How we check every plan

Your plan is generated by AI — but the AI doesn't get the final say. This page explains, in plain language, the safety check every plan passes before it reaches you, and why that means you can trust what you see.

The AI never writes your plan as the final truth

An AI never decides your plan on its own. Every plan — and every change we suggest later — has to pass an automatic safety check before it becomes active. That check is a fixed set of rules written by us, not by the AI. It's the same check for everyone, every time. If a plan doesn't pass, you never train on it.

Three layers, in order

Every plan goes through three stages, in this order. If a stage finds a serious problem, the plan is sent back to be fixed or regenerated — it is not activated.

1. Structure check. First we confirm the plan is even well-formed — the right shape, with all the required parts present. A plan that doesn't fit the expected structure can't move on.
2. Safety rules. Next we run our safety rules. These respect your injuries and the equipment you have, stop a plan that includes movements that aren't safe for your reported injuries, and limit how quickly load and volume can increase. These rules can block a plan outright.
3. Programming rules. Finally we check that the plan is sensible training: a proper warm-up and structure, realistic workouts for your level, and a reasonable balance of movement types. Some of these can block a plan; others raise a flag for review.

Your injuries and equipment are built in

When you tell us about an injury, that isn't just a note — it's enforced. A movement that isn't appropriate for an injury you reported won't pass the safety check, and where it makes sense we reduce load instead of removing movements entirely. The same goes for equipment: we don't build a plan around gear you don't have.

What happens if you report pain

If you report pain at level 7 or higher, or a warning symptom — sharp pain, chest pain, dizziness, or numbness — the app stops suggesting that you push harder. We'll prompt you to stop the current exercise and check in with a physician or physiotherapist before returning to full training, and we hold back any progression in your next cycle until things settle.

This is a safety prompt, not a diagnosis. Smartensity does not provide medical advice — see our AI disclosure page.

A second review on top

On top of the automatic safety check, a separate AI reviewer looks over the plan and points to the specific rule behind any concern it raises. This reviewer is an extra layer — it never replaces the automatic safety check, and it can never let through a plan that the safety check would block.

Our safety rules are based on a maintained internal rulebook, and our thresholds are conservative by design. Where the evidence for a specific number is still being reviewed, we err on the side of caution.

It's still your decision

These checks make your plan safer, but they don't make it risk-free. Training has inherent risk, and only you (with a professional, if you have any doubts) can judge what's right for your body on a given day. If something feels wrong, stop. When in doubt, get a plan reviewed by a qualified coach or physician.
