How to use the online timer
Workout timing lives and dies on the gap between work and rest, and that ratio is what actually defines a training style far more than the exercises themselves — a HIIT session and a steady-state run both burn energy, but the short, hard bursts against brief recovery in one are doing something structurally different to the sustained, even effort of the other. Getting that rhythm right, and repeating it accurately round after round, is harder to do by watching a clock on the wall than it sounds.
This collection covers the common structures — Tabata's brutal twenty-ten split, EMOM's self-pacing minute-by-minute format, steady endurance efforts for running and cycling, and the longer rest periods proper strength training actually needs between heavy sets. Each one is built around what that particular style of training is trying to achieve, rather than a single generic countdown applied to everything.
Set the timer, run through your warm-up, and let the buzzer manage the rhythm so your attention stays on form and effort rather than watching the seconds tick over.
