Long story short. I've recently become addicted to racing and have good initial results. I dedicated myself to cycling and stopped lifting weights w/ my legs 8 mos ago. I lift upper body 2x per week and only high reps, supersetting different muscle groups to keep it aerobic. I've gone from 220lbs to just under 200 lbs in about 3 mos (6'3" and about 10% body fat), however my legs are half the size they use to be. I can climb much faster but feel my sprint is less than it use to be. If in a group sprint I seem to always finish in top 5 and have a couple second places but feel if I could sprint like I use to I may be taking the podium. At this point what would anyone recommend??? Should I start lifting legs again? In what manner? I've tried this once or twice on vacation and cannot lift the weight I use to and regradless end up with VERY sore legs the next few days and it limits any intervals or tempo riding I do on the bike. I know some people would say just practice sprinting but I'm not sure that this is the way to get best at sprinting. If I should stick w/ just on bike time how many and what types of work-outs should I dedicate to this? In Cat 5 this seems to make or break your finish and I just want to optimize my talent. I feel like w/ my weight loss and training I can hang w/ the group on 95% of races (even w/ hills) and would like to feel like Boonen nearing the finish line. If I'm near the front ain't nobody gonna beat me!
