hiya, glad you've found that excercise is the best thing for depression. You could do a floor workout, all your actually trying to achieve is the release of endorphins and they will eventually come with any sort of excercise, so you could do an upper body workout sitting on the lounge floor. Alternatively you could try meditation, mediatating on running water ( as a subject, waterfalls etc) usually is a good thing for depression I've found , although if you have a littly they aren't always condusive to relaxing:)
