Ready to feel weak? Check out this video of a baby named Jonas who, at age nine months, is already doing serious pull-ups on computer desk because he can.
Shortly after this video was uploaded to YouTube, the baby's father, Chuck Norris, came in and did 300-400 reps without stopping to demonstrate proper form.
Just kidding. If this were the spawn of Chuck, it would have mastered pull-ups at 2-3 months and started delivering roundhouse kicks to the face by now.
