Adaptive hypertrophy training

SAMPLE READOUT

Training productively through a cut.

A lifter dieting in a calorie deficit. Recovery shrinks, so Calyber trims weekly volume toward the recoverable floor while load holds.

Sample inputs, real engine. The lifter is fictional; the prescriptions and estimates are the engine's real output. This is a modeled scenario, not a promised result.

The decision

The call this block turns on.

Fixed plan

Keep adding sets and weight as if recovery were unchanged.

Calyber

Trim weekly volume toward the recoverable range while load holds.

What it sees: Recovery shrinking in the deficit, with fatigue measurable on the lower body.

In a deficit, protect the work you can recover instead of chasing more.

Calyber recommendation

Week 2 update

Chest

Weekly volume: 6 to 6 sets

DecisionHold volume

Why this changed

The raw feedback pointed toward a volume change, but the engine's priority and recovery rules held the target steady for this muscle.

Recoverable range: MEV 6 to MRV 16 sets
New weekly target: 6 sets

Engine trace available

The block

Strength held while volume gave way.

Four days a week through a calorie deficit. As recovery shrank, Calyber trimmed weekly volume toward the recoverable floor while load held, then closed with a planned deload.

Week 2 · ChestVolume held6 → 6 sets (0/week)
The raw feedback pointed toward a volume change, but the engine's priority and recovery rules held the target steady for this muscle.
▸Engine trace
MEV 6MRV 16
Good stimulus (net=1.0) -> +1 set | Slow-recovery muscle held steady unless under-stimulated [priority=GROW, recovery=SLOW, muscle=Chest]
Why the volume held
Week 4 · QuadsVolume cut6 → 6 sets (-2/week)
High fatigue and a measured drop in performance triggered a volume cut, so recovery could catch up before the work resumed.
▸Engine trace
MEV 6MRV 16
Still sore AND workload too much -> -2 sets [priority=GROW, recovery=SLOW, muscle=Quads]
See the recovery protocol
Week 6 · All musclesDeload
The final week is a planned deload. Volume and load drop so accumulated fatigue clears before the next block.
▸Engine trace
Scheduled deload: target RIR 8, loads capped near 50 percent of peak estimated 1RM.
