Frequently Asked Questions — Interval Timer
What is a Tabata timer and how does the interval timer work?
A Tabata timer alternates between 20 seconds of intense work and 10 seconds of rest, repeated for 8 rounds (totaling 4 minutes). Our interval timer offers 6 built-in presets: Tabata (20/10), 30×30, 45×15, 60×30, 90×30, and 3:1 (3 min work / 1 min rest). You can also customize work time, rest time, and number of rounds. Audio beeps signal transitions.
What is the gym timer used for?
The interval timer is a versatile gym timer for HIIT workouts, CrossFit training, boxing rounds, circuit training, and any workout that alternates between work and rest periods. With presets ranging from 20-second Tabata rounds to 3-minute heavy lifting sets, it accommodates all training styles. The Skip button lets you advance to the next phase if you finish early. Pair your workout with our Stopwatch for rest period tracking or use the Sound Mixer for motivating background ambiance.
