Exercise is so much easier if you can incorporate it into your daily life, but we're too afraid of a little sweat and stank that we huddle in our cars and get fat, fat, fat!
Human beings don't get as smelly as quickly as we tend to think. Yes, running on a treadmill for 30 minutes will make you stinky, taking 30 minutes to walk your 1.5 miles to work, not so much.
The obesity epidemic is caused by many factors, but our fear of sweat doesn't help much. I'd rather be smelly and thin than smelly and fat. I mean, when you get so fat that your dead skin cells collect in your rolls and start rotting... that has GOT to smell worse than someone who took a bicycle to work.
And in the world of dating I'm pretty sure the athletic girl sans make-up with her hair in a ponytail and a runner's glow beats out the fat chick with too much make-up and perfect hair EVERY time.
Lose the make-up, let your skin breathe!
Embrace your sweat, it turns a fat girl into a cute girl and a cute girl into a hot girl.
