1
Lie supine on the floor inside a power rack with legs extended. Position the barbell across the upper thighs, secured by the rack's safety bars at mid-range height. Hands grip the bar with palms down, positioned shoulder-width apart for stability.
2
Establish a neutral spine position with lower back maintained against the floor. Engage core musculature. Position feet hip-width apart with toes pointing upward. Ensure barbell is centered across proximal thighs.
3
Plantarflex the ankles by pressing the balls of the feet downward and inward in a controlled manner, lengthening the gastrocnemius and soleus muscles. Maintain constant tension throughout the eccentric phase, lowering toes toward the floor without touching it.
4
Dorsiflex the ankles by pulling toes toward shins against barbell resistance, concentrating the effort in the calf muscles. Press through the balls of the feet to drive the toes upward, achieving maximum contraction at the top position. Pause briefly before beginning the next repetition.
