This is one way to get the gym all to yourself. A man working at a 24 Hour Fitness gym in Texas said he had to call another location for help when he was locked inside at closing time. Jonathan Santos said he encountered another employee in the locker room of the gym, located in Spring, just before closing and that the worker acknowledged his presence. However, Santos says when he left the locker room a few minutes later he discovered he was locked inside the business. He says he was trapped inside for about 25 minutes before he was able to reach employees at another location who then sent help.
