widen your feet or brace them against a wall for extra stability.
Errores comunes
- Hyperextending and over-arching the lower back at the top, which compresses the spine and risks lower-back strain.
- Pulling on the head and neck with the hands, which strains the neck and takes work off the target muscles.
- Using momentum to bounce up instead of controlled extension, which reduces tension on the erector spinae.
- Placing the ball too high under the chest, which limits range of motion and makes the lift harder to control.
- Letting the feet slip because they aren't braced, which costs stability and cuts the set short.
Preguntas frecuentes
What muscles does the exercise ball back extension with hands behind head work?
It primarily targets the erector spinae, the muscles running along your lower and mid spine, with the gluteus maximus assisting to drive the extension at the top.
Why do I place my hands behind my head?
Holding your hands behind your head lengthens the lever and shifts more load onto your spinal extensors, making the movement harder than keeping your arms at your sides or crossed on your chest.
Is this exercise good for beginners?
Yes. It is a bodyweight movement on a stability ball, so beginners can start with the arms crossed on the chest and progress to hands behind the head as their lower back gets stronger.
How many sets and reps should I do?
Two to three sets of 10 to 15 controlled reps is a sensible default. Focus on a smooth range of motion and a brief squeeze at the top rather than chasing heavy fatigue.
Where should I feel this exercise?
You should feel it working through your lower back and, at the top of each rep, your glutes. If you feel it mainly in your neck, you are likely pulling with your hands instead of extending your spine.
