Workout timer
A free workout timer preset to a 30-minute session, with Repeat mode for rest periods between sets. The ring is big enough to read from the squat rack, and keyboard keys mean no sweaty thumb on a tiny phone button. Also searched as gym timer, exercise timer, rest timer for sets.
Rest between sets
| Goal | Reps per set | Rest | Timer to open |
|---|---|---|---|
| Strength (heavy) | 1–5 | 2–5 min | 3 minute timer |
| Hypertrophy (muscle size) | 6–12 | 60–90 s | 90 second timer |
| Endurance / circuits | 12–20+ | 30–60 s | 45 second timer |
| Power (jumps, throws) | 1–5 | 2–3 min | 2 minute timer |
These are typical ranges; rest a little longer for big compound lifts and a little less for isolation work.
Running rest periods with Repeat
- Click the digits and set your rest length, or press a digit key for whole minutes.
- Tick Repeat.
- Finish a set, press Space, rest until the alarm.
- Lift while the next countdown runs, then press Space to pause and reset on the next rest, or simply let it run as a pacing clock.
Timing the whole session
Leave this page at 30 minutes and start it when you begin the first working set. A glance at the ring shows whether you are dawdling between exercises. For longer sessions use the 45 minute timer or 1 hour timer. To measure how long a set or a run actually took, switch to the stopwatch and tap L for laps.
Other training formats
- Interval timer for work/rest schemes like 30/30 and 40/20.
- HIIT timer for high-intensity sessions with example workouts.
- Tabata timer for the four-minute 20/10 protocol.
- Plank timer for timed holds with a progression table.
