Extreme Conditioning is a Tier 3 perk in Call of Duty 4: Modern Warfare, Call of Duty: World at War, Call of Duty: Black Ops (Nintendo DS), Call of Duty: Modern Warfare 3 and Call of Duty: Black Ops II that doubles the user's sprint time. This perk was replaced by Marathon in Call of Duty: Modern Warfare 2 and Call of Duty: Black Ops. Extreme Conditioning does not increase the sprinting speed of the player.

Call of Duty 4: Modern Warfare Edit

"Sprint for longer distances."

— Perk description

Call of Duty 4: Modern Warfare
Unlocked at	Level 1
Console codename	longersprint

This perk allows a player to gain a significant field advantage, such as reaching sniping points or objectives before the other team. Sprinting longer or more frequently disrupts any opponent trying to gain a long range firing advantage. This perk can also be considered as a fallback when being chased or ambushed, sustaining the sprint to take cover and regenerate health.

Combining this perk with an M21 or P90 makes the player sprint for much longer, but this is now only possible on the PC version and Wii version as the Xbox 360 and PS3 versions were patched to remove this bug.

Call of Duty: World at War Edit

Extreme Conditioning is exactly the same in this title as it was in its precursor. Like its Call of Duty 4 predecessor, it is often beat out by more commonly used perks such as Steady Aim and Deep Impact. Extreme Conditioning in World at War is vastly superior compared to the Call of Duty 4 perk. The reason behind this is that the maps in World at War are usually three to fives times bigger than Call of Duty 4, making the doubled sprint time very helpful to people who tend to favor using SMGs on bigger maps (like Cliffside) allowing the player to close the distance against people trying to snipe.

Call of Duty: Black Ops (Nintendo DS)Edit

"Sprint for a longer duration."

— Create-A-Class Description.

Extreme Conditioning makes a return in Call of Duty: Black Ops II as a Tier 3 perk. Like previous titles, the perk allows the player to sprint for longer periods of time before having to stop. It is available as soon as the player can customize their class at Lv 4.

Unlike the previous Call of Duty games, this perk does not include a Pro upgrade, along with the other perks in Call of Duty: Black Ops II.

Trivia Edit

• In Call of Duty 4: Modern Warfare and Call of Duty: Modern Warfare 3, the perk has an image that resembles an emergency exit sign.
• A typo appears in Call of Duty: Modern Warfare 3 in which once the first stage of the challenge has been completed on the screen it will say "Extreme Conditioning I: Sprint 0 miles". It should be just 1 mile.
• In Call of Duty: Modern Warfare 3, Extreme Conditioning can be paired with the USAS 12, MP9, or Skorpion (which gives a unique 75% increase in sprint duration) for 14 seconds of continuous sprinting.
