You know how greyhounds at the dog track run faster because they chase a fake moving rabbit? That might actually work for you too.
--Scientists at the Royal Melbourne Institute of Technology in Melbourne, Australia developed something called the Joggobot, which has basically the same effect as that moving rabbit . . . for humans.--The Joggobot is a specially-tweaked remote-controlled hovercraft that flies along with you as you run. You have to wear a T-shirt with a special pattern on it so its sensors can track you.
--You can either use the Joggobot as a companion, to run alongside you . . . or as a coach, who flies ahead of you, challenging you to keep up.
--For now, the team has only made an experimental version, and there's no word if or when this might be available in stores.
