I have flat feet which causes my knees to cave inwards when standing, walking etc.
I have insoles I have to wear insoles for my shoes to give my some arch and support on the inside of my feet to bring my knees sort off out/level.
Now I use squat shoes as they provide the foot support and are sturdy etc.
However when I get to a “heavyish” weight my knees will cave in, I cannot get enough hip/glute activation to keep my knees from coming in. I squat low bar with a just outside of shoulder width stance.
I try to screw my feet into the floor and my toes facing outwards slightly and really try to sink into my hips and keep my knees over my feet in a normal motor pattern, but when the weight gets heavy my knees will come in. Now this isn’t just my 1RM, this is 80% or so.
Are there any exercises you can recommend me to do Jim, any mobility drills, just anything that will fix this issue?!
I use a hip circle to warm up, to try to open my hips and get my glutes firing, it helps but doesn’t fix it.
