At some point recently, some guy thought it'd be a great idea to stack nine dumbbells on top of one another so he could pound out some handstand push-ups. This won't give him any sort of better pump, but it did get him on a bunch of websites. Unfortunately, the internet opted not to focus on his display of pointless athleticism, instead focusing on the more useful athleticism of the elderly man in the background sinking free-throw after free-throw after free-throw.
Oh well, every once in awhile a plan backfires. Here's a bunch of other people who risked major injury and/or death to try and entertain you for about five seconds before you click on something else and forget all about them.
Splits + Overhead Barbell
Squats + Curls
Taking supersets to the next level. We wouldn't advise unless you got enough money saved up for a wheelchair ramp.
Tire Push Ups
It's all fun and games (we think?) until that workout stunt backfires. If you've never heard of Greg Plitt (RIP) feel free to check his Wikipedia.
Stomach Punch Workouts
Woman Press
There's got to be a better way to get a great view.
Anyways, don't try any of these at home, the gym, or at your home gym. Probably should've said that earlier. But, if you do, at least make some dough off them—don't just upload them to YouTube, for crying out loud.
