Calyber turns them into a calibrated training plan.
Which phase to run. How much volume to train. You set the objective, and the engine sets volume, progression, and recovery to match it. Every recommendation traces back to your own logged sets.
We can't tell you your goal. That part is yours.
You set the direction. Calyber handles the calibration. Here is the split, end to end.
Most lifters pick a phase on feeling, then wonder why months pass without the result they wanted. Calyber does not choose for you. It makes the consequence of each choice explicit, then adapts the plan to the goal you set.

Too few hard sets and you leave growth unclaimed. Too many and the session costs more recovery than it returns. The productive range moves with your experience, sleep, stress, and the week's accumulated fatigue.
How Calyber sets volume
You do not count sets or chase volume targets.
One week, one decision
Reduce pressing volume by 2 sets next week.

Calyber adjusts from what it can measure. It does not pretend to see the rest of your life. Knowing the line is what keeps the prescription honest.
It infers recovery only from how your performance and fatigue signals move. It does not choose your goal, and does not promise one perfect volume number.
Training volume is a major driver of hypertrophy, but the right amount is individual and changes with the muscle, your experience, the phase, and your recovery. Calyber starts conservatively and adjusts from your logged response rather than assuming a fixed target.

It depends on your goal, body composition, timeline, and the tradeoffs you accept. Calyber does not choose for you. Once you pick the phase, it adjusts volume, progression, and recovery to match it.
There is no universal number. Calyber starts each muscle near its minimum effective volume, then adds, holds, or reduces sets based on your logged performance and fatigue.
It is the lowest weekly set count likely to produce progress for a muscle under your current conditions. Calyber treats it as a conservative starting point, not a fixed constant, then adjusts from your logged response.
No. You set the objective. Calyber calibrates the execution: starting volume, progression, recovery, and deload timing.
It reads your performance trend, set completion, and fatigue signals. It adds a set when adaptation holds, holds volume when the response is unclear, reduces when fatigue outpaces adaptation, and deloads when accumulation persists.
A cut narrows the recovery window, so Calyber tends to hold volume more conservatively and control fatigue tighter. It does not force volume to a fixed low number; it adjusts from how your logged performance holds up.
By the end of your first block, Calyber has enough logged data to calibrate volume and progression to you.
