Mowing the Lawn
It’s neither fun nor glamorous, but it is good exercise. As long as you're doing the pushing, the movement engages your chest, shoulders, and arms in addition to your legs. “If you really want to get your heartbeat up, try doing squats or jumping jacks after each row. Just be sure to turn the lawn mower off first,” says Rappoport. According to MyFitnessPal, a 180-pound man will burn more than 400 calories by pushing the mower for an hour.
