The Perpetual Trainer · Conditioning
BUILD YOUR ENGINE.
Choose what you have, choose the effort, and press Start. No heart-rate formula is required. Use the talk test and your own control to keep the session honest.
1 · What are you using?
CHOOSE THE MODE
The training job matters more than the machine.
2 · What is the job?
CHOOSE THE EFFORT
These are training choices, not medical or readiness scores.
Easy Base Keep the pace comfortable enough to speak freely. Finish feeling like you could have continued.
3 · How much time?
CHOOSE THE DURATION
Time changes the dose. It does not make the session a failure.
4 · Optional scenery
CHOOSE YOUR SCENE
Scenic motion stays separate from coaching. Mountain Ruck Trail includes its original gravel-step ambience.
Moving scenery is optional. Mountain Ruck Trail keeps the original subtle gravel-footstep sound at a low level under coaching; every other scene remains silent. Scene Off stops both motion and trail ambience.
Timer behavior Keep this page visible while your session is running. Switching tabs or locking your screen pauses the timer. Return and tap Resume to continue.
Safety boundary Stop for new chest discomfort, fainting or near-fainting, unusual shortness of breath, a sudden severe or rapidly worsening symptom, or another problem that needs professional guidance. This player does not diagnose the cause.
