I went to a taster class yesterday and although I ache I think this would be good for me. For anybody who has done this I wonder if you could help me with how often I should do it. The gym sells packs of either one class a week two classes a week or unlimited classes. I feel that I should do it at least three times a week but as I have been away from exercise for so long I wonder if that is too ambitious. For anybody who does this does the jump from two to three classes a week make that much difference? Thank you
