2. No Meat Market
For some, going to the gym is their social hour, and time that they utilize to attempt to meet potential dates of the opposite sex. This can be a tad annoying for most women just trying to get their workout in and get home, without being rude or worried someone is following you to your car when you leave.
Working out at home alleviates all of those security concerns. No meat market, no creeping; except maybe from your family dog.
