I am a certified personal trainer, Wellness Coach, and Pilates instructor. I take Bikram Hot Yoga almost daily, and sometimes twice a day. That's a lot of time observing others' habits (and my own).
-body odor: if one doesn’t wear antiperspirant because of the aluminum and other chemicals, please use natural alternatives like tea tree oil wipes and salt sticks. They help with the odor in a natural manner. The same thing goes with foot odor. Wash down your feet or put perfume on them before taking off your shoes and socks for a mat class. Funky feet next to my head after a long day at work just drives me crazy.
-putting a yoga mat directly in front of others: when I teach Pilates, I am annoyed by people who place their mats directly in front of others because the person who got there first cannot see their own form and technique in the mirror.
-sweat puddles: if you create sweat and it stays on the equipment or any surface, be a buddy and wipe your sweat up thoroughly.
I hope this helps you, dear readers.
