Adaptive hypertrophy training

SAMPLE READOUT

A first block, adjusted week by week.

A newer lifter runs their first structured hypertrophy block. Calyber starts conservatively, tracks performance, adds volume only where recovery allows, and finishes with a planned deload.

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

Start heavy and chase big jumps from day one.

Calyber

Start conservative and add volume only where the logged sets show recovery.

What it sees: Early sessions clearing comfortably, so there is room to add work.

A first block builds the habit and the data, not a one-week peak.

Calyber recommendation

Week 2 update

Quads

Weekly volume: 8 to 8 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 8 to MRV 20 sets
New weekly target: 8 sets

The block

A first block, built without guesswork.

This lifter trained three days a week through their first structured block. Calyber started conservatively and added volume only where the logged sets showed recovery, then closed with a planned deload.

Week 2 · QuadsVolume held8 → 8 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 2 · BicepsVolume raised6 → 7 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.
▸Engine trace
MEV 6MRV 16
Good stimulus (net=1.0) -> +1 set [priority=GROW, recovery=FAST, muscle=Biceps]
How the engine decides volume
Week 5 · 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.
