"BASIC SKILL. Rule #1 for survival. If you run out of Stamina, that's it. Can't fight, can't run away. You're done."

Cardio is a basic skill that every survivor has. Improving it increases the character's maximum Stamina, allowing the character to run and fight longer before having to rest. At level 7, Cardio unlocks two Special Techniques.


"Build up your Cardio the old fashioned way: run. A lot."

Cardio can be trained by sprinting. It is unconfirmed whether rolling/jumping/vaulting over obstacle improves Cardio.

The following traits reduce Cardio XP gain rate by half. There is no way to increase Cardio XP gains.

  • Asthma Attacks
  • A Pack A Day
  • Loved Movies

Comparison - Sprinting with and without a bag

Comparison - Sprinting with and without a bag

  • If the player has abundant snacks, they can be used to accelerate training, i.e the characters don't have to wait for stamina to recover to continue sprinting.
  • (Unconfirmed) Cardio seems to improve slower if the character sprinting is encumbered or is carrying a rucksack. A visual comparison is shown in the image, for a level 1 Cardio character sprinting a full lap inside the fences of Snyder Trucking Warehouse, while constantly using Snacks when Stamina is depleted.
