1
Lie on your back on a mat or floor with your head supported, arms at your sides for stability, and one leg bent with foot flat on the floor while the other leg is extended straight out
2
Ensure your lower back maintains neutral contact with the floor, engage your core, and keep the supporting leg's foot planted firmly to maintain stability throughout the movement
3
Slowly lower the extended leg toward the floor in a controlled manner, allowing the knee to extend and the hip to flex, feeling a stretch in the quadriceps and hip flexor of the extended leg
4
Drive through the extended leg and contract the quadriceps to lift the leg back to the starting position level with the bent knee, then return to the initial position and repeat
