How do I stop my knees caving in during burpees?
When I do a standard bodyweight squat I tend to have my knees slightly less than shoulder width apart and I focus on pushing my knees further out than my feet (I basically think about squatting "inside" my knees) I think this is a pretty effective way to protect your knees during squats, but it doesn't work so well during burpees (because my arms get in the way)
With burpees, the advice I've been given is to squat with my feet outside my hands, but then the knees have nowhere to go but in. I tend to try to do them with my feet landing in between my hands but still my knees tend to cave inwards slightly as well as the arch of my foot collapsing. In fact, this lack of a decent way to track my knees properly has led me to stop doing burpees altogether. I can't say I miss them, but.....
Anyway, how do I stop my knees caving in during burpees?
