A plan starts with an intention.
A workout might prescribe three sets, a timed hold or a short sequence of intervals. Those instructions describe the work you intend to do. By the end of the session, you may have changed the load, shortened a hold, skipped a movement or stopped an interval early. A useful training history needs room for that difference.
This becomes especially important when a training app uses AI. A polished summary can sound certain even when its source is only a timer or a target. Hyperion keeps the plan, measured time and recorded outcome distinct so the history and coaching have a clearer account of what happened.
What the clock actually knows.
When a guided timer reaches the end of a hold, it knows how much time elapsed. It has not counted your repetitions, checked your range of motion or assessed the quality of a pose. Hyperion records measured time without turning it into a claim that those other things were verified. Recovery transitions also remain separate from performed work.
The same principle applies to rounds and intervals. A few recorded repetitions can be meaningful partial work without becoming a completed round. If a session is repeated as a template, its instructions can be reused while the previous outcomes are cleared. Yesterday's completed exercise should never arrive pre-completed in today's workout.
Stay in control of progression.
Guided activity includes automatic and manual progression. Manual progression keeps the clock running while you decide when to log or move on; pausing is a separate action. Returning to automatic progression after a target has passed requires confirmation, rather than silently advancing through steps you have not acknowledged.
This also matters in mixed sessions. A warmup, a timed activity and a lifting block have different needs. Block boundaries pause, and lifting continues through the set logger instead of starting automatically. The latest Android recovery work also improves the return from guided activity to manual lifting while retaining the session's sets and recorded time.
An unknown measurement can stay unknown.
Outdoor GPS is optional. Signal gaps, unavailable services or rejected position jumps can leave pace or distance incomplete. In those cases, the app can retain time or use measurements you enter. A plausible number would look tidier, but it would make the workout record harder to trust. Indoor activity does not require location permission.
When reviewing a session, ask what each number represents: a prescription, elapsed time, a device measurement or something you entered. That habit makes comparisons more useful and helps explain why two sessions with the same planned workout can produce different records. Hyperion's guided activity and private routes are alpha features; additional Running Speed, HIIT and Yoga/Mobility programmes remain in validation before being enabled.
