OK, first things first, I'm not in great condition. I'm 47, obese, bordering on morbidly obese (but was properly morbidly obese until last year, when I lost four stone - mostly on the BSD), and have severe arthritis in both knees. I walk about an hour a day with my dogs, and a few weeks ago started swimming a couple of times a week, which I'm loving and building up gradually. I've also just joined got a week free trial pass with the gym where I swim. I had the so-called 'induction' today, which consisted of a pleasant-enough youth showing me how to program the exercise bikes, waving his arms at the rest of the equipment and saying 'they're all the same really', and doing something similar with the resistance training equipment 'bands??'
Can any of you lovely people give me some sort of suggestion how to get started with all this stuff? How long to people spend on each thing? I'm particularly interested in building up my muscle strength to help with the arthritis, so if anyone has any suggestions for that I will be eternally grateful
