I’m struggling to externally rotate my feet (“spreading the crack” between my feet) and also press through my heels when I squat. How do I balance those two concepts?
Especially on an overhead squat…when I focus on keeping the weight centered over my heels, my toes want to come up and I lose all of that tension.
Sounds like your weight is too far back throwing off your general center of mass.
When squatting you want your feet straightish 9-11 degree turn out is within the acceptable range.
Have the weight to the middle/front part of your heel.
Does that help?
