I want to get peoples' opinions about how to best improve strength and muscular endurance during the off season. My weakpoint is climbing and pedaling on the straight parts of mtn bike races... So I'm wondering if I should concentrate on weight lifting and lay off the biking during most of the winter months or if I should forget about the weight lifting and focus on high resistance pedaling....or I've also heard that maintenance (low intensity endurance) during the winter months is the way to go...? -Thx
