Go bowling: Bowling is a fun pastime for people of all ages. Even abuelita can come along. Bowling won’t burn as many calories as dancing or swimming, but you’ll be picking up an 8 lb. ball and working muscles that don’t get used every day. You’ll also be flexing and stretching as you try to knock down those bowling pins. Just steer clear of the greasy, fat-laden snacks at the bowling alley.
