Boxing Timer: Free 3-Minute Round Timer
Run boxing rounds the way they're scheduled, 3 minutes of work and 1 minute of rest, for as many rounds as you set.
TL;DR
A boxing timer runs fixed rounds of work with a rest between them, the way boxing itself is scheduled: 3-minute rounds, 1 minute of rest, 12 rounds by default here, all fully adjustable. It shows a big clock, a round counter, beeps for the last 3 seconds of every round and rest, and a link that saves your exact setup.

Your screen stays awake while the timer runs, in browsers that support it.
Log Your Training After Rounds
PR Streak logs your training and starts your rest timer automatically between sets, with a countdown on your Lock Screen and in the Dynamic Island, so your next round always starts on time.
How Long Is a Boxing Round?
A professional boxing round runs up to 3 minutes, with 1 minute of rest before the next one starts. Championship fights are scheduled for 12 rounds, which is why this timer defaults to 3-minute rounds, 1-minute rest and 12 rounds, all fully adjustable for a shorter bout, a training session or a home workout.
How to Use This Boxing Timer
Set your round length, rest length and number of rounds, then hit start. A 10-second get-ready countdown gives you time to get your gloves on and step to the bag before the first bell.
A big clock counts down each round and rest period, with a round counter showing where you are out of the total. Beeps mark the last 3 seconds of every round and rest, plus the switch between them, standing in for the bell.
Pause, resume, reset or skip a round in one tap, run it full screen for ringside visibility, and copy the link to save your exact round and rest lengths.
Boxing Timer Setups for Training
Shorter rounds with the same 1-minute rest can turn this into a fast-paced sparring or mitt-work session, while stretching the round length toward a full 3 minutes builds the conditioning a real bout demands. Cutting the round count down makes a quick finisher; running the full 12 makes a fight-length session.
For pure conditioning work shorter than a full round, lifters sometimes switch to Tabata-style timing, 20 seconds of work and 10 seconds of rest, on the Tabata timer, or to a fully custom ratio on the interval timer. Pair your rounds with strength work from the exercise library on your off days.
Rest Between Boxing Rounds
A boxing round's 1-minute rest is fixed by the sport's rules, not chosen for muscle or strength recovery. Strength training research points to different numbers entirely: one study found 3 minutes of rest between heavy sets built more strength and muscle than 1 minute in the same lifters, over 8 weeks.
If you're pairing boxing rounds with a lifting session, a separate rest timer with quick picks up to 5 minutes covers that longer, strength-focused rest better than the fixed 1-minute round rest here.
Boxing Timer Safety Tips
- Warm up and shadowbox before your first full-intensity round.
- Keep your hands up and your form sharp late in a round as fatigue sets in.
- Use the rest fully. Skipping ahead into the next round early defeats the purpose of scheduled rest.
Used by lifters following PPL, 5x5, upper/lower, and more.
Frequently Asked Questions
How long is a boxing round?
A professional boxing round runs up to 3 minutes, with 1 minute of rest before the next round starts. This timer defaults to those exact lengths, and both are adjustable for shorter training rounds.
How many rounds are in a boxing match?
Championship fights are scheduled for 12 rounds, which is why this timer defaults to 12 rounds too. You can set any number instead, for a shorter workout, a sparring session or a quick round-based finisher at the end of a lifting day.
Can I change the round and rest length?
Yes. Round length, rest length and number of rounds are all adjustable, so you can run 2-minute rounds for training, 3-minute rounds for fight-length conditioning, or anything in between. Save your exact setup with the page's link once you find the combination that fits your session.
What's the rest between boxing rounds for?
The 1-minute rest between rounds is set by the sport's rules, not chosen for strength or muscle recovery. Strength training research favors a different, often longer, rest window for heavy lifting; see the rest timer for that.
Can I use this as a general round timer?
Yes. Set any round length, rest length and round count, then run it for sparring, mitt work, circuits, kettlebell complexes or any other rounds-based training, not only boxing. The get-ready countdown, big clock and beeps work the same no matter what you're timing.
Does this timer work for conditioning intervals shorter than a full round?
Yes, though for very short, high-intensity intervals like 20 seconds of work and 10 seconds of rest, the dedicated Tabata timer or the fully custom interval timer may fit better than a full boxing round.
