I'm probably not the first bloke in his mid 40's to wake up to the fact I'm fat, unfit, slow and likely heading for heart attack territory if I don't take better care of myself. I'm 5' 11" slim build / frame, but currently carrying 18st so have a sizeable beer belly (although I don't actually drink - it is more likely the biscuits and poor diet). Having enjoyed a bit of running in my younger school days and feeling it is a kind of exercise I can do cheaply and easily (just pop on trainers, shorts and t-shirt) I wondered if you had any advice on how to get back into it? I appreciate I need to change my diet and will work on that, but should I start with walking first and see how it goes? Would running with this excess weight damage my knees or back? Any advice appreciated.
