The Glob is the end of a York 60lb globe dumbell which was coined as a feat by Chris Mathison and Jedd Johnson, who lift it Blob-style by spanning the top. The GlobTop (name produced with permission of Chris and Jedd) is designed to emulate this feat in a loadable fashion. It's certainly a challenge!
