Exercise of the Week: The Frog Stance Hack Squat
by Christian Thibaudeau

This is also called the Gironda hack slide because Vince Gironda came up with it. To perform it, use the hack squat sled but the following lower body placement and actions:

a) Perform the movement with the heels together and while rising on your toes.

b) The knees are pushed outward as much as possible during the eccentric (negative) portion of the movement.

c) Go back to a straight leg position as you complete the concentric (lifting) portion of the exercise.
