Instructions
Preparation
- Lie supine on sled with shoulders against pad and place feet
on platform. Grasp handles to sides and straighten knees. Place
toes and balls of feet on lower portion of platform with heels
and arches extending off.
Execution
- Push sled up away from platform by extending ankles as far
as possible. Return by bending ankles until calves are stretched.
Repeat.
Comments
- Not all Hack Squat machines have platform with opened lower
end allowing for this movement but some platforms may accommodate
calf block, see example.
Disengage docking lever if it impedes movements. Keep knees straight
throughout exercise or bend knees slightly only during stretch.
Quadriceps serve as synergist muscle if knees are bent slightly
during stretch.
