Combat moves and the conditioning exercises that go with them never make for an "easy" workout which means that if it's easy you want then this ain't the workout you're looking for. The Ultimatum takes you through one exercise after another, adding load upon load until your body aches and your abs shout "enough!". Don't listen to them. Go to the very end and do not stop. If anything, add EC on top of everything else.
Extra Credit: 1 minute rest between sets.
