Respecting one's health and physical well-being was one of the foundations of the group. If any member hurt himself during or after the execution of a movement, the movement was deemed a failure. A movement executed only once was not considered an achievement; only with repetition was the challenge complete. Every movement had to be repeated at least ten times in a row without the traceur having to push his limits or sustaining any injury. If any mistake was made by any traceur in the group everyone had to start all over again.
