Have you ever used a hack squat machine and wondered where to place your feet or how low to go? A good setup can make the movement feel much smoother.
The basic idea is simple: set a manageable weight, keep your feet flat, press your back into the pad, lower with control, and push back up. Focus on steady reps before adding more weight.
As the founder of YR Fitness, I have spent decades designing and studying commercial strength equipment. I have seen how small changes in positioning can make a big difference in how a machine feels.
Below, I will show you the setup, foot position, squat movement, and basic sets and reps. Follow each step and you can use the hack squat with more confidence.
1. Adjust the Hack Squat Machine Before You Start
Start with a weight you can control comfortably. If this is your first time, keep the load light while you learn how the sled moves.
Here is a quick setup check:
Check | What to Do |
Weight | Load both sides evenly |
Safety stops | Make sure they are correctly positioned |
Shoulder pads | Check that they feel comfortable |
Sled | Make sure it moves smoothly |
Safety handles | Learn how they lock and release |
Why does this matter? You do not want to figure out the safety mechanism while already supporting the weight.
Take a few seconds to test the machine before starting your set.
2. Place Your Feet in the Right Position
Place your feet around shoulder-width apart on the platform.
Start with:
- Feet flat on the platform
- Toes pointed slightly outward
- Heels fully supported
- Knees moving in the same direction as your toes
This matches the basic squat principles in the ACE bodyweight squat guide, which recommends keeping the feet stable, heels down, and knees aligned during the movement.
What if the position feels awkward? Move your feet slightly higher, lower, wider, or narrower until you can squat comfortably without your heels lifting.
Your ideal stance depends on your height, leg length, ankle mobility, and the machine itself. I usually suggest starting neutral and making only small adjustments.
3. Get Into the Starting Position
Place your back and hips firmly against the pad. Slide your shoulders underneath the shoulder pads and keep your head in a comfortable, neutral position.
Then:
- Grip the handles.
- Straighten your legs enough to support the sled.
- Keep a slight bend in your knees.
- Brace your core.
- Keep both feet firmly planted.
Do not aggressively lock your knees at the top.
Your body should feel secure before you release the safety mechanism. If you still feel like you are shifting around, fix your position first.
4. Unlock Safety Handles
Extend your legs slightly to take pressure off the safety stops. Then rotate or release the handles according to the machine’s design.
Keep your hands on the handles while doing this. Do not start lowering until you know the sled is fully released.
Not sure how the handles work? Check the instruction label on the machine or ask gym staff before starting.
Different hack squat machines can use different locking systems. Never assume one machine works exactly like another.

5. Lower Yourself With Control
Bend your knees and let the sled travel downward slowly. Keep your back and hips against the pad throughout the movement.
Quick Form Check
During the Descent | What You Want |
Feet | Flat on the platform |
Heels | Stay down |
Knees | Track with your toes |
Back | Stay against the pad |
Speed | Slow and controlled |
The ACE squat guidance also recommends lowering until around thigh-parallel or until your form begins to change, such as your heels lifting.
How deep should you go? Only as deep as you can comfortably control.
You do not need to force yourself into the deepest possible squat. Your mobility and body proportions will affect your comfortable range.
I often see people drop too quickly into the bottom because they are using more weight than they can control. Slow down instead of bouncing out of the bottom.
6. Push Back Up
From the bottom, press through your feet and extend your knees and hips. Think about pushing the platform away from you rather than throwing the sled upward.
As you rise:
- Keep your whole foot on the platform.
- Keep your knees aligned with your toes.
- Keep your back against the pad.
- Push smoothly.
- Avoid aggressively locking your knees.
Exhale through the harder part of the lift. ACE similarly recommends extending the hips and knees while keeping the heels down during the upward phase of a squat.
What if your form starts breaking down? Reduce weight.
Controlled repetitions matter more than simply loading extra plates.
7. How Many Sets and Reps Should You Do?
You do not need a complicated routine to start.
Training Goal | Sets | Reps |
Beginner | 2–3 | 8–12 |
General Fitness | 3 | 8–15 |
Muscle Building | 3–4 | 8–15 |
Strength Focus | 3–5 | 5–8 |
If you are new to hack squats, start with 2 to 3 sets of 8 to 12 controlled reps. This also lines up with ACSM resistance-training guidance, which recommends 2–3 sets of 8–12 repetitions with good form and controlled lifting and lowering for general resistance training.
ACSM’s updated 2026 guidance also stresses that your load and training volume should match your goal rather than following one fixed formula for everyone. Its review drew on more than 137 studies and 30,000 participants.
For general health, the U.S. Physical Activity Guidelines recommend muscle-strengthening activity involving the major muscle groups on at least 2 days per week.
Rest around 1 to 3 minutes between sets, depending on the weight and how recovered you feel.
After your final rep, extend your legs enough to engage the safety mechanism. Make sure the sled is securely locked before stepping out.
Conclusion
Using a hack squat machine gets much easier once you know the sequence. Set up the machine, plant your feet, keep your back supported, lower with control, and push back up smoothly.
Start light while you find a comfortable stance and squat depth. Clean, controlled reps are more useful than simply adding more plates.
