It's a sort of physical activity that is like gymnastics but with freedom ofmoves.
Free running is a physical art, in which participants (free runners) use the urban and rural areas to perform movements through its structures focused on freedom and skill of movement. It includes tricking (flips, kicks, and twists), creating an athletic and aesthetically pleasing way of moving.
Free running and parkour are not actually the same but with aesthetic similarities. Parkour as a discipline comprises efficiency, whilst free running embodies complete freedom of movement.( Parkour means to try to move from on place to another in the fastest and most efficient way ... may be like NINJA)
