The next time you head to the gym or a yoga class, you may want to think about taking along your own floor mat. Sure, the gym's rubber or vinyl mats provide the same cushion, but they also are potential incubators for bacteria and other germs.

Many gyms and aerobics classes provide mats for students. But think about it. Dozens of people use the mats each day with sweaty hands and feet. Although many gyms ask patrons to wipe equipment and mats off after each use, many people don't.

Experts say viruses and bacteria can survive for up to two hours on the surface of everyday objects such as door handles, countertops and, yes, your exercise mat.

The gym or workout room is the perfect (hot and humid) environment for harboring germs. To fight this, some facilities provide anti-bacterial spray or cleaners for members to clean the equipment after each use. Cleaning and sanitizing procedures for yoga mats vary. Some gyms spray mats daily, and others spray daily with a weekly washing. Ask the attendants how often the mats are sanitized.

If you aren't sure about your gym’s cleaning regimen or you want to take additional precautions against spreading germs, you can:

• Take your own mat
• Take sanitizing wipes and clean mats before using them
• Wear gloves and socks
• Take a long, thick beach towel to place over the mat
