Big changes from one race to the other in the same meet = nothing greatly positive is going to come of it. Judging from your other videos, you’re running tight. How much is ‘fixing’ it going to improve your 60m? Probably not as much as you’d hope–maybe a tenth at most. More importantly, it’ll keep you healthy, make sure you don’t burn out during a 100m/200m, and help you continue to improve.
