This kid is working on his legs with a grueling bungee workout with his personal trainer. Unfortunately for the poor kid the trainer released the cord when it had the most tension on it and it rocketed into the back of the youngster. You can hear the terrifying sound of the cord whipping through the air until it collides into the back of the kid and probably gave him a pretty nasty welt. Part of me wonders if this trainer just hates this kid and maybe he did a “whoopsie,” and “accidentally” released the cord. As a trainer, how do you fight the urge to not do that every single time?
