RECOVERY PROTOCOL · §1.0
Recover what is fatigued. Keep growing what is ready.
Calyber eases the one muscle that is under-recovered and keeps the muscles that are still ready progressing, so recovery does not cost you a week of growth.
- Fatigued area
- Reduce stress
- Ready area
- Keep progressing
Net resultRecover without wasting the whole week
RECOVERY DECISION STACK
- SquatReduce sets, raise RIR
315 x 4, target missed
Readiness below threshold, second session
- Bench PressContinue progression
225 x 8, on target
Performance stable
- Lateral RaiseMonitor, no overreaction
30 x 12, setup varied
Low benchmark reliability
Example: one session, three different calls.
BLUNT DELOAD vs CALYBER
Most deloads are too blunt.
A fixed deload reduces stress for the whole body on a schedule. That helps when fatigue is global. It cuts productive training short when only one muscle group, one lift, or one session needed a temporary reduction.
vs
A response scaled to what is fatigued.
- QuadsRecover
- ChestBuild
- BackMonitor
- ShouldersHold
- Triggered by logged performance and fatigue signals.
- Only the affected muscle or session eases off.
- Recovered lifts keep progressing.
- Fatigue is read locally, per muscle group.
Fixed deloads are blunt because fatigue is local, not global. Autoregulation treats recovery as a ruleset, not a fixed date.
THE RULE
Recovery should follow a rule, not a mood.
Calyber does not ask you to guess whether you feel recovered. It uses logged performance, fatigue signals, workload, and recovery context to decide whether training should keep progressing, pull back locally, or enter a stronger deload state.
Each session runs the same checks, in order. One missed session is not a reset.
Check 1
Performance below the readiness threshold?
No
Continue progression
Yes
Monitor the next exposure
Check 2
Did the same readiness problem repeat next session?
No
Do not overreact
Yes
Suggest reactive deload
The rule
Reactive deload is suggested when two consecutive sessions both fall below the readiness threshold, not when you simply feel tired.
THE PROTOCOLS
Five graduated responses, not one blunt reset.
The response scales with how far fatigue has spread, and how long it has persisted.
Step 4RIR target 6
Reactive deload (mid-cycle)
A stronger reset after two sessions below the readiness threshold.

INSIDE THE APP
See exactly what changes before you apply it.
Calyber shows the scope, affected exercises, set changes, and RIR changes before the protocol is confirmed. Recovery is not hidden. You can see what is being adjusted before you accept it.
- 1Choose how far recovery applies
- 2Only the affected work changes
- 3See exactly what gets reduced
- 4Effort target rises to reduce fatigue
- 5Nothing changes until you confirm
Recovery changes are applied deliberately and require confirmation inside the app.
12345ONE WORKOUT, DIFFERENT OUTCOMES
More productive weeks. Less wasted fatigue.
When one muscle group is under-recovered, Calyber can reduce stress there while keeping productive training moving elsewhere.
That means recovery does not have to feel like losing a week. You can pull back where the signal is clear, keep training where performance is still stable, and stay inside the rhythm of the block.
Example flow. The same session produces a different decision per lift.
SquatRecovery suggested
Readiness low, two sessions running
Sets reduce, RIR target rises on the next quad session.
Bench PressProgression maintained
Performance on target, fatigue stable
The prescription holds its planned progression.
Lat PulldownUpdated upward
e1RM trend up, fatigue low
Load steps up on the next session.
A full deload should not be the only tool between keep pushing and block ruined.

Block review
What moved, what stalled, what changed.
Each step feeds the next. Recovery is part of the loop, not a pause in it.
If quads are cooked, chest training does not need to die with them. Recovery stays local, temporary, and tied to the data instead of forcing every muscle into one call.

Start a block that knows when to push and when to recover.
Train hard where you are ready. Recover where the data says it is time.
