BJJ Timer

This BJJ timer, also called a Jiu-Jitsu timer, is built for Brazilian Jiu-Jitsu training sessions on the mats. Set a round duration, a rest period and a number of rounds, then let the timer handle the clock while you focus on rolling, sparring and technique.

The same setup works for open mat, for structured drills and for positional rounds with a training partner. Audio and visual signals mark the start of each round and each rest period, so everyone on the mat starts and stops together — no one has to watch a wall clock or reset a phone between rounds.

A BJJ round timer runs a simple, repeating structure:

Round → Rest → Round → Rest, until the last round is finished.

Choose the round length that matches your session — shorter rounds for high-intensity sparring rounds, longer rounds for live rolling — and set the rest time you need between them. Five minutes is the most common round length for rolling, with one minute of rest to switch training partners.

Because every round is the same length, partners rotate at the same moment and the whole room stays on the same clock.

A full Brazilian Jiu-Jitsu training session usually moves through several blocks, and the same timer covers all of them:

Technique → Drilling → Positional sparring → Live rolling

Use short work intervals for technique drills and repetitions, medium rounds for positional drills from a specific position, and longer rounds for live rolling. Finish with grappling conditioning intervals if you want to add a fitness block at the end of the session. Adjust the round and rest values between blocks and press start again.
