How did your training begin?

I had stumbled upon many videos of Russians, 3Run, The Cambridge Traceurs, and Yamakasi. Watching athletes perform such great skills caught my attention enough to lead me into pursuing the same movements. A friend and I begin practicing a great deal of push-ups, pull-ups, quadrupedal, and standing jumps. A year or so later, we then begin the movements we sometimes see in parkour today.
