In the last article we spoke about the first reason why I believe the knees come in during heavy squats. I believe this is because the prime movers in the bottom of the squat (adductor magnus) is trying to find an optimal length tension relationship to push out of the bottom of the hole in a squat. This coupled with the glutes being in a disadvantageous position (unable to force the knees out) can cause some knee in during heavy squat attempts. However, this probably isn’t the only reason why the knees come in during the squat.
The second reason I believe the knees come in during squatting (and also responsible for lower back rounding during deadlifts and other common faults) is your body attempting to use passive tissue structures like ligaments to create stability. Check out the video below to see what I mean:
So in the squat our body’s can take advantage of the passive strength and stability of the ligaments within the knee as well as the boney compression in the front of the hip to help get through the sticking point of the squat. Whether or not this is healthy in the long term for the hips and knees is another question altogether.
If you enjoyed this short clip then I wanted to let you know it’s part of a much longer webinar series included with subscription into my Fitness Pain Free Insiders Online Mentoring Program:
I created this series because coaches and personal trainers everywhere are working with athletes in pain every day of the week. This series will tell you exactly what to do (and what not to do) with these athletes so they can continue working towards their goals and prevent injuries in the long haul.
