Ben Greenfield explains a strength-training protocol performed on ARX equipment: a single set taken to muscle failure for roughly two minutes (extreme time under tension), performed for essentially every major muscle group. He emphasizes observing real-time strength changes within the set and prefers this single-set-to-failure approach over multiple sets/reps with rests.
