A dilemma

So I did this class at the gym today called 30-30-30, which is supposed to be thirty minutes of cardio, thirty minutes of strength, and thirty minutes of abdominals. Except it's an hour-long class. Which, um, yeah. Maybe math isn't their strong suit.

However. This is a good thing for me because I think if I had to do a half hour of stomach crunches I would die. The 40-10-10 formula we ended up doing was just about perfect. Although I got totally lost in the dancing/aerobic portion, especially on the spins, when I kept turning in the opposite direction of everyone else and nearly running into the more coordinated members of the class, I felt proud of myself for really holding my own in the strength portion. Maybe all the swimming has actually done some good. Who knew?

But that's not what I wanted to talk about. I wanted to talk about glasses. Since I'm new at this, I'm trying to watch the teacher like a hawk. But I leave my glasses at home, so that's out of the question. I find myself squinting at her, trying to see which leg is going where, and combined with the fact that it's hard to decipher the Spanish over the thumping music, I have several strikes against me. This happens even in a totally silent room, during yoga class, because the lights are dimmed and the instructor is a native Portuguese speaker so his Spanish comes out lovely and soothing but very hard to interpret.

What do other, non-contact wearing people do? I don't see anyone else wearing glasses, nor do I think it would be advisable (they'd either fly off during a spin or get crunched by the floor or my kneecap during a yoga position). And I can see more or less OK. It's not like I'm running into walls.

I should probably put myself in the front of the room. But that would mean I'd be more visible to other people, other people who, take my word for it, actually know what they're doing.

Is there a solution I'm not thinking of?
