I have been having trouble getting some of my high school male sprinters to get full extension from the shoulder through the toe when driving out of the blocks. I have one athlete in particular who has run some good races for me (10.8, 21.9) but still has improper starting mechanics. This particular athlete seems to almost lift up with his hips as he is driving out causing him to be hunched over 3-4 strides into the race. I am not sure what to do to fix this problem…does anyone have any good ideas to help train this mechanic? Furthermore, is there just some cue that I should be giving him that would help solve this problem?
stop trying to give cues and get them stronger esp in the post chian, most young sprinters cant get full ext bc they lack strength. some runners are quad runners which tends to hinder them from achieving full ext.
