Nobody moves Do-Heun Chang. His program develops the immovable strength and mass of a fighter who simply cannot be knocked down.
Every phase, every session, every exercise — expand a day to see the full prescription.
Building the base — moderate loads, full technique focus (target RIR 3).
Heavier loads and denser conditioning. Target RIR 2.
Full Body & Functional, Lower Strength & Power, Upper & Conditioning, and Agility & Endurance.
Deceptively strong and quietly durable — muscle built for real work, not show.
Genuine full-body strength, functional lower-body power, and honest conditioning capacity.
Compound lifts progress by load, plyometric and sprint work progress by density. Phase two raises volume and shortens rest.
Do-Heun's build is real, functional muscle — deadlifts and presses for raw power, sprints and ladder work for the athleticism his frame doesn't advertise. Four honest sessions, no filler.
