Step-by-Step Execution Guide

1

Sit with thighs secured under padded lever, balls of feet on block.

2

Release safety bar, lower heels down to complete stretch.

3

Push up onto toes as high as possible, squeezing soleus.

4

Lower with control.

Common Mistakes & Form Fixes

Using too heavy weights resulting in partial reps.

Jerking knees.

Biomechanical Safety & Injury Warning

Bending knees at 90 degrees slacks gastrocnemius and forces soleus work.
