Cycling training with gym equipment

[MatchDave]

My current gym doesn't have spin classes, but previous gym in a different city had a couple of quite good spin classes weekly. What made them good was they were led by cyclists - either roadies or triathletes - so what we did in those classes primarily was based on stuff we do on bicycles. Other spin classes at same gym were led by non-cyclists, and they were awful.

So if you can find spin classes led by genuine cyclists, can be a useful off season addition.
