• Fat burning tends to occur after 30 minutes or more of moderate exercise. (i think that is around 60-70% of max heart rate or some such bollocks).

    Sprints/riding hard will tend to help with muscle building but you have to eat protein fairly quickly after wards (1 hour window of opportunity) for best results.

    Not sure of any cons to cycling every day. I got my bike at the end of June, having not cycled for over 10 years. Been doing 150-200 miles a week since then and have lost 3 inches from my waist, 2 from my chest and legs got bigger.
