If I run more she knows it because it is too hot when she tries to use the treadmill. Then she justs hits the power buttons. Ah well. Great job on the badges. Keep it going.
Shoot there is an easy solution ... just mount a fan on the handle bar of the treadmill that comes on automatically -or- better yet, get a BIG one that mounts behind and you can tell her the exercise goes better if she has a "tail wind"
