video of my start, new 40, any coaches in Portland, OR?

thanks and I’ll do those starts. I’ve heard a lot of recommendations of getting stronger in the weight room now…does anyone have a metric they have seen/coached their athletes to that does seem to correlate with a better start?

My back squat(full depth) is 310 for 1 rep. My Bw is 190. How much higher does it need to be? Should I squat only 3/4 depth or jump squats instead…cause it seems that you never get the full squat angles when sprinting!
