weight lifting workout routines

What would be a good sprinter weight lifting workout?

Does anyone know what would be a good lifting routine for a sprinter that is doing 100m and 200m dashes? And should i focus more on lower body lifts or upper body?

This is what my track team does.
We do dead lifts 3 sets of 3 lifts
we focus on the hip flexers(sp)
calf raises and the opposite
we bench press,
and on the bench press we also do squats
we jump over benches that are in a row to work on explosiveness.

atleast thats what i do
