Weight Room/Cardio - Why do I have to wear a full-length shirt?

Bare chests or wearing only a sports bra pose a hygiene issue.  Sweat and bacteria from all the exposed skin can be transferred to the equipment and left for the next person who comes in contact with that machine.  In addition, some patrons may feel uncomfortable exercising in a facility with users who are not fully clothed.  We want the Recreation Center to be a welcoming and inviting place for everyone.
