Hack Squat
Also known as:Machine Hack SquatBarbell Hack Squat
Like a bear pressing out of a deep crouch, the hack squat fires up your legs from paw to hip. Whether you're sliding on a machine or gripping a barbell like a tree trunk, this move builds serious leg power and quad bulk.
Instructions
- For the machine: Position yourself under the shoulder pads with your feet shoulder-width on the platform.
- Lower your body by bending the knees and hips until your thighs are at least parallel to the platform.
- Drive through your heels to return to the starting position.
- For barbell: Stand with the barbell behind your legs, resting just below the glutes.
- Squat down by bending at the knees, keeping your chest up and core tight, then push back up.
Benefits
- Strengthens the quads, glutes, and hamstrings.
- Enhances squat mechanics with added control and stability.
- Can isolate the quads more than traditional squats.
- Great for hypertrophy and strength training cycles.
Key Points
- Keep your heels grounded and knees tracking over your toes.
- Do not allow your lower back to round—maintain a neutral spine.
- Use a controlled tempo throughout the range of motion.
- Choose the variation that best suits your comfort and experience.
Common Mistakes
- Letting the knees cave inward.
- Rounding the back or leaning too far forward.
- Using too much weight without proper form.
- Cutting the depth short, reducing effectiveness.
