1
Lie flat on your back on a comfortable surface with your head resting on a pillow or towel. Keep your left leg bent with foot flat on the floor, and extend your right leg straight out in front of you with a slight knee bend.
2
Position your arms at your sides with palms facing down for stability. Engage your core by bracing your abdominal muscles. Ensure your lower back maintains contact with the floor throughout the movement.
3
Slowly lower your right leg toward the floor by allowing the hip flexors to lengthen, controlling the descent with quadriceps engagement. Maintain a neutral spine and avoid arching your lower back. Lower until the leg reaches approximately 6-12 inches above the ground or when lower back begins to lift.
4
Drive through the front of the thigh to lift the leg back up to the starting position, squeezing the quadriceps at the top. Return in a controlled manner without jerking. Complete all repetitions on one leg before switching sides.
