I sent my O'Lift coach an email about my hip flexor soreness to see what he thought. Like I said he's never said anything to me about my squat form. On the other hand, my snatch form is a whole other story. Again, he's never said anything about my OH squat position when recieving the snatch.
He responded to my email with a one liner about making sure my knees track my toes but then went on with a whole paragraph on stretching my squat position on a daily basis. So I am going to assume from that respone that he thinks this is a flexibility issue with me.
