1
Sit upright on a bench or elevated surface with your back straight and core engaged. Position yourself so your feet hang freely off the edge with knees at approximately 90 degrees.
2
Keep your hands placed behind you on the bench for support. Maintain an upright torso position throughout the movement. Ensure your feet are positioned shoulder-width apart.
3
Slowly lower your leg by allowing the knee to bend, bringing your foot toward the ground in a controlled manner. This is the eccentric phase where the quadriceps lengthens under tension.
4
Drive through the quadriceps to extend the knee, lifting your foot back up to the starting position where the leg is nearly straight. Squeeze the quadriceps at the top of the movement before lowering again.
