...that it's [awful] . Backyard wrestling videos are stupid. The kids in them know nothing about wrestling. They just hit each other with weapons and severely injure each other. They've had no training. Sure, they say they spend hours practicing. But, if a kid spent hours practicing football, and yet had no training whatsoever, he'd be killed. They might as well be practicing with assault rifles. Sure, I'm in a backyard wrestling fed. But me and my frineds do it for fun. We use fake weapons (meter sticks, shoes), we use a trampoline, we do simple moves, and, if we mess up, we stop. We've had very minor injuries (cuts, bumps on heads), so we learn from those mistakes. We've never doubled an injury. The kids on these videos wrestle on concrete and dirt, they use the trampoline to do backflips onto people, and, when someone bleeds, the other guy tries to open the wound further! Not worth anyone's money.
