A forward roll, or roulade (roll) in French, is a parkour and free running technique used to land safely out of a drop from a high object. They allow the force of the fall to be distributed over a larger surface area to soften the fall and prevent injury. Rolls also allow forward momentum to be maintain, which enables a traceur or free runner to stay in constant motion. The roll is identical to kaiten or "breakfalling" used in judo, jujutsu, aikido, etc. The roll is often stressed as the most important technique to learn in parkour.
