Looking to burn some more calories? Try this shocking method.

This is a great video in which a guy doing pull-ups suddenly finds energy and strength he didn't know he had when someone else threatens to tase him in order to prevent him from slowing down.

One second he's the scrawny nerd in gym class getting plunked in the head during dodgeball. The next he's Sylvester Stallone training in the Russian snow in Rocky IV.

This is pure genius. Like it should be an infomercial for a product we'd never buy type of genius.

There have to be other ways to get people to complete more pull-ups, but short of a naked woman dangling lazily above the bar with with whipped cream dripping in slow motion off her chest, we're not sure what else can compete with this.
