The Protocol

Maximum Mass.
Minimum Volume.

Built on the Heavy Duty methodology — the high-intensity training protocol behind the most complete physiques in bodybuilding history. GOHVY enforces every principle automatically.

One Set to Failure

Two progressive warm-ups, then one Heavy Duty set pushed to absolute mechanical failure in the 6–8 rep range. No junk volume. No second chances.

6–8 REP TARGET
CNS Rest Lock

One day on, one day off minimum. After a session logs, the app locks the next workout until your central nervous system has recovered. Override if you're ready early.

AUTO RECOVERY GATE
Auto Progression

Hit 8+ reps and the weight goes up next session. Hit 4–7 and you hold. Hit 3 or below and you deload 10%. The engine calculates it automatically.

CALCULATED PER EXERCISE
Interchangeable Splits

Three workouts — Shoulders/Chest, Back/Arms, Legs. Complete all three in any order within 7 days. Your schedule, your sequence.

3 WORKOUTS / 7-DAY CYCLE

Workout Tracks

GOHVY 3 Day
Standard Track

Select whichever workout fits your day. Completed workouts grey out. The week resets automatically once all three are checked off. Three sessions a week — recovery outside the gym does the rest.

GOHVY
Expert Track

The Lineage

What Is Heavy Duty Training?

Heavy Duty is the original high-intensity training (HIT) method: brief, infrequent workouts where a single working set is taken to absolute muscular failure, followed by real recovery. Where conventional programs chase volume, Heavy Duty chases intensity — one honest set outworks a dozen casual ones. GOHVY turns that philosophy into software: it schedules your three weekly sessions, enforces recovery between them, and calculates every weight increase for you. New to the method?
