Hi there. I'm new here. Sorry for any typing errors as I'm on my iPhone. Anywho I have always just loved cycling for fun but last year I got quite ill and I've gone several stone underweight. I'm just starting to gain a little back now through eating but I'd love to cycle again. From your experience would this be advisable? I was planning to start slow for short gentle durations. Also is there any particular method to gaining weight or muscle through riding? Thanks
