AI workout plan generator: what's actually under the hood

Red flag #1 — same plan for every user

If a generator outputs the same week regardless of equipment, history or recovery, it isn't generating anything. It's selecting from a small library.

Red flag #2 — no progression model

A real generator must model how the next week's loads change based on what you did this week. Otherwise it's a one-shot template.

What current AJYX source supports

AJYX currently exposes a workout builder, progression engine, body-recovery surface, form-coach surface and coach chat. Recorded training history, equipment, completed sets/reps/load and reported effort can provide context; recovery information can add context when it is available.

A generated recommendation is an interpretation of recorded inputs, not a direct measurement of readiness. Missing or inconsistent data should reduce confidence rather than be silently invented. See /methodology for AJYX's current data and inference boundaries.

When AI is not enough

Competitive preparation, pain, injury, rehabilitation and medical decisions require appropriately qualified human judgement. AJYX is a general fitness product and should not be presented as diagnosing injury or replacing clinical assessment.

Evidence and limits

Resistance-training progression should change training stress over time rather than simply repeat a static template. Source: American College of Sports Medicine, Progression Models in Resistance Training for Healthy Adults — https://pubmed.ncbi.nlm.nih.gov/19204579/
