trackstar88 - what is your current weekly set-up?
If you are doing track and weights on the same day you will have to be very careful about managing CNS stress. I get the feeling that you’re the sorta guy who loves to train, but always be mindful of how much your body can handle. You don’t wanna go into the gym with your CNS trashed from a big track session (even if it was the day before) and do yourself an injury lifting weights. This is a particularly big concern with powerlifting and shoulder/spinal injuries. I’ve had spinal nerve compression from trying for too much on the snatch after a big speed session and by God did it hurt!
Remember - whether it is for maintenance or power work or whatever, weights are a secondary activity to sprinting, and if you feel like doing a gym session is gunna jeopardize your next sprint session, you’re best to leave it alone. But I’m sure you knew that.
Good luck!
