How long to rest between sets
Rest longer for heavy strength work and shorter for endurance. As a rule of thumb: 2 to 5 minutes for strength, 1 to 2 minutes for muscle growth, and 30 to 60 seconds for muscular endurance. A rest timer keeps you honest.
Rest time by goal
| Goal | Typical reps | Rest between sets |
|---|---|---|
| Maximal strength | 1 to 5 | 2 to 5 minutes |
| Muscle growth (hypertrophy) | 6 to 12 | 1 to 2 minutes, longer for big compound lifts |
| Muscular endurance | 12+ | 30 to 60 seconds |
| Circuits / conditioning | Varies | As little as needed to keep moving |
These are common guidelines used by strength coaches, not hard rules. Big lifts like squats and deadlifts usually need more rest than isolation work like curls. If your reps drop off sharply on the next set, you probably rested too little.
Why use a rest timer?
Most people guess their rest and get it wrong: they scroll their phone for 4 minutes between sets of curls, or rush back to a heavy squat after 60 seconds. Timing your rest makes workouts shorter, more consistent and easier to compare week to week.
The rest timer in Gym Timer Pro
Gym Timer Pro's Lifting Pro mode is built for lifting sessions: a warm-up, your training block, and a cool-down in one flow. Between sets, tap a one-tap rest preset (30 s, 1, 1.5, 2, 3 or 4 minutes) and the timer counts down on a big ring you can read from the rack. Skip Rest if you are ready early.
- Open Lifting Pro from the home screen.
- Start your workout (or skip the warm-up and train right away).
- After each set, tap a rest preset that matches your goal from the table above.
- Finish the workout and save it to History and Apple Health.
Questions
How long should I rest between sets to build muscle?
A common guideline is 1 to 2 minutes for most hypertrophy work, and longer (2 to 3 minutes) for heavy compound lifts like squats, deadlifts and bench press.
How long should I rest between sets for strength?
For heavy sets of 1 to 5 reps, most coaches recommend 2 to 5 minutes so you can lift close to your best on the next set.
Is there a free rest timer app for the gym?
Gym Timer Pro is a free iPhone app with a one-tap rest timer between sets (30 seconds to 4 minutes), plus Tabata, EMOM and AMRAP timers. It has no ads and no subscription.
Does resting too little hurt progress?
Resting too little on heavy lifts usually lowers the weight or reps you can do on the next set. For endurance and circuit work, short rest is part of the goal.
