Scary Face strikes spin class again

There is a woman who goes to my gym that makes this face while she's working out:It frightens me. Sometimes she sticks out her tongue and wiggles it. And she goes to about half the classes I go to...

I complained about her to a friend, and she informed me that Scary Face has lost over 100 pounds! Apparently she was the winner of some contest at our gym ... and apparently I am an insensitive jerk.

I am very impressed, but when Scary Face happens to be on the bike across from me at spin class, I tend to forget about how hard she must be working and instead become distracted by the facial calamity I can't help staring at.

Is it too much to ask that facial control be part of gym etiquette? I often make scary faces during spin class sprints and dancer's body squats (minus the wiggling tongue), but I courteously lower my head so no one has to witness the hideousness. I feel the same way about grunting. My high school gymnastics coach once told me not to be afraid to make noise while lifting weights because I'm a girl. I responded, "Ew! Neither gender should grunt like that in public!" (in my head). Let's save the strained noises and expressions for our home gyms and bathrooms, please.
