The Bosu ball single leg squat is a bodyweight balance-and-strength exercise that targets the quadriceps of the working leg, with the glutes and hamstrings stabilizing the hip and the smaller foot and core muscles fighting the wobble. Standing on the unstable Bosu dome trains single-leg strength, balance, and ankle stability all at once, making it a useful progression once a regular single-leg squat feels controlled.
Bosu Ball Single Leg Squat: So führst du sie aus
- 1Place the Bosu ball dome-side up on a flat, non-slip surface with clear space around you.
- 2Step onto the center of the dome with one foot, planting your whole foot for a stable base, and lift the other leg slightly off the ground in front of you.
- 3Brace your core, fix your gaze on a point ahead, and let your arms move forward for balance.
- 4Bend the standing knee and push your hips back to lower into a single-leg squat, keeping the knee tracking in line with your toes.
- 5Descend under control as far as you can with good form, ideally until your thigh approaches parallel, without letting the knee cave inward.
- 6Drive through your heel and midfoot to extend the standing leg and return to a tall, balanced position.
- 7Complete your reps on one leg, step down to reset, then switch to the other leg and repeat for the same number of reps.
Technik-Tipps
- Master a single-leg squat on stable ground before adding the Bosu, so the dome trains balance rather than masking a weak pattern.
- Keep the standing knee tracking over the second and third toes throughout the rep to protect the joint and keep the quad loaded.
- Slow the lowering phase down and pause briefly at the bottom; the controlled tempo gives the stabilizers time to react to the unstable surface.
- Position the Bosu near a wall or rack so you can lightly touch it for support if you lose balance, especially when you are learning the movement.
Häufige Fehler
- Letting the standing knee collapse inward, which strains the knee and signals the glutes are not stabilizing the hip.
- Rushing the reps and bouncing out of the bottom, which sacrifices the balance and control the unstable surface is meant to build.
- Standing off-center on the dome so it tips to one side, throwing off your balance and shifting load away from the working quad.
- Letting the torso pitch far forward or rounding the back to chase depth, which reduces quad work and stresses the lower back.
- Training one leg far harder than the other; uneven reps or depth between sides reinforces strength imbalances.
Häufig gestellte Fragen
What muscles does the Bosu ball single leg squat work?
It mainly works the quadriceps (front of the thigh) of the standing leg, with the glutes and hamstrings stabilizing the hip and the core and lower-leg muscles working constantly to keep you balanced on the unstable Bosu dome.
Is the Bosu ball single leg squat good for beginners?
It is an advanced single-leg movement because of the balance demand. Beginners should first build strength with two-legged squats and a single-leg squat on stable ground, then add the Bosu once that feels controlled.
What is a good alternative to the Bosu ball single leg squat?
A standard single-leg squat or pistol squat on the floor builds the same single-leg strength without the wobble, while a Bosu two-leg squat keeps the balance challenge but shares the load across both legs.
How many sets and reps should I do?
Because it is balance-focused and done with bodyweight, 2 to 3 sets of 6 to 10 controlled reps per leg is a sensible starting range. Stop the set once your form or balance breaks down rather than pushing to failure.
Why is my knee caving in during the squat?
A knee that caves inward usually means the glutes are not stabilizing the hip. Slow down, keep the knee tracking over your toes, and reduce depth until you can hold alignment for every rep.
