if you want to be the best cyclist you can be, the only off bike resistence training you need to do is some core work, and some stretching.

In my experience, lifting weights for your legs in season prevents you from doing the most work you can do on the bike, and actually hurts performance.

Some people believe doing some weight lifting for your legs off season has some benefit. However, more and more people are going away from weight training even off season. and there is little if any data to support resistence training helping road cyclists.

The plan I follow incorporates on bike resistence training in the base phase (stomps, power starts and muscle tensions.)

When I started working with my current coach and asked him for a good weight program for the Winter, his response was "I can make you look Buff, or I can make you the fastest cyclist you can be, which do you want?"
