1. Do you prioritize your training to protect your knees? 
2. Are you experiencing aches and pains in your knees that discourage your training? 
3. Do you have the confidence in your knees to perform during workouts and during sport competition? 

If you want to protect your knees you’ve got to understand how to train your body based on how you function. Outside of a direct trauma related injury, or some unique medical condition there are several variables that can cause knee pain and instability. However most of these will have more to do with what you’re doing, or not doing in your training.
