I’m told this is called “Dub Step.”  Not sure if it refers to the dance or the music — but that’s neither here nor there.  What fascinates me is the superb muscular control this man has over his body.  If you’re not into what currently passes for popular music these days, you have the option to mute the sound.  He does arms like Rachel Brice, which in my book is a compliment.

See what you think.
