I’m pretty sure that if I do a little leg work (pun intended) I could find the answer to my question. Anyway here it goes, lately when I do heavy squats 1-3x10 my weight seems to shift forward to the balls of my feet/toes. Are my calves too tight, are my hams to weak. I’m guessing it’s my hams as I did GHR’s for the first time a few days ago and shamefully I could barely perform 3 with anywhere near decent form. Thanks for the responses in advance.
