"Showing off his hula hooping skills and jump roping abilities, Dallas Cowboys running back Felix Jones broke a sweat Thursday afternoon at Bebensee Elementary School.Jones was working out with fifth graders from the school, as part of an NFL PLAY 60 event to encourage children to have at least 60 minutes of physical activity every day."Like my dad told me, your body is a vehicle," Jones told an enthusiastic student body. "You have to fuel your car properly and treat it like a super-duper race car. You need to eat right and exercise, and your body will grow big and strong."After talking with the students about maintaining a healthy lifestyle, Jones met with media members, addressing everything from the event to his weight and the potential NFL lockout."
