Ride a bike

Hmmmm... what is the best fat burning supplement. I have no idea. Because so far, I don't need to use any supplement to burn my fat :D I ride my bike to burn some of my fat hihihihi... With my old bike, I used to ride two or three times a week for groceries. But now, almost every day I am riding my bike with Jason sitting on his seat behind me. He likes it very much, only now I have a problem. Jason doesn't want to ride his own bike. anymore. He  tends to say:  "I get tired when I ride my own bike."
