1
Lie supine on your back with legs extended, arms at sides with palms down for support, torso relaxed against the floor, and head neutral.
2
Engage core and press lower back slightly into floor. Keep one leg extended on the ground while preparing to lift the other leg.
3
Slowly lower the lifted leg toward the floor in a controlled manner, extending the knee while keeping the hip flexed, allowing the quadriceps to lengthen under tension.
4
Drive through the quadriceps to lift the leg back up to starting height with a controlled motion, focusing on knee extension. Return to the top position and repeat for desired reps before switching legs.
