What is the proper proprioceptive regression for a bodyweight squat on a BOSU ball?

1. Bodyweight squat on the ground

2. Single-leg squat on the floor

3. Supported squat with assistance

4. Squat with weights

The correct answer is: Single-leg squat on the floor

In the context of proprioceptive regression for a bodyweight squat on a BOSU ball, transitioning to a single-leg squat on the floor provides a valuable adjustment. The objective of proprioceptive regression is to modify the exercise to make it easier while still maintaining a focus on balance, stability, and movement pattern. A bodyweight squat on a BOSU ball is a more advanced exercise that requires a certain level of balance and stability. When using the BOSU, the surface provides an unstable environment, which can challenge proprioception. By regressing to a single-leg squat on the floor, the individual is still engaging in a complex movement but in a more controlled setting that prioritizes core stability and lower body strength without the added instability of the BOSU. This transition allows for the development of single-leg strength and stability, while also reducing the overall challenge of maintaining balance that would come with an unstable surface. It enables a gradual increase in difficulty while ensuring the individual can perform the movements with proper form and reduced risk of injury. The single-leg squat on the floor serves as a more stable option than performing on the BOSU, effectively allowing a participant to strengthen the necessary muscles and refine their squat mechanics.
