no it wont! just cycle through that rain, wind and snow and you'll get fitter.. IMO trainers are overrated
Well, yes it will. Trainers absolutely have their place. Just going out and riding in any weather isn't always going to be conducive to good training. Not to mention the fact that a trainer or rollers makes it vastly easier to concentrate on specific areas of your riding. I.e. Spending an hour at 100+ cadence, or sitting for 20mins in sweet spot power, or just spinning your legs over. Those things are a hell of a lot more difficult to do on the road than they are on a trainer.
