Maximise exercise benefits After 10 months my commute has gotten to the stage where it's quite easy and I'm looking for ways to maximise it as a workout and hopefully benefit more muscle groups. Currently it just seems to work my thighs.

I don't have time to ride for fun, but my commute is an hour each way which seems plenty. If I wanted to spend more time I could do a stomach/calf workout instead.

I would have thought it would use the calves but it doesn't seem to (I don't feel any burn in the calves).

Ideally I would like to work my abdominals while riding. Is there any way I can do this? I have thought perhaps purchasing a weight belt so my stomach has something to push against but I'm reluctant to spend the money for something that might be useless and I'd have to wait a month for shipping.

So my question is, is there a way to benefit more body parts than just the thighs while cycling?
Vary your cadence during your commute.High cadence (90 - 110+) will train the heart. Low cadence (60) in a Higher gear will give your Legs Back and Arms a good workout.Dont forget to do some regular stretching esp on those big glutes.
