Fitness tips

🏋️

For Tabata workouts (20s work / 10s rest × 8 rounds), use the lap button after each work or rest phase to track interval consistency.

💡

The fastest/slowest lap highlighting shows whether your intensity is dropping over rounds — useful for tracking endurance improvement over weeks.

⌨️

Use the keyboard shortcut Space to start/stop without taking your hand off the mat. Great for floor exercises where you can't easily touch your phone.

📊

Copy your laps after a workout to log to a fitness journal or spreadsheet. The tab-separated format pastes cleanly into Google Sheets or Excel.
