Squat (BOSU Ball)
A squat performed standing on an unstable BOSU ball dome, increasing demands on stabilizer muscles, quadriceps, and glutes.
Instructions
- Place a BOSU ball on a stable, flat surface with the dome side facing up.
- Stand on the BOSU ball with your feet shoulder-width apart, centered on the dome.
- Position your arms in front of you or at your sides for balance and counter-balance.
- Keep your chest up and gaze forward throughout the movement.
- Begin the descent by flexing your knees and hips, sitting back while maintaining balance.
- Descend to a comfortable depth, typically parallel or slightly below.
- Keep your torso relatively upright and your knees tracking over your toes.
- Reverse the motion by driving through your legs, extending your knees and hips to stand.
Tips
- The unstable surface requires constant stabilizer muscle activation
- Start with partial depth squats to master the balance before going deeper
- Keep your weight distributed evenly across your foot
- Engage your core throughout to maintain balance and stability
- Start with bodyweight to master the movement before adding external resistance
- This variation significantly increases ankle and lower leg stabilizer demands
