My housemate has a treadmill and I don't mind jogging to work because I get to use the chemical shower before work,
Other than joining a gym (ew!) I'd only be getting that exercise.
Although my resistance for joining gym has to do with my previous weight and I may be less averse to it now I've lost some weight (why do they make it so hard for those with bad body images when its us who need it the most, I hate seeing toned people at the gym, why are they there, they are finished!)
