This workout actually starts once you're in the double digits. In a sense, the 3's, 6's and 9's are a buy-in. So wasting too much energy there will leave nothing for the later, more challenging rounds. Be smart and start smooth, get comfortable with whatever pace you have. The limiting factor is really only the push jerks, so scale accordingly to where you might conceivably be able to remain unbroken once you get overhead. Start smooth, keep the pace, and push through. Test your stamina and see how long you can hold onto those push jerks. This one's designed to be challenging, so rise up to that challenge.
