Hack Squat

Hack Squat is one of the top quads exercises using machine. Full breakdown of proper form, common mistakes and FAQs.

How to perform it

• Feet shoulder-width with toes turned out 15–30°.
• Brace your core and take a deep breath (Valsalva) before descending.
• Sit hips back and down until thighs are parallel to the floor or lower.
• Drive through mid-foot, pushing knees out in line with toes.
• Exhale at the top. Aim for 6–10 reps × 3–5 sets.

• Use a lifting belt above 80% of your 1RM.
