Hack Squat vs Leg Press: Which Builds Bigger Legs?
Both are leg-day staples. Here's how the hack squat and leg press compare and how to use each.
Leg Press and Hack Squat Machines
1. How They Differ
On a hack squat, you stand on a platform with pads on your shoulders and squat down an angled track. On a leg press, you sit back and push a weighted sled away with your feet. The hack squat keeps your torso more upright and involved; the leg press supports your back fully.
2. Side-by-Side
| Factor | Hack Squat | Leg Press |
|---|---|---|
| Quad emphasis | Very high | High |
| Glute involvement | Moderate | Moderate (higher feet = more) |
| Spinal loading | Some | Minimal |
| Learning curve | Moderate | Easy |
| Load potential | High | Highest |
3. Hack Squat Benefits
- Deep knee bend for strong quad development
- More squat-like than the leg press
- Built-in safety stops
4. Which Should You Choose?
Both build big legs. Use the hack squat as a primary quad movement and the leg press for extra volume, or rotate them through training blocks. If you have back issues, the leg press is usually more comfortable.

Place your feet shoulder-width on the platform, slightly forward of center. Keep your back pressed against the pad and your core braced. Lower under control until your thighs are at least parallel, then push through your whole foot. Avoid letting your knees cave inward or your heels lift.
6. Leg Press Form Tips
Keep your lower back and hips flat on the seat, set the safety stops and lower only as far as you can without your hips rolling up. Push through your heels and mid-foot, and stop just short of locking your knees.
7. Programming Both
Start leg day with hack squats for 3 to 4 sets of 6 to 10 reps, then finish with leg presses for 2 to 3 sets of 12 to 15. This combines deep quad loading with high-volume work. Alternatively, rotate them every four to six weeks.
8. Home Gym Options
Leg press hack squat combo machines give home lifters both movements in one footprint, making them a popular choice for serious home gyms.
9. Which Is Better for Glutes?
Both can work the glutes, especially with a deeper range of motion and higher foot placement. The leg press allows a higher foot position that emphasizes the glutes and hamstrings, while the hack squat tends to emphasize the quads. For glute focus, combine either machine with hip thrusts and Romanian deadlifts.
10. Safety Considerations
Use the safety stops on both machines, avoid locking your knees and choose loads you can control through a full range of motion.
Final Thoughts
In hack squat vs leg press, neither wins outright. The hack squat delivers deeper quad work in a squat pattern; the leg press lets you move huge loads with full back support. Use both for complete leg development.
