11.Martial Arts
Get into shape while you learn how to defend yourself. It helps you focus your attention and may keep your brain sharper than sports like running. And “light” contact types like karate, judo, and taekwondo are pretty safe, compared with other sports, as long as you train with a qualified instructor.
12.Zombie Runs
You say you’ll only run if something’s chasing you? Well, that can be arranged. Zombie courses often have obstacles to get over or creeks to run through and may run on mud-covered trails. And if that’s not enough motivation, members of “the living dead” watch from secret locations and jump out to steal your vital organs (in the form of flags) as you try to finish the race.
