While I was stretching at the gym today, I happened to notice the posters advertising the Group Exercise classes. In the poster, the instructor is smiling and so is everyone around her. I have never seen ANYONE smile while working out. EVER. While smiling does work out your facial muscles, that's no big help in the weight loss department. If it was, I'd be Kate Moss by now.
I'm always amazed at the advertisement ploys used. Smiling has nothing to do with working out. At all. I never smile while running on the treadmill for example. If anything, I frown. It's hard work running that last five minutes at an incline that practically requires hiking boots to maintain.
While I believe strongly in exercise, I'm also for truth in advertising and you won't see any smiles at the gym. If you want to see smiles, go down the street to the doughnut shop.
