So where a traceur might approach an obstacle with complete intentions of going over, under, around, or through it–to be free and clear of it–a ptosser will approach the same obstacle and utilize it to perform some exercise.

In fact, the only similarity is in that in each activity, running and spontaneity are involved. With ptossing, the goal is to maintain constant movement for purposes of elevating the heart rate, and the performance of advanced bodyweight techniques to develop high strength-mass ratio; the whole essence of ptossing exists to offer participants a way of achiev
