Watching the Food Network while you’re on the treadmill is counter productive. (Just watching the amount of butter Paula Deen uses is clinically proven to make you fatter.) That’s why you gotta bring your MP3 player along so you can listen to your workout music and get pumped. Of course there’s always the question of what to do with it once you’re at the gym. You can get one of those arm bands and look like a meathead. Or you could keep it in your pocket and risk having it fall out and break. Or you could try secret answer number 3, the Underfuse Performance Pocket. It’s an iron-on pocket designed by product designer/engineer Tal Cohen that bonds to workout clothes and holds your important stuff in place while you workout. Get your own Underfuse by contributing $8 on Kickstarter.
