This is such a cool concept!!Instead of using money to pay for your food, at this cafe in London's Covent Garden (my FAVORITE part of London!) called "Run for your Bun", you pay for your food by completing different exercises! Would you go?! I'd definitely go! Best kind of motivation right?! Plus, after you work out - you're not going to want that big greasy burger and waste all of those burnt calories! Win-win.
