This is what happens when two of the world’s funniest people buy every fitness machine available on late night TV.

Kevin Hart invited Bill Hader into “his” home to raise their heart rate on various awkward devices. They get into it while exchanging celebrity impressions of varying skill such as Alan Alda, Denzel Washington and The Rock.

This video comes via Hart’s hilarious What The Fit series on YouTube which also features Conan O’Brien, James Corden, Tiffany Haddish, Khloe Kardashian and Leslie Jones.

Hart does something like 1000 sit ups and push ups every single day. The dude is in decent shape. I’m thinking none of that is due to shake weights, the ultimate prank on anyone who uses them.
