Extreme Conditioning

Extreme Conditioning is a perk in CoD4 Multiplayer and it is available from the start and is the 3rd tier perk in the standard Assualt class.It allows the palyer to sprint for longer distances, which is useful in Search and Destroy and for SMG users.It is an unpopular 3rd tier because many consider Martyrdom and Deep Impact the only good perks for a non sniper in the 3rd tier. When players can create a class, they ussualy switch out Extreme Condiotioning for Deep Impact.
