I have always lifted weights to stay in shape. I lift 3 times a week and try to ride on the other 4 days. Now that the weather is getting better I find myself wanting to ride almost everyday. Hard to fit in the gym time when I do this.

When I lift I only work on my upperbody. Chest, back, arms, shoulders, abs.

I figure that riding is good enough for my legs.

Will lifting have any adverse affects on my riding?

I would like to keep a little definition in my upper body this summer.
