I'm going to post this in the road forum because you guys/gals give great feedback....I became really busy with school and halted my XC season so now that I'm getting back into training I'm going to focus my efforts towards cross season. I need a descent amount of upper body strength, but I want to keep my weight down so I don't have to go through the effort to lose weight come next XC season, so my questions is: How do I lift weights in such a way to build strength but not add weight? Should I be doing low weight and high reps? Or maybe low reps but high weight?? Any help is appreciated
