Interval Timer – Timer for Interval Training and Workouts
The interval timer guides you through interval training work and rest phases with audio cues. Set work phase, rest phase, and number of rounds, and the timer handles the timing automatically.
The tool is perfect for HIIT workouts, Tabata (20s work / 10s rest × 8), CrossFit, cycling intervals, and any interval-based training. You can customize work and rest times and add longer recovery periods between rounds.
What is Tabata training and how does it work?
Tabata is a protocol developed by Dr. Izumi Tabata: 20 seconds maximum effort, 10 seconds rest, 8 rounds = 4 minutes. Research shows that 4-minute Tabata improves both aerobic and anaerobic fitness more effectively than 60 minutes of moderate endurance training. The interval timer handles all timing automatically.
