Single Leg Squat. What You Want. What You Don’t Want.
The single leg squat helps with stability, knee stability and strength. Start with a higher box to feel things out at first. Use a counterweight such as a light pair of dumbbells to help you with your technique.
A main focus on the single leg squat is controlling the down motion. Avoid dropping fast onto the box. The more control and steady pace you have while going down, the more beneficial the single leg squat will be building knee stability.
We incorporate single leg squats for this reason and for unilateral strength, this helps focus on a strengthening a weaker side to reduce injury.
