BJJ roll review: what it is and what a black belt looks for

What a roll review is

A roll review is a coach watching footage of your sparring and explaining what happened, why it happened and what to work on next. It is similar to an instructor pulling you aside after class, except the coach has the whole roll on video and can pause it at any moment.

Many grapplers film their rolls, but the footage rarely gets more than a quick look.

Why your own roll is hard to judge

During a roll you are tired, your heart rate is up, and your view is from inside the exchange, often from underneath. Afterward, you remember how it felt: where you got stuck and when you got tapped.

The moment that decided the outcome often came earlier. It may have been a grip you gave up, a frame that collapsed or a sweep you never noticed. An experienced coach can spot these details on video.

What a black belt looks for

A good review covers six areas.

Who controls the grips, when you lose them, and whether your posture holds under pressure.

Where you spend the roll, how you move from one position to the next, and where you give up ground.

The moments where you had a choice, the option you took, and a better option if there was one.

Sweeps, passes, back takes and submissions that were available and went unused.

Patterns that keep putting you in bad spots, such as flat hips, late frames or exposed arms.

Where you waste energy without gaining position, and where you should have pushed the pace.

How a review differs for a training roll and a match

A reviewer judges a training roll against what you set out to do in it. If you started in a bad position or gave up a pass on purpose to work your escapes, the review looks at the escapes rather than at how you got there. A sweep that landed easily on a partner who was going light shows you know the mechanics, but it has not yet worked against full resistance.

In a match, the ruleset decides which choices were sound, and IBJJF, ADCC and submission-only events reward different things. Under points rules, the reviewer checks whether each pass or sweep was held long enough to score. Under IBJJF rules, a sweep or submission attempt that came close can earn an advantage, which can decide a match tied on points. Under submission-only rules, holding a position earns no points, so the reviewer looks mainly at whether you used it to set up a finish. A match also shows which techniques you attempt and which you complete against an opponent who is trying to win and does not know your game.

What to tell a reviewer before they watch

Send a few lines of context with the footage. Start with your belt, how long you have trained and how often you train now. The same habit calls for different advice at white belt than at brown belt.

If you were working on something specific, name it. Describe your partner: their belt, their size compared with yours, and how hard they were rolling. Video shows size only roughly, rarely shows rank in no-gi, and cannot show whether a partner was holding back. For a match, name the organization and the ruleset.

End with the one or two questions you most want answered, such as why your half guard keeps getting flattened or why you lose the back soon after taking it. The reviewer can then spend the most time on the moments that answer them.

Ways to get your roll reviewed

There are four common ways to get feedback on your footage.

  1. Your own instructorKnows your game and can follow up on the mats. Sitting down with your footage is hard to fit around running classes.
  2. Posting it onlineThreads on r/bjj and grappling forums bring free comments, sometimes within hours. The quality depends on who answers, and most replies cover one or two moments.
  3. An AI appSeveral apps review uploaded footage and return feedback at any hour. Our comparison of AI and coach reviews shows where each is stronger.
  4. A black belt outside your gymYou pay a coach to go through the whole roll in detail, working only from the footage. This is how Grappling Breakdown works.

How to get a breakdown from us

Upload your footage from your phone, or paste a YouTube link. You can send training rolls and competition matches, gi or no-gi. A verified black belt reviews the roll and sends back a breakdown, usually within 48 hours. No part of the breakdown is done by AI.

What comes back

  • TimestampsKey positions, decisions and openings, marked on your footage.
  • VoiceoverThe coach talking you through the roll over your own video.
  • Written reportWhat went well, what to fix, and why.
  • HomeworkDrills to work on in your next training sessions.

You can watch other members’ breakdowns in the public library and read each coach’s profile on the coach roster before you send your own.
