Muay Thai Timer

Muay Thai Timer is a free online round timer designed for Muay Thai training, Thai boxing workouts and fight preparation. Set your round length, rest time and number of rounds to structure bag work, pad work, shadow boxing, conditioning and sparring sessions. The timer uses clear audio signals so you can focus on your technique instead of watching the clock. It runs a preparation countdown before the first round, switches between rounds and rest periods automatically, and works on a phone, a tablet or a laptop with nothing to install.

Train with a Muay Thai timer the way you would train with a gym bell. You set the rounds, the rest periods and the preparation time, press start, and the timer runs the whole session on its own. It opens with a short countdown so you have time to get your gloves on and reach the bag, then starts the first round.

When a round ends, the timer signals it, switches straight into the rest period and opens the next round automatically. There is nothing to reset between rounds and nothing to tap with your hands wrapped. Every transition is marked by an audio alert, which is what makes the session hands-free: leave your phone or laptop on the bench and let the sound tell you when to work and when to breathe.

Because the round duration, the rest period and the round counter stay identical from one session to the next, a Thai boxing workout becomes repeatable. Shorten the rest as your conditioning improves, add rounds as you progress, or lengthen the round when you are preparing for a fight format.

Heavy Bag Training

The standard heavy bag format is 3 minutes of work and 1 minute of rest. Structured rounds give you room to work through full combinations instead of hitting the bag until you run out of breath: punches into kicks, teeps and switch kicks, knees in the clinch position, elbows on the inside, and pure conditioning rounds where the target is output rather than technique.

Pad Work

Pad rounds follow the same 3-minute structure, but the timer works for two people. The trainer holds and calls combinations while the fighter works, and neither of them has to keep an eye on a clock. When the bell sounds, the round ends for both, the rest period starts and the next round opens on schedule — which keeps a long pad session on time even in a busy gym.

Muay Thai Sparring

For sparring, set the round duration, the rest period and the number of rounds before you glove up, then leave the timer running in fullscreen. Both partners hear the same signal, so rounds start and stop together. Keeping the same structure every session also makes sparring easier to control: the intensity changes, the format does not.

Shadow Boxing

Shadow boxing rounds are where footwork, angles and combinations get rehearsed without impact. Two- or three-minute rounds with a short rest work well as a warm-up before bag work, or as a full session on their own when you want volume and movement rather than power.

A Muay Thai workout can use the same basic round structure as boxing, but training sessions often include techniques that are specific to Thai boxing, including kicks, knees, elbows, clinch work and pad drills.

The round engine behind both timers is the same: a round, a rest period, repeated for a number of rounds. What changes is the way the page is set up — the presets, the default round length and the round counter are written for the format you actually train in, so you load a session in one tap instead of rebuilding it every time. If you train in both, use the Boxing Timer for boxing rounds and this page for Muay Thai.
