Knee Pain

List of things that cause knee pain for weightlifters

1. Tense Quads, Hamstrings, Calves, and Feet with lots of trigger points in them
2. Poor Diet.  Eating less inflammatory foods and more fish oil and pineapple will do wonders.
3. Poor Squatting position and movement
4. Strength Ratios out of balance. Ex. Weak VMO’s, or hamstrings compared to the Vastus Lateralis.  
5. Too much squatting volume.  If you are addressing all the above well and your knees still hurt a lot, you should start looking at your training volume.  Keep in mind that discomfort and pain are different.
6. Structural Issues like a torn meniscus or arthritis which need to be evaluated by a professional.
