Wanted opinions on bent drag knee from push to plant. I just had a discussion with a couple of guys about this. The purpose of the knee staying bent was to prevent stress on the back according to one of the guys. Obviously, we want it bent out of the sprinters position to get max push but does it stay bent to finish? Most of my kids keep it bent without me telling them. I certainly makes sense to me and if it prevents an injury I want to make sure we all do it if you know what I mean!
