HIIT & Interval Timer Guide

Quick answer

HIIT interval timers alternate work and rest phases with clear audio cues. Tabata is typically 20 seconds on / 10 seconds off for 8 rounds; EMOM starts a new move every minute. Use a dedicated interval timer so you are not staring at a phone clock mid-burpee.

Build a circuit

List phases in order: warm-up, work, rest, repeat count, cooldown. Confirm the alarm is loud enough over music. Place the display where you can glance without breaking form.

Tabata vs EMOM vs custom

  • Tabata — short, brutal, fixed 20/10
  • EMOM — skill or strength practice every minute
  • Custom intervals — sports-specific or rehab protocols

Run it in the browser

Chrono’s interval mode on iautre.com lets you stack phases without a gym subscription app. Pair with the Tabata or HIIT landing pages for presets, then save your preferred theme for the gym TV.

FAQ

Can I use an online timer at the gym?+

Yes on a phone browser or tablet. Lock orientation, raise volume, and disable auto-lock. A PWA install helps it feel like a native app.
