Suckerpunch is a two-exercise combination workout that works all the major muscle groups used in combat skills and punching. This is a Level II workout which means it's perfect for those days when you just feel like maintaining what you have without pushing against all limits, but with just a little tinkering (like staying on the balls of your feet throughout) it can become a lot more intensive, very quickly. Cutting down on rest time will let you test your body's recuperative ability and cardiovascular fitness.
