Adaptive hypertrophy training

SAMPLE READOUT

Restarting after time off.

A detrained lifter returning after a layoff. Calyber ramps volume up from a deliberately low base instead of throwing them back into old numbers.

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.

Fixed plan

Jump straight back to your old numbers.

Calyber

Ramp volume up from a deliberately low base as the early sessions prove easy.

What it sees: Sessions clearing comfortably, so there is room to rebuild.

Rebuild from where you are now, not where you left off.

Calyber recommendation

Week 2 update

Chest

Weekly volume: 6 to 7 sets

DecisionRaise volume

Why this changed

Chest recovered well and the sets were productive, so the engine added volume for the next week, bounded by the maximum recoverable volume.

Recoverable range: MEV 6 to MRV 16 sets
New weekly target: 7 sets

Engine trace available

The block

Rebuilt from where the body is now.

Three days a week after a layoff. Calyber ramped volume up from a deliberately low base as the early sessions came in easy, then closed with a planned deload.

What the engine changed, and why.

3 engine moments shaped this block. Open any trace to read the engine's own reasoning, verbatim.

Week 2 · ChestVolume raised6 → 7 sets (+1/week)
Chest recovered well and the sets were productive, so the engine added volume for the next week, bounded by the maximum recoverable volume.
▸Engine trace
MEV 6MRV 16
Recovered well + insufficient workload + low pump -> +1 set [priority=GROW, recovery=SLOW, muscle=Chest]
How the engine decides volume
Week 3 · QuadsVolume held9 → 9 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 8MRV 20
Neutral (net=0.5) -> hold steady | Emphasize priority: fresh + good stimulus -> +1 set | Slow-recovery muscle held steady unless under-stimulated [priority=EMPHASIZE, recovery=SLOW, muscle=Quads]
Why the volume held
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.
