Keep at the trainer. It won't get any easier but you will get fitter than if you were not riding.
I may moan about the weather over here but if I put my mind to it- I can ride in rain- and wind- and cold. One thing i won't do though is get on a trainer. Spiinning at the gym is bad enough for me. It does my brain in and I do not have the resolve to use one. So well done on riding the trainer and you never know- You may enjoy it-----Eventually
