Squats are fantastic for leg strength, but for many, they come with a sharp reminder: knee pain. The good news is that squats shouldn't hurt your knees. In fact, when done correctly, they strengthen the joint.
Common Causes of Knee Pain
1. Knees Caving In (Valgus)
This is the most common culprit. When your knees collapse inward during the movement, strictly pressure is placed on the ligaments. This creates a dangerous misalignment.
2. Weight Too Far Forward
If your heels lift off the ground, all your weight shifts to your toes, putting massive shear force directly on your knees. Keep those heels planted!
3. Skipping the Warm-up
Cold joints and stiff muscles are prone to injury. Diving into heavy or high-rep squats without proper mobility work is asking for trouble.
3 Steps to Fix Your Form
Step 1: The "Knees Out" Cue
As you descend, actively think about pushing your knees outward. Imagine there is a band around your knees that you are trying to stretch. This engages your glutes and protects your knees.
Step 2: Sit Back, Not Down
Don't just drop your hips straight down. Hinge at your hips first, pushing your butt back as if reaching for a chair. This loads your powerful hips and hamstrings instead of just your quads and knees.
Step 3: Check Your Stance
Everyone's anatomy is different. If a narrow stance hurts, try widening your feet and pointing your toes out slightly (15-30 degrees). Find the position where you can squat deep without pain.
When to Stop
Muscle burn is good; joint pain is bad. If you feel sharp pain inside the knee cap, STOP immediately. Rest, ice, and check your form. Using Squat Counter AI can help you ensure your reps are consistent and controlled.
