Overview
Ninety-second rests build strength; shorter rests suit endurance. Match rest timers to your program.
Start the rest as soon as you rack the bar. Pick the weight back up when it rings, instead of waiting for a song to end.
How to use it
- Open HIIT Timer.
- Set work, rest, and rounds before you start, and put the screen where you can see it from the floor.
- Keep Tabata Timer or Online Stopwatch for a second phase.
Good to know
This is a training clock, not medical advice. Stop if something hurts, and keep the screen awake so the interval change is not delayed.
