I've been pondering this since I've been in a new lifting plan this fall. The answer to this question may have 2 different answers depending on whether it is a sprinter or jumper, but primarily my question pertains to jumpers.
Is upper body strength necessary at all for a jumper? Is it necessary to lift upper body, if so, how much of a role should it play in a strength program?
My current plan calls for 2 days of upper body and 2 days of lower body lifting. Reps range from 12 and work there way down to 3 on about an 8 week cycle (however, probably at least 4-5 weeks are 8+ reps). I like the weight I'm at and am concerned about gaining more weight, especially upper body.
Would I be better off not lifting on the upper body days? Generally, I try to pair my high CNS days with the lower body days and try to go lighter on the upper days (low CNS days).
