I am a jumper who is about to compete for my Division 1 university and I need help on the correct lifting for Offseason training. If I wanted to lift three times a week, with a focus on legs on Monday and Friday, and Upperbody on Wednesday. How many sets and reps should I do and which exercises?
As I can see, it’s your first post here.
You’d better use the search button first, find some useful information in here and then come back to this thread with the best first draft you can.
Otherwise, I doubt anyone can, or is willing to answer such general questions…
Also, more specific information (e.g., training age, height, weight, PBs perhaps in the weight room, etc) MIGHT help 
Good luck!
No more “feed me” posting…this is a warning.
