Yeah and maybe a swimming pool too?

I dont know your status but I work within the shipping industry and quite alot of our container tips take 3-4 hours. You havent said what you deliver so it might not be the case for you but can you not get stuck in with the unloading? I know your insurance doesnt cover you and all that bollocks that drivers normally come out with but thats just their way of shirking work.

If you drive a cab and pull a trainler maybe you could strap a bike to the back of it? I've seen that done before many time (usually for pub runs) but you can use it for exercise.
