Twelve three-minute rounds with one minute between — the professional championship distance. Shadow, bag, pads, and sparring to the bell.
Three five-minute rounds with one minute between — standard non-title MMA bout length for sparring or drilling.
Five three-minute rounds with two minutes between — the traditional Muay Thai clock. Pads, bag, clinch, or sparring.
Six five-minute rolling rounds with one minute between to reset and change partners — the way open-mat rolling runs.
A boxing timer runs a fixed number of rounds with a rest break between them, sounding a bell at the start and end of each one. It is the clock every fight gym lives by: nobody watches the time, everybody works until the bell, rests until the next, and always knows which round they are in. Shadow boxing, heavy bag, pads, or sparring — the round is the unit, and the timer keeps the count.
The defining feature is that count. Where a plain interval timer just alternates work and rest, a boxing timer numbers the rounds, so round three of twelve is a different place than round one. That lets you pace a session like a bout — measured early, emptying the tank late — instead of running it as an undifferentiated blur.
Each sport has its own clock, and training on the real one means your conditioning matches what you face under pressure. Boxing is fought in three-minute rounds with one minute of rest — three rounds for an amateur bout, up to twelve for a professional championship. MMA uses five-minute rounds, also one minute apart: three rounds for a standard bout, five for a title fight.
Muay Thai keeps the three-minute round but takes a longer recovery — two minutes between rounds, traditionally over five rounds. Grappling runs differently again: a Brazilian jiu-jitsu match is one long timed round, typically five to ten minutes by belt level, so a BJJ timer is usually a string of match-length rounds with a short reset between for rolling at open mat.
The rest between rounds is not dead time — it is what makes the next round honest. Recover like you are in the corner: hands down, deep breaths, sip water, reset. Resist the urge to keep moving through it, because the break exists so you can attack the round that follows instead of surviving it.
That is why the rest length matters as much as the round length. Boxing and MMA give you a minute; Muay Thai gives two because its rounds are denser with clinch work. Match the recovery to the demand of the round and the whole session holds together from first bell to last.
The presets below load the real competition clock for each sport — twelve three-minute boxing rounds, a three-round MMA bout, traditional five-round Muay Thai, and BJJ rolling rounds — each one tap from the opening bell. Start one as-is for a full session, or use it as a base.
Every preset opens in the editor, where you can set the round length, the rest, and the number of rounds to match your gym. For the underlying format and how the round count works across any sport, the generic round timer covers the structure; the presets here apply it to the bouts people actually train for.
