📋 How to Do?
- Position your back firmly against the machine pad, placing feet shoulder-width on the platform and shoulders under the pads for secure hold.
- Unlock the safety handles, then lower your body by bending knees until they reach 90 degrees, keeping your core braced.
- Press up through your heels to extend fully, squeezing quads at the top without locking your knees.
- Perform 3-4 sets of 10-12 reps, focusing on controlled eccentric lowering for maximum stretch.
Adjust foot position for personal comfort in hack squats, controlling the eccentric phase to protect knees, and always engage the machine safeties before starting. Warm up with bodyweight squats for mobility. If back issues persist, consult a professional for modifications.
💪 Working Muscles
Primary: Quadriceps (knee extension); Secondary: Gluteus Maximus (hip assistance); Hamstrings (eccentric control); Adductors (inner thigh stabilization)
Equipment Needed: Hack squat machine
Difficulty: Intermediate
✨ Benefits
Hack squats enable heavy quad loading without back fatigue, improving squat form transfer to other exercises while promoting hypertrophy. They enhance knee stability and lower body endurance for sports.
🔥 Burned Calories
Burns Approx. 70-90 kcal per 10 min at moderate intensity
Metabolic Impact: Moderate, focused on quad hypertrophy
Common Mistakes
- Placing feet too high on the platform, which shifts emphasis to glutes and reduces quad isolation.
- Performing partial depth reps, limiting the full quad stretch and hypertrophy potential.
- Locking out knees at the top, which places unnecessary stress on the knee joints.
