</>What does Cardio Day (Infinite Stamina) do?
Remember when you used to get tired after sprinting for three seconds? Remember gasping for breath while a ghost casually floated toward your exhausted body? Those days are over. Cardio Skip Day gives you infinite stamina. Sprint forever. Jump repeatedly. Run circles around monsters who frankly seem disappointed in your lack of athletic realism. Your character now has the cardiovascular system of an Olympic athlete crossed with a car battery. Scientists are baffled. Monsters are annoyed. You're just vibing. No gym membership required. Side effects may include forgetting that stamina management was ever a game mechanic.

</>Common questions about Cardio Day (Infinite Stamina)
What does Cardio Day (Infinite Stamina) do in R.E.P.O.?
Cardio Day (Infinite Stamina) is a R.E.P.O. mod from ProjectMods that gives your character unlimited stamina. It disables R.E.P.O.'s per-physics-tick stamina drain at the source by flipping the game's own internal skip-drain flag, then it watches the energy value every frame and snaps it back to full if anything else (upgrades, traps, scripted events) tries to lower it. The result is that you can sprint forever, jump as often as you want, and chase or flee from monsters without your character ever stopping to wheeze. When you toggle the option off, Cardio Day cleanly restores normal stamina behavior, so nothing is permanently changed.
Is Cardio Day (Infinite Stamina) free?
Yes, Cardio Day (Infinite Stamina) is free to download through ProjectMods, the community-first game modding platform and desktop app for PC. ProjectMods supports 400+ games including R.E.P.O., Lethal Company, Content Warning, and PEAK, with a generous free tier covering hundreds of mods and an optional premium tier for the full library. You don't need to pay, sign up for a subscription, or unlock anything to use Cardio Day specifically. Just install ProjectMods, find Cardio Day in the R.E.P.O. mod list, and click install. The mod itself, the launcher, and automatic injection are all included in the free download.
Does Cardio Day (Infinite Stamina) work in R.E.P.O. multiplayer and co-op?
Cardio Day (Infinite Stamina) is a client-side R.E.P.O. mod from ProjectMods, which means it changes how stamina works for the player who has it installed. In co-op, only the host or the players who have Cardio Day enabled through the ProjectMods desktop app will get unlimited stamina; teammates without it will still drain normally. R.E.P.O. lobbies are usually played with friends, so the simplest approach is to share that you're using ProjectMods and let anyone who wants infinite stamina install Cardio Day on their end. The mod does not force anything onto other players' clients.
How do I install Cardio Day (Infinite Stamina) for R.E.P.O.?
To install Cardio Day (Infinite Stamina), download the ProjectMods desktop app from projectmods.io and let it auto-detect your R.E.P.O. install on Steam. Open the R.E.P.O. game page inside ProjectMods, find Cardio Day in the mod list, and hit Install. ProjectMods handles the injection, the loader setup, and the version matching for you, so there's no manual file copying or DLL dragging. Launch R.E.P.O. through the ProjectMods launcher with Cardio Day toggled on, and your stamina will stay full from the moment you spawn. Toggle the mod off any time to return to vanilla stamina behavior.
Can I still take damage or get caught by monsters with Cardio Day enabled?
Yes. Cardio Day (Infinite Stamina) only affects the stamina/energy system in R.E.P.O. It does not make you invincible, faster than the game's max sprint speed, or immune to traps, falls, or monster hits. You can still die, get grabbed, get downed, drop loot, and lose runs the normal way. What changes is that you'll never be the slow teammate who runs out of breath at the worst moment. If you want full protection, ProjectMods has separate R.E.P.O. mods for health, damage, and movement that you can stack alongside Cardio Day from the same desktop app.
