Freerunning has a distinct difference from Parkour. Freerunning evolved as a more expressive form of Parkour, an art form that is primarily about moving through space with the least loss of momentum. Freerunning has a personal dimension as well, insistence on moving forward not backward. Aesthetics are important to freerunners as well. Not surprisingly then then, freerunning is becoming integral part of the gaming industry and college clubs are ccropping up. This kind of freestyle exercise embraces not just the mechanics of training the body but includes the physical risk and mental challenge of pushing your body beyond it's limits.
