Seated Single-Leg Knee Flexion

Sit on the floor with your legs extended straight in front of you and place your hands behind you for support.

Lean your torso back slightly while keeping your chest open and your core engaged.

Bend one knee and slide your heel back toward your glutes as far as comfortable.

Pause briefly at the top of the movement, squeezing your hamstring muscles.

Slowly slide your heel back out to the starting position in a controlled manner.

Complete all your repetitions on one side before switching to the other leg.
