I did my first spinning class yesterday, and it was quite possibly the hardest exercise I've ever done. I sweated buckets and couldn't actually keep the pace for the whole session because I thought my legs would fall off. Was this because a) spinning classes are high intensity, quality training for triathletes when time is tight b) it was indoors and so it was hotter and there was no scenery to take my mind off the effort - in fact I probably have cycled that hard but the wind evaporated the sweat away c) I'm so out of shape I should be ashamed that all the other women were so much fitter and stronger than me that they barely glowed and carried on chatting the whole time! Get out on the roads and stop fannying about with girly classes ???
