How does it take?
My warm up is around 1200 – 1600m runing, skipping etc.
In that I include drills, joint rotations, runthroughs. I do hurdles drills at the end. I than do specific stuff, depending on the event. IE Starts for sprints and hammer for hammer.
I tend not to do static stretches. I tend to do active stretches if I do any.
I allow my athletes to do a minimal amount – more for psychology or anything else.
My warmup takes 60 minutes.
