This devilish workout from PT Alex Isaly is a killer. Start with the heaviest weight you can and power your way through the sets with a steady tempo. Get to failure? Drop to a slightly lighter weight and continue on. If you get to the final set of 6 and feel as though you can continue, keep repping until you can rep no more. Enjoy your DOMS.
