Are Deep Squats Bad for Your Knees? The Truth Backed by Science
Are Deep Squats Really Bad for Your Knees?
If you’ve ever been told, “Don’t squat too deep—it’s bad for your knees,” you’re not alone. This is a common misconception, often repeated in gyms and even by some healthcare providers. But here’s the truth: deep squats, when done correctly, are not harmful to your knees—in fact, they can actually make your knees stronger and more resilient. Let’s dive into the research to set the record straight.
The Science Behind Deep Squatting
A systematic review of 15 studies found that 87% concluded deep squatting does not increase the risk of knee injury (Frontiers in Sports and Active Living). This means that squatting through a full range of motion isn’t the problem—it’s actually beneficial for joint health.
Another key point: shear forces on the knee are actually higher in partial squats than in deep squats. So if you’re avoiding deep squats to “protect” your knees, you might be doing the opposite.
What About the Meniscus?
Some people worry that deep squatting puts extra stress on the meniscus (the cartilage in your knee), potentially increasing the risk of injury. However, research suggests otherwise. When performed with proper form, deep squats do not increase meniscal damage risk. In fact, strengthening the muscles around the knee through a full range of motion enhances joint stability, which can actually help protect the meniscus over time.
Tendon Stress and Knee Health
It’s true that deep squats place greater load on the patellar tendon, which can sometimes cause irritation—especially if you’re not used to the movement. However, gradual exposure to deep squatting actually strengthens the tendon, making it more resilient to stress (Physio Network). Instead of avoiding deep squats, a better approach is to progressively build tolerance, allowing your body to adapt and grow stronger.
Squatting is a Fundamental Human Movement
Think about your daily activities: sitting down, standing up, picking things up off the ground—all of these movements involve squatting. Avoiding deep squats altogether isn’t just impractical; it’s counterproductive. Instead of fearing deep squats, we should focus on doing them correctly and building strength through a full range of motion.
Key Takeaways
Deep squats are not bad for your knees—the research supports their benefits.
Shear forces are higher in partial squats than in full squats.
Meniscus health is not negatively affected by deep squats when done properly.
Tendon stress is manageable, and progressive loading makes tendons stronger.
Squatting is an essential movement, and mastering it can keep you mobile and strong for life.
Final Thoughts: Don’t Fear the Deep Squat
The next time someone tells you deep squats are bad for your knees, you’ll have the facts to prove otherwise. If knee pain is holding you back, the issue likely isn’t the squat itself—it’s how you’re doing it, or a lack of proper progression. If you need guidance, we’re here to help.
