The first decision
Start with two sessions, then earn the third.
Two weekly sessions create two chances to practice the same movement patterns without asking a returning trainee to reorganize every day around training. If that rhythm holds, a third session can distribute the work rather than simply adding more fatigue.
The first useful test is not whether the schedule looks ambitious. It is whether the same person can arrive next week with enough time and recovery to repeat the plan with clear positions and controlled effort.

The structure
Use frequency to distribute practice, not to collect sessions.
A full-body session can cover the major patterns with fewer weekly appointments. A three-day plan can reduce the amount asked of each session and make space for a little more practice. Neither schedule is automatically the advanced choice.
Keep the exercises recognizable while you learn what the schedule can hold. A changing menu makes it harder to know whether the training load or the calendar caused the drift.

The adjustment
Change one lever when the week stops fitting.
When recovery or time becomes the constraint, keep the training job and shorten the session, reduce a set, or return to two weekly sessions before replacing every movement. Small adjustments preserve a useful comparison.
If symptoms, medication, a diagnosed condition, or a clinical return changes the question, move the decision to a qualified professional rather than treating a generic frequency rule as a prescription.
