Which timer should I use?

Workout timer

Best for: Whole training blocks

Use for circuits, strength rests, supersets, warmups, and cooldowns.

Interval timer

Best for: Simple repeated work/rest

Use when the workout is just one repeated interval pattern.

Stretch timer

Best for: Gentle holds

Use when the session is mobility-focused rather than conditioning-focused.

Safety note

Use rest durations that preserve form and follow your coach, clinician, or program when applicable.

Frequently asked questions

Can I use this as a gym rest timer?

Yes. Start the timer after a set and use the recovery cue as your rest window before the next set.

Is this workout timer only for circuits?

No. It also works for warmups, cooldowns, supersets, conditioning finishers, and simple rest timing.

Will my workout history sync across devices?

Not yet. Completed sessions are stored locally in the current browser, with paid cloud sync planned as an upgrade path.

How long should I rest between workout sets?

Light circuits may use 15-30 seconds, hypertrophy sets often use 60-120 seconds, and heavy strength sets may need 2-5 minutes. Match the rest to your program and form quality.
