Adaptive hypertrophy training

SAMPLE READOUT

When life gets in the way.

A busy lifter who logs fewer sets than prescribed on some weeks. Calyber compares like for like and re-prescribes from what was actually done.

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

Treat a missed week as lost progress and pile on to catch up.

Calyber

Compare like for like and re-prescribe from what was actually completed.

What it sees: Fewer sets logged on the busy weeks, with performance per set holding.

A lighter week is data, not a failure to punish.

Weekly volume: 6 to 6 sets

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.

The block

Uneven training time, handled without punishment.

This lifter trained three days per week, but some weeks had fewer completed sets. Calyber used the work actually logged to update the next prescription instead of forcing catch-up volume.

What the engine changed, and why.

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

  1. Week 2 · ChestVolume held66 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
  2. Week 2 · BicepsVolume raised67 sets (+1/week)

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

    MEV 6MRV 16

    Good stimulus (net=1.0) -> +1 set [priority=GROW, recovery=FAST, muscle=Biceps]

    How the engine decides volume
  3. 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.

    See the recovery protocol

Training time uneven? Log what you can and let Calyber re-prescribe from your real sessions, missed sets and all.
