As long as I am sane, I will never join a gym as long as I can't afford a house cleaner. Scrubbing my [hardly ever scrubbed] bathroom took two hours and countless calories. I am more sore than I ever would be going to a gym, and the level of disgusting in my bathroom is equal to, if not less than, what it would be at a public locker room.
On the other hand, I am slightly more likely to go to the gym than I am to clean my bathroom. The only reason it's so sparkly white right now is because my mom's coming tomorrow, white gloves ready (kidding, Mom!).
Also, I think I just acquired three different types of cancer from the assortment of chemicals I just inhaled.
