Weight / Fat loss

Yes think I may go use scales somewhere else at some point. Also thinking of joining the gym again, probably the gym group, do any of you guys using weights do so at home maybe without even using weights? I'd love to do something like that over joining the gym.

Also are there other exercises like chin ups you can do without a chin up bar?

I do 140 push ups a day. 35 at a time, randomly throughout the day.
I have a nice doorway I can do pull ups on. 10 at a time.
I also have a swiss ball for core work.

The press ups are the only bit I really stick to though. I find i work harder and in a more focused fashion if I drag myself to the gym though. Doing bits at home never nets the same workout.
