The place I swim is offering a swim/gym membership at the moment which seems quite good value, but I have no idea whether to go for it, and if I do, what to do. There are no classes, but I think it has the 'normal' range of machines.
I have a funny fitness profile I think — I walk a lot, and do a performance sport that means I have strong legs and do bursts of intense exercise (like 90 seconds hard work then stop) and I used to play squash until the colleague I played with changed jobs. But I think I might be quite unfit in other ways — I can't do press ups for example, I just can't work out which muscles I need to use, or if I even have the muscles there... 
I've never been to the gym, but think I'd like to try to get myself fitter across the board.
I tried running, but absolutely hated running on pavements, but that is at least partly because I'm self-conscious about bumping into people and it's usually dark and cold (and when it isn't dark and cold I'm allergic to pollen!) so running on a treadmill might not be so bad.
Or home videos? This is a bit of a ramble, but I basically have no idea what I'm best to do!
