The 443m Test

intermediate15 min~120 kcalForearmsBackCore

A 15-minute grip and back test built around the dead hang, the simplest honest measure of upper-body endurance there is. Three sets of a 60-second hang, hanging knee raises for the core, and three sets of pull-ups. Short, unglamorous and surprisingly hard to complete cleanly.

How to run The 443m Test

Hang with the shoulders active rather than fully slumped — think about pulling the shoulder blades slightly down. Take three minutes between hangs; grip endurance recovers slowly. Chalk helps, straps defeat the purpose. Track your best unbroken hang each week.
