Five Ways "The Walking Dead" Demonstrates the Importance of Fitness

1. If you run out of ammo you better be able to swing something; katana, machete, baseball bat with nails in it, frozen turkey it all means upper body strength required.
1b. Carrying a baby. You could trying swinging the baby, I guess. But I doubt the baby would be for that.
2. Cardio. Cardio. Cardio. Walkers, marauders, wild animals (mostly squirrels it seems, but they can go rabid) and salesmen. They all still exist and you need to escape them.
