Despite the great weather for outdoors here at the moment I am sticking to the trainer as well as am 7.5 months pregnant and being a bit precious about falling off outdoors. I have to say that it is a hell of a lot more fun as of a week ago when I realised the trainer resistance was set to HIGH instead of low. I couldn't work out why I could not keep my HR down on the lowest gear . I'm only doing 30 - 50mins at a time but hope that by the time I get outside again it will be easier to go longer in each session.
