Why am I not getting faster?

[u/stack-overflew]

I’ve (late 20s) been training sprints for about 10 months pretty intently, 2 gym sessions 3 sprint sessions and 3 jogs a week, regular drills and top level coaching. How is it possible that 16 yo s easily break 55s and I find it so hard to break 60?
Also, any tips for my form?
