After 3 full 3-week-cycles, i am doing just 1or 2 weeks little training with weigth 3x12,techniquel sprints and maybe 1jog…

So, what do you think about it for competing 60m indoor?

PS: I am not doing tempo; that comes in a similar plan for outdoor season. And then i wanna also do plyometrics(dont wanna do them now,bc of my back problems…)
