Well, since joining this forum, I have learned a bit about weight training and women and cycling... and I understand now that it has a place (Thankyou people like Wahine, Hann and Andrea)

I do crunches (when I remember) to make my tummy stronger.

I have known for years that as we get older, weight-bearing exercise is increasingly important.
This is not always easy on a bike (depending on how you ride I guess) and certainly not as effective as something like low impact aerobics, or weights.

Having said that, I still stand by what I say every time this discussion comes up. If you want to get fit for cycling, you ride a bike.

My favourite discipline is time trialling, so I try to train smart. I am improving my performance in time-trials by the types of training rides I do.
I do my power-training on my time trial bike... so I do intervals in my biggest (or big as possible depending on conditions) gear - so my heart rate does not get really high, and the cadence is very slow but my legs get REALLY tired! I do hill reps on moderate gradient hills - seated and on my aero-bars...

I am not an exercise specialist, and maybe (probably, by what our experts have explained) if I had a gym workout I could improve my power output, but I don't have a coach/trainer with this expertise, and what I am doing is working for me.

And I think that is the key... experiment. Find what you like doing, what you have time for, and what you can afford.
(I like riding outside, I don't like gyms/ I have to fit my life around work, kids and the long drive to&from work - I don't have time to go to the gym / I can't afford to belong to a gym...)
