I have a problem with my feet that means I can only walk very very short distances so I'm really struggling to lose weight or do any exercise at all. Can anyone think of any type of exercise I'd be able to do (anything beyond sitting all day, which is what I do all day at my work, I'd be happy with!). Swimming is the obvious one but I can't do this for other reasons. I just feel so unhealthy and losing weight seems like an impossibility.
