High-Intensity Training did not start with Mike Mentzer. It was codified in the 1970s by Arthur Jones, the founder of Nautilus, who argued that training should be brief, hard, and infrequent.

Who he was
Arthur Jones founded Nautilus and designed its cam-based machines, aiming to load a muscle evenly through its full range. He was a blunt, combative advocate for training hard and briefly — the temperament, as much as the method, carried into HIT as it is known today.
What he argued
Jones's case was that intensity, not volume, drives adaptation: one hard set taken to failure does the work that many easy sets cannot. From that followed the rest — abbreviated sessions and reduced frequency, because harder training needs more recovery. It is the root of brief, hard, infrequent.
The lineage
The clearest line runs from Jones to Mike Mentzer, whose Heavy Duty pushed the single-set, high-intensity idea to its logical end. The method Failure Point tracks is the descendant of that argument.
Frequently asked
Did Arthur Jones invent HIT?
He popularised and codified it in the 1970s around his Nautilus machines. The underlying idea of hard, abbreviated, single-set training predated him, but he gave it a system and an audience.
How does this connect to Mike Mentzer?
Mentzer trained and worked in the Nautilus orbit and took Jones's principles further into his own Heavy Duty method.
Failure Point is a training logbook, not medical advice. Training to failure carries injury risk; consult a physician before starting any intense training program.
