Choose your tier and hang from the bar with an underhand grip, arms fully extended. Pull until your chin is clearly over the bar, lower under control to a dead hang, and pause before the next rep. Repeat for max reps.

One-second dead-hang pause at the bottom of every rep — no kipping or swinging. Chin clearly over the bar at the top. Declare your tier before starting; most reps at your tier wins, and a higher tier always outranks a lower one. D5 (Weighted Chinup) is scored by added weight instead of reps.
