Round Timer guide
How long is a boxing round? Round times for boxing, MMA and HIIT
A professional boxing round lasts 3 minutes, with 1 minute of rest between rounds, and title fights are scheduled for 12 rounds. Amateur bouts are usually three rounds of 3 minutes. Professional MMA rounds are 5 minutes with 1 minute of rest, and Muay Thai is commonly five rounds of 3 minutes with 2 minutes of rest. For training, the same rhythm works on the bag, the pads and in circuits.
Round times by sport
| Format | Rounds | Round | Rest |
|---|---|---|---|
| Professional boxing (title fight) | 12 | 3 min | 1 min |
| Professional boxing (shorter bouts) | 4 to 10 | 3 min | 1 min |
| Amateur boxing | 3 | 3 min | 1 min |
| Women's professional boxing | Up to 10 | 2 min | 1 min |
| MMA | 3 (5 for title fights) | 5 min | 1 min |
| Muay Thai | 5 | 3 min | 2 min |
Rules vary between governing bodies, age groups and countries. Youth and novice bouts often use shorter rounds, so check your own federation's rules before a competition.
Round times for training
You don't have to train at fight length. Matching your rounds to your goal makes sessions better:
- Bag work and shadow boxing: 3-minute rounds, 1 minute of rest, 6 to 12 rounds. This builds the pace you'll fight at.
- Technique on the pads: 2-minute rounds with 1 minute of rest keep the quality high.
- Fight preparation: some fighters train 3:30 or 4-minute rounds with 30 seconds of rest, so fight rounds feel easier.
- Beginners: start with three or four 2-minute rounds and build up over a few weeks.
Tabata, HIIT and EMOM explained
| Format | How it works | Total |
|---|---|---|
| Tabata | 8 rounds of 20 seconds all-out, 10 seconds rest | 4 minutes |
| HIIT 40/20 | 40 seconds of work, 20 seconds rest, often 10 rounds | 10 minutes |
| EMOM | Every minute on the minute: start a set at the top of each minute and rest for what's left | Usually 10 to 20 minutes |
Tabata is named after Izumi Tabata, whose 1996 study used the 20/10 pattern at very high intensity on an exercise bike. Done properly it is hard; four minutes is plenty.
Setting up Round Timer
Round Timer is a free gym timer in your browser, with big numbers you can read from across the room. It keeps the screen awake while it runs and works offline once loaded.
- Tap a preset: Boxing 12×3, Amateur 3×3, Boxing 10×2, MMA 3×5, Muay Thai 5×3, Tabata, HIIT 40/20 or EMOM 10.
- Or set your own: rounds (1 to 99), work and rest times, a get-ready countdown and a warning before the end of each round (the clapper).
- Press Start. The bell rings at the start and end of every round, rest ends with beeps, and the screen shows the round number and time left.
- Options: spoken round numbers, vibration on the bell on supported phones, and full screen.
- Keyboard: Space starts and pauses, S skips, R resets.
Your last settings are remembered, and finished sessions appear under Recent sessions.
Common mistakes
- Training every round at fight length from day one. Build up rounds and length over weeks.
- Skipping the warm-up. Use a few minutes of skipping or shadow boxing first.
- Sitting down between rounds. Stay on your feet, breathe slowly and shake out your arms.
- Ignoring the clapper. The last 10 seconds are where fitness is built.
- Calling everything Tabata. True Tabata is all-out effort. Moderate 20/10 work is just intervals, which is fine.
- No water to hand. Drink in the rest periods, especially in long sessions.
