Cycling-Related Strength & Conditioning

If your training isn't strengthening your legs, then there is something seriously wrong. It's QUALITY time, not quantity. Get to the hills and rep pushing the gears. There are a heap of leg strengthening ride exercises on the Bike Radar site. It pays huge dividends.

I'm baffled... and slightly aroused.

I see where you are coming from Bigtwin, but if you have a weakness with the hamstring/s (for example) and cycling is aggravating it, you would not benefit from churning big gears, or mashing up hills?
Changing the training regime will help to train the muscle in a full range of movement, and in some cases, iron out the weaknesses that are caused from not fully extending and flexing the muscle. This is very common amongst cyclists.
Good luck STE5.

Nail on the head.

My hamstring issue was caused or at least aggravated by hill reps.
