Do your knees collapse in when you go into a lunge? If so, chances are you are putting too much pressure on the medial ligaments. And I'm all about joint health so I highly encourage you to learn good knee alignment and knee joint health.

Follow along with me in this exercise. This helps keep the pressure in the right ligaments and trains the knees over the toes position.

psst. This has also helped a few athletes' running times improved so...just sayin'.
