Terminology (parkour)

Name
Description
Arm Jump, Cat Leap, Cat Grab
 To land on the side of an obstacle in a hanging/crouched position, the hands gripping the top edge, holding the body, ready to perform a muscle up.
Cat Pass/Jump, (King) Kong Vault, Monkey Vault
 The ‘saut de chat’ involves diving forward over an obstacle so that the body becomes horizontal, pushing off with the hands and tucking the legs, such that the body is brought back to a vertical position, ready to land.
Dash Vault
 This vault involves using the hands to move oneself forwards at the end of the vault. One uses both hands to overcome an obstacle by jumping feet first over the obstacle and pushing off with the hands at the end. Visually, this might seem similar to the ‘saut de chat’, but reversed. Allegedly David Belle has questioned the effectiveness of this movement.
Drop
 Literally ‘jump to the ground’ / ‘jump to the floor’. To jump down, or drop down from something.
Dyno
 This movement comes from climbing terminology, and encompasses leaping from a position similar to an arm-jump, then grabbing an obstacle usually higher than the initial starting place, often used for an overhang. This movement is used when a simpler movement is not possible.
Gap Jump, Running Jump
 To jump from one place/object to another, over a gap/distance. This technique is most often followed with a roll.
Kash Vault
 This vault is a combination of two vaults; the kong vault and the dash vault. After pushing off with the hands in a kong vault, the body continues past vertical over the object until the feet are leading the body. The kash vault is then finished by pushing off the object at the end, as in a dash vault.
Lache, Swing
 Hanging drop; lâcher literally meaning “to let go.” To hang or swing (on a bar, on a wall, on a branch) and let go, dropping to the ground or to hang from another object. This can refer to almost all hanging/swinging type movements.
Landing
 Bending the knees when toes make contact with ground (never land flat-footed, always land on toes and ball of your foot, or whole footed).
Muscle-Up, Climb-Up
 To get from a hanging position (wall, rail, branch, arm jump, etc.) into a position where your upper body is above the obstacle, supported by the arms. This then allows for you to climb up onto the obstacle and continue.
Precision
 Static or moving jump from one object to a precise spot on another object. This term can refer to any form of jumping however.
Pop Vault, Wall Hop, Wallpass, Wallrun
 Overcoming a tall structure, usually by use of a step off the wall to transform forward momentum into upward momentum, then using the arms to climb onto and over the object.
Reverse Vault
 A vault involving a 180° rotation such that the traceur’s back faces forward as they pass the obstacle. The purpose of the rotation is ease of technique in the case of otherwise awkward body position or loss of momentum prior to the vault.
Roll
 A forward roll where the hands, arms and diagonal of the back contact the ground, often called breakfall. Used primarily to transfer the momentum/energy from jumps and to minimize impact, preventing a painful landing. It is similar to the basic kaiten or ukemi and it was taken from martial arts such as judo, ninjutsu, jujutsu, hapkido and aikido.
Rotary Jump, Rotary Vault
 Similar to a kong vault, the person dives and then rotates their lower body around the obstacle. Used for shorter to medium obstacles. For people who have trouble with kong vaults.
Speed Vault
 To overcome an obstacle by jumping side-ways first, then placing one hand on the obstacle to self-right your body and continue running.
Thief, Lazy Vault
 To overcome an obstacle by using a one-handed vault, then using the other hand at the end of the vault to push oneself forwards in order to finish the move.
Turn Vault, Turn Down
 A vault or dropping movement involving a 180° turn; literally “half turn.” This move is often used to place yourself hanging from an object in order to shorten a drop or prepare for a jump.
Underbar
 Jumping or swinging through a gap between obstacles; literally “to cross” or “to break through.”
Vault, Pass
 To move over an object with one’s hand(s) on an object to ease the movement.
Wall Jump, Tic-Tac
 To step off a wall in order to overcome another obstacle or gain height to grab something.
