Step 1: Lie flat on your back with your left knee bent and foot flat on the floor. Keep your right leg straight and arms at your sides, palms down.

Step 2: Tighten your right thigh and core muscles to keep the leg straight.

Step 3: Slowly lift your right leg to the height of your bent knee, keeping the movement controlled and steady.

Step 4: Pause briefly at the top, then slowly lower the leg back down without letting it drop or touch the floor fully.

Step 5: Perform 10–15 repetitions, then switch legs. Complete 2–3 sets per side.

This exercise builds strength in the front of the thigh and hip, helping with walking, climbing stairs, and improving knee joint stability.
