Your final strength test for the week is a 1RM deadlift. If you haven't yet memorized the warm-up for max testing, it can be found on Day 1. If you're not accustomed to testing your upper limits on big lifts, today's challenge might feel a little scary. But remember your commitment to this week's mission and try.
Although you should complete all circuits quickly, you can really go all-out during the second circuit. Complete all four rounds in the shortest amount of time possible. That means no rest, no water breaks, and no stopping unless your shoe is honestly untied. Don't stop until all four rounds are done!
