Dan Hardy smashed American fighter Rory Markham at UFC 95 thanks to his awesome punching power. This move has helped him develop that and if you want to build serious strength, drop it into your workout in place of one of your normal triceps moves.

Pick up a copy of the June 2009 issue of Men's Fitness (out on 22nd April) for Dan Hardy's full circuit. It's one of the toughest we've ever had in the mag and, if you can handle it, will get you ripped in a month. We'll also be sticking up a video guide to the workout on the web.
