Mouthguards: stop wearing the boil-and-bite, please
Boil-and-bite mouthguards do almost nothing in actual rolling. They flop, they cut your gums, and they can come loose mid-scramble. A custom guard from your dentist is $80-150 and lasts years. If $150 is too much: SISU 2.4mm at $25 is genuinely close to custom and is the only OTC I'd recommend. I've had two teammates lose teeth in the last year. Both wore boil-and-bite.
Strength differential: how to roll productively with men 30kg heavier
Most days I'm the smallest person on the mat. The bigger men either go too easy (and I learn nothing) or too hard (and I leak ego defending). What works: explicitly tell your partner what you're working on. "I'm drilling guard retention, please pass like you mean it but submit me only if I'm fully caught." Most reasonable men will dial in to that. What doesn't: being passive. They feel that, the rolls get weirder, you both leave frustrated.
Why I stopped trying to roll like the 25-year-olds at my gym
For 3 years at my gym I was trying to keep pace with the 22-year-olds doing 6-minute round-robins. I was hurt every other month. Then I switched: I let them attack, I worked frames, I conserved hips. I started winning more rolls. Got hurt zero times in the last 18 months. The technical shift was treating each roll like a chess game I'm playing slow. The pacing shift was harder — letting young dudes "win" the first 90 seconds without my ego flaring. Anyone else made this transition?
How do you teach the same technique to a 200-pound wrestler and a 110-pound new student in the same class?
Real problem I have every week. Same fundamentals class. The wrestler doesn't need help with the takedown but needs the framing detail. The new student needs the takedown more than the framing detail. What works for me: pair strangers on purpose. Wrestler partners with someone who can use the takedown coaching, new student partners with someone who patiently corrects the framing. But I still feel like I'm short-changing one or the other. Curious how other coaches think about this.
Mikey Musumeci's ADCC opening match is a clinic in pressure passing — annotated breakdown
I've watched this one maybe 30 times. The thing nobody mentions is how often Mikey is fighting from his knees on purpose. He uses the lower base to bait the underhook every single time. Three moments worth slowing down: 1. 0:38 — fake collar tie, drops to knees 2. 2:11 — knee shield bait into leg drag 3. 5:04 — backstep counter that should be in every flow Anyone teach this stuff at their gym? Curious how it travels.
Nicky Rod's scrambles look chaotic. They're not. Here's the pattern.
Every Nicky Rod match has the same 30-second window where it looks like he's losing position three times in a row. He isn't. Each apparent collapse is a setup for the next entry. The pattern: bait hip → frame off knee → re-shoot. It's ugly because his frame work is wide and his shots come from compromised angles, but the grip work underneath is clean. If you slow down his ADCC final, count how many times this pattern repeats. Then go look at his match before that. Same shape.
Best mouthguard for no-gi that doesn't make you drool
I've tried SISU, Shock Doctor, custom-fit from my dentist ($400). All of them either make me drool like a dog or fall out mid-roll. What are people actually wearing for 2-3 hour open mats?
How long is your fundamentals class? 6 months? 12? Forever?
I run a 6-month fundamentals cycle then graduate students into "all levels." Some coaches keep whites in fundies for years. What's working at your gym?
Is the 50/50 a real position or a defensive crutch by people who can't pass open guard?
The 50/50 stalemate killed several IBJJF finals. Lachlan Giles called it the "tax position." Most coaches teach it now as a defensive recovery. Is it a legitimate position with a finishing offense, or is it a stall pattern dressed up as technique? Honest takes from purple+.
How are you defending the wrestle-up at brown/black?
Everyone and their mother is hitting wrestle-up out of butterfly now. The Mikey Musumeci–style underhook stand-up is destroying my open guard. What are you doing — kimura grip threat? Hip switch to overhook? Dropping back to leg drag? Genuinely asking, getting smashed in training.
Heel hooks after 40 — yes, no, scared?
No-gi crowd is all leg locks now. I'm 41. My knees survived 15 years of jiujitsu. I'm not sure I want to risk them learning heels. Other 40+ folks: did you embrace heel hooks or stay away?
First year as black belt: what surprised you?
Got my black 11 months ago. Honestly — most of it has been the same as brown. Less anxiety, more "what now." Other black belts: what surprised you? Good and bad.
Closing out absolute at brown vs going for it — would you?
Final of brown absolute is me vs my training partner. We've closed out 3 tournaments already. Closer-out: smart. Going for it: respectful of the belt? What would you do?
Got my blue 6 months ago, getting smashed by lower-stripe blues. What gives?
I trained for 2 years for the blue. The 4-stripe whites at my gym were monsters. Now they're fresh blues and they cook me. Am I missing something or did I get a sandbagger blue?
Kade Ruotolo at lightweight vs Mikey Musumeci at lightweight — sub only, who taps who?
Both finishers. Both unhinged. Both lightweight royalty. Kade's scrambling and inverted attacks vs Mikey's berimbolo + leg-lock chain. My take: Kade has the engine for the first 15 min, Mikey has the patience for the last 15. Who closes?
White-to-blue: 22 months, 200 hours mat time. AMA
For everyone asking how long it takes — happy to break down what I trained, what I avoided, and what I'd do differently. Got the blue last week.
Brooklyn — 28F brown, want to drill leg locks 2x/week
No-gi only. Focused on inside heel hook entries from ashi/50-50. Not looking for a coach, looking for a partner who wants to grind the same position 100x. DM if you're serious.
When do you start specializing vs staying well-rounded?
I'm a purple. I've got an OK overall game but no real A-game. Every black belt I look up to has a SYSTEM. At what point should a purple commit to a system vs keep being a generalist?
ADCC trials vs IBJJF Worlds — where's the better path in 2026?
Talking to my comp guys about 2026 plans. ADCC trials are blowing up but IBJJF Worlds is still the most prestigious gold for sponsorship. If you had to pick one to peak for, which one and why?
Cross-training judo as a BJJ player — worth it for grips?
My takedowns are dogshit. Considering 2x/week judo at a place 15 min from my gym. Black belts who've done this — was it worth the time, or should I have just drilled wrestling shots and saved the commute?
Stalling at top half-guard at blue tournaments — talk to me about strategies
Every blue final I've been to ends with both guys clamped in half guard burning the clock. Refs aren't calling stalling. As the bottom guy, what's actually working to get out at the blue level? Drilling deep half hasn't cut it.
Female-only open mats — yes or no?
My gym started a women-only open mat once a month. Some guys complained it was "exclusive." Some women said it's the only time they actually push themselves. Where do you stand?
Fundamentals curriculum: closed guard first or open guard first?
Half my colleagues teach closed guard week 1. The other half say open guard is more useful for white belts in their first 6 months. What's your opening curriculum and why?
Stripes at white belt: do they actually mean anything?
I have 3 stripes on white. Friend at another gym is 4 stripes. We rolled. He destroyed me. Do stripes actually mean anything between gyms or is it all gym-specific?
Atos vs AOJ vs Checkmat — which lineage is producing the best black belts in 2026?
Atos: Galvao's shadow, but the team keeps producing. Tainan, Kaynan, the Mendes brothers got their belts here. AOJ: Mendes brothers' team, technical religion, but maybe peaked. Checkmat: Buchecha era was their peak. What's the pipeline now? Which academy is actually making more black belts who place at Worlds in 2026?
