1
Sit on a bench or floor with torso reclined back at approximately 45 degrees, supported by hands and forearms. Position one leg bent with foot flat on ground for stability, and extend the other leg straight out in front of you.
2
Ensure your core is engaged and your back maintains contact with support. Keep your extended leg relaxed and ready for movement. Your supporting hand should be firmly planted for stability.
3
Slowly lower the extended leg by bending the knee, bringing the heel toward your glutes in a controlled manner. This is the eccentric phase where the quadriceps lengthens under tension.
4
Drive through the quadriceps to extend the leg back to the starting position. Straighten the knee fully by contracting the quadriceps concentrically, then hold briefly at full extension before repeating the movement.
