Learning how to box squat is a valuable skill for anyone struggling with knee pain. Better yet, this squat is a fantastic alternative for anyone who doesn't feel comfortable doing regular squats.
Many people don't realise that squatting is an essential human movement. It's an important skill to master and maintain for great hip, low back, knee, and ankle joint health. But if any of those areas currently feel uncomfortable with regular squatting, take the time to learn how to box squat instead.
Whether it be knee pain or general discomfort, the box squat allows us to alter the way we load our knees. It allows us to maintain a more vertical shin for longer, decreasing the amount of forward shear going through the knee. This is an important consideration if you have a meniscal injury or some knee wear and tear.

Why Choose the Box Squat?
The traditional squat is a fantastic movement, but it can be problematic for certain knee conditions. When you squat, the angle of your shin relative to the ground influences how much shear force passes through your knee joint. A more angled shin (knee travelling further forward over the foot) increases anterior shear forces on the knee.
For someone with meniscal injuries, patellofemoral pain, or general knee wear and tear, this increased shear can be uncomfortable or even aggravating. The box squat changes this by allowing you to sit back more, keeping your shin more vertical throughout the movement. This reduces anterior shear and can make squatting feel much more manageable.
The box also provides a clear target for depth, which can help with confidence. You know exactly how far you need to go, and you don't have to worry about sinking too low or not low enough.
How to Box Squat Correctly
Here's a step-by-step breakdown of proper box squat technique:
- Set up your box - choose a height that allows you to squat to at least parallel (thighs parallel to the ground) or slightly above. A sturdy box or bench works well.
- Position yourself - stand with your feet slightly wider than hip-width, toes pointed slightly outward. The box should be close enough that you can reach it by sitting back.
- Initiate the movement - begin by pushing your hips back as if you're about to sit down. Keep your chest up and your spine neutral.
- Control the descent - lower yourself under control until your glutes gently touch the box. Don't crash into it or collapse onto it.
- The pause - briefly pause on the box. This eliminates any bounce and ensures you're working from a dead stop.
- Drive up - drive through your heels and mid-foot to stand back up. Think about pushing the floor away and keeping your chest proud.
Throughout the movement, pay attention to your knee position. They should track in line with your toes, not collapse inward. Your shin should remain relatively vertical compared to a regular squat.
Post-Operative and Rehab Applications
Clinically, I find teaching my patients how to box squat is a fantastic post-operative knee exercise at the appropriate time. Patients often feel far more comfortable doing box squats before progressing back to regular squats eventually.
After knee surgery - whether it's meniscal repair, ACL reconstruction, or other procedures - regaining strength and confidence in squatting is crucial. But jumping straight into full-depth squats can be intimidating and potentially problematic. The box squat offers a middle ground:
- It provides a clear endpoint, reducing fear of going too deep
- It reduces shear forces through healing tissues
- It allows you to build strength and confidence progressively
- It can be regressed or progressed by adjusting box height
As strength and confidence improve, you can gradually lower the box height or transition to regular squats. But for many people, the box squat remains a valuable tool even in the long term.

Frequently Asked Questions
Is the box squat easier on knees than a regular squat?
For many people, yes. By allowing you to sit back more and keep your shin more vertical, the box squat reduces anterior shear forces on the knee. This can make it more comfortable for those with meniscal issues, patellofemoral pain, or general knee sensitivity. However, individual responses vary, so it's worth trying with light weight first. At the end of the day we want everyone to feel comfortable doing both.
What height box should I use?
Start with a box that allows you to squat to just above parallel - where your thighs are roughly parallel to the ground. As you build strength and confidence, you can gradually lower the box height. The key is finding a height that challenges you without causing pain. A sturdy bench, plyo box, or even a stack of plates can work.
Can I do box squats if I've had knee surgery?
At the appropriate time, yes. Many patients find box squats more comfortable and confidence-building than regular squats during post-operative rehabilitation. However, always get clearance from your surgeon or physiotherapist first. The right timing depends on your specific surgery, healing progress, and rehabilitation protocol.
