A good judo warm-up takes about fifteen minutes and follows a simple logic: wake up the joints, raise your heart rate gradually, do some breakfalls, then drill a few technical entries without forcing. The goal is to reach randori warm and mobile, without wasting energy.
Too many classes still start with ten minutes of jogging around the mat and go straight into throws. That's the quickest way to strain a calf or jam a finger.
A 15-minute judo warm-up routine
This routine suits adults and teenagers. You can do it in a group or alone, on a mat.
Minutes 0 to 3: joint mobility
Standing, work from the feet up to the head: ankles and knees first, then hips and spine, then shoulders and wrists. Slow circles, about ten in each direction. Spend time on your fingers by opening and closing them fast, because they'll take a beating from the first judogi grips.
Minutes 3 to 7: gradual cardio and movement
Light jogging, side shuffles, running backwards, high knees. Then judo footwork in tsugi-ashi (sliding steps where the back foot catches up with the front one without passing it). Finish with ground movement: crawling on the forearms, shrimping (moving sideways by pushing with the hips), forward rolls.
Minutes 7 to 10: breakfalls
Backward falls, then side falls on both sides, then forward rolls. Ukemi belong in the warm-up, not in a separate drill. They warm up the back, neck and shoulders exactly the way randori will load them.
Minutes 10 to 15: judo-specific activation
In pairs, about twenty light uchi-komi (entry repetitions) on your favorite technique, right side then left. Then a minute of grip fighting where you simply try to get your grip while your partner does the same, with no throws. The basics of this work are in our article on kumikata (gripping).
By now you should be sweating lightly and breathing faster than at rest, without being out of breath.
Why to skip long static stretches before training
Holding a static stretch for thirty seconds before randori doesn't do much for a judoka. The muscle relaxes, and then you ask it to explode into a hip entry. Dynamic movements work better: leg swings, lunges with a trunk twist, walking hip openers.
Long stretches have their place after the session, when the body is warm and you're winding down. They're also part of good judo recovery.
Adapting the warm-up to the class
A technical class doesn't call for the same warm-up as a hard randori session. Before a groundwork (ne-waza) class, replace the standing movement with more floor work: shrimps, bridges and turnovers. Before a nage-komi session, where you throw for real, double the time spent on breakfalls.
With children, everything goes through games. The same goals are reached with chasing games, animal walks and small pushing contests. A routine that feels like school bores them, and they warm up badly.
For adults over 40, extend the mobility block and slow down the cardio build-up. Two extra minutes at the start cost far less than a week off. Our article on judo injuries lists the areas most at risk.
When you arrive late
It happens to everyone: work runs over, traffic is bad and class started ten minutes ago. Don't step on the mat and jump straight into the group's uchi-komi. Take three minutes at the edge of the mat for ankle, hip and finger mobility, do five breakfalls on each side, then join in. A good coach prefers a student who warms up late to one who gets injured on time.
If your club always goes straight into technique without a real warm-up, arrive early and do the routine alone. Nobody will hold it against you.
Common warm-up mistakes
- Arriving late and skipping the warm-up "because I ran to get here".
- Doing uchi-komi at full speed by minute five.
- Neglecting your weak side during breakfalls.
- Warming up, then sitting for ten minutes waiting for class to restart.
That last mistake is common at competitions. You warm up too early, the schedule runs late and you step on the mat cold.
Warming up on competition day
Your tournament warm-up should be the same routine you use in training. Don't try a new exercise that day. Start around thirty minutes before your estimated match time and keep a hoodie on until you're called.
Bring a clubmate for uchi-komi, or failing that a resistance band to drill your entries alone. Our judo competition bag checklist includes this kit. Between matches that are far apart, run a short five-minute version: footwork, a few breakfalls and ten entries. If it's your first tournament, also read our tips on preparing for your first judo competition.
Write your routine on a card and repeat it exactly for a month. A warm-up you know by heart calms you as much as it prepares you, and that is exactly what you need in a noisy competition hall.
