In this episode I put on my adventurer hat and use my biology background to look at four studies and 352 aggressive bear encounters in Alaska to see whether bear spray or firearms was more effective at deterring aggressive black, grizzly and polar bear behaviour. The results may surprise you, but data doesn't care about your feelings!  TIMESTAMPS 01:28 - Introduction to bears spray vs guns 04:08 - Analysis of the first report, Bear Spray vs Bullets, Which Offers Better Protection, by the...

There are times when it feels like life has you trapped on the bottom of mount against a vastly heavier, more experienced opponent intent on mauling you.  The steps to deal with these two situations are the same.   Pass this on to someone you think it might help, Stephan Kesting P.S.  I made one little mistake in this podcast: Epictetus was a Greek (not Roman) stoic philosopher who lived in Rome for much of his youth serving the Emperor Nero, so he doubtless knew all about suffering.

I really enjoyed talking with Rachel Honeyman about modifying BJJ for self defense, which techniques to focus on and which positions to avoid.  Rachel has trained in BJJ, the Filipino Martial Arts, Muay Thai, and many other martial arts and runs https://www.fearlessfemmes.com/

Rob Biernacki is my guest today to talk about how injury and physical limitations have led to some of the fastest technical development of his career and the refinement of entirely new techniques like the Roadhouse Choke.  Since some form of injury is inevitable there are a LOT of takeaways in this episode. We also discuss the concepts of risk vs reward in your choice of techniques, how new techniques and technical refinements get adopted, the risks of the buggy choke, the barbell strategy...

Many people completely run out of gas when they're sparring, and often this is because they are inadvertently holding their breath.  In this short podcast I share four very specific ways that I've coached people past this problem and hugely improved their endurance. Please share this episode with someone you think it will help. Cheers, Stephan Kesting P.S. This episode is also available in video form here: https://www.youtube.com/watch?v=umD_zc5Bd3M P.P.S.

The traditional class structure of doing a warmup, learning a couple of new techniques, and followed by sparring is NOT an efficient way to learn jiu-jitsu.  We can do much better if we use insights from research on coaching and learning. Today's guest is Cal MacDonald, a BJJ black belt and  competitor who has dedicated himself to developing his teaching and coaching skills to the highest possible level.   Cal is a longtime blackbelt under Rob Biernacki at Island Top Team. Rob and his team...

Satoro Sayama and the birth of Shootwrestling... American vs British catchwrestling... the blending of...

Rob Biernacki and his competition team are on a tear. Rob recently took gold in masters middleweight the Canadian ADCC Open, silver at the California ADCC Open, and gold in black belt M4 at the IBJJF No Gi Worlds. In this episode we talk about designing an effective training camp, dividing your conditioning and skills training, detaching emotionally from the outcome of the competition, why sharktanking and competition-style rolls are overused, 80/20 analyses of different rule sets, training...

Topics we cover include the origins of boxing in England, historical training and conditioning methods, reconstructing and testing techniques shown in swordfighting manuals, fighting with live blades, the role of wrestling in real swordfighting, and much more.  I think you'll really like this one! Oz Austwick runs the English Martial Arts channel on...

Today I pick the brain of the amazing Jost Kobusch is a German mountaineer who spent two seasons on Everest trying to ascend the legendarily difficult West Ridge route and the Hornbein Couloir alone. And did I mention that he wasn't using supplemental oxygen and attempting this in the middle of the brutal Himalayan winter?  We covered a TON of interesting topics, including Why do things the hardest way? His closest call in the mountains The dangers of the Khumbu Icefall Getting hit by an...

With eyewitness testimony in the US Congress and purported alien bodies being wheeled into the Mexican Congress, it looks like we're in another UFO craze right now.  It was great to have science writer and sceptical investigator Mick West on the podcast to make sense of this evidence and evaluate what the odds are that aliens truly walk among us.     Check out Mick's current research at metabunk.org, it's my first stop for anything UFO-related.   Check out the video of this conversation...

I caught up with world record holder James Pieratt shortly after he completed a 500-mile, self-supported mountain run along the Pacific Crest Trail.  But James isn't just an ultrarunner - he's also a serious weightlifter who also trains in jiu-jitsu. In this interview we went deep into how to balance strength, endurance, and skill training, the role of prehabilitation and rehabilitation, the effect of hard training on life expectancy, and what drives someone to these extremes.  Check out...

The Ultimate Self-Defense Championship was a competition in which six martial arts YouTubers competed against each other in seven self-defense challenges to find out what works, what doesn't and who would become the ultimate self-defense champion.  The organizer of this event was Rokas Leo who trained Aikido for 14 years and eventually realised that that art didn't live up to what to the promises. He made the switch to MMA training and has had several amateur MMA fights since.   My previous...

Not only is Robert Drysdale a BJJ and ADCC World Champion, he has also conducted extensive research into the history of Brazilian Jiu-Jitsu. In this interview, he reveals some of what he's discovered, including... 01:54 - The first wave of jiu-jitsu in Brazil - Helio Gracie and Carlos Gracie  04:35 - Exhibition and carnival fighting in Brazil 06:55 - Traditional jiu-jitsu style vs modified judo 12:14 - Training methods of the Gracie Academy in the '30s, 40s and '50s 18:43 - The second...

Carlson Gracie fought in 18 Vale Tudo matches, brought jiu-jitsu to the masses, and innovated many of the MMA training practices we now take for granted. He innovated many seemingly radical ideas at the time, like training without the gi, group classes, and being a well rounded fighter. These points come from Robert Drysdale's excellent book, The Rise and Evolution of Brazilian Jiu-Jitsu, available on Amazon at ...

The jiu-jitsu world was shaken recently when Jack Greener, severely injured in 2018 while sparring at a San Diego gym, was awarded $46,475,112 dollars by a jury. Rener Gracie testified for the plaintiff, and Clark Gracie testified for the defence. In this episode, I get together with Dan Lukeheart (Brea Jiu-Jitsu) and Alex Kask (Barrister and Solicitor) to discuss the specific technique that caused this injury (the 'Leo Viera Backtake'), training methods used in jiu-jitsu, who gets to set...

Jesse Bryant is doing his PhD on the politics of nature, and has come across some amazing examples of both far left and far right groups wrapping themselves in the mantle of nature and what is deemed 'natural'.  From the Artaman League to the Wolves of Vinland and Alex Jone's fantasies about moving back to the country sometimes what he's found is hilarious, and sometimes it's terrifying.  I really enjoyed today's homage to the Naturalistic Fallacy and I hope you do too... Check out Jesse's...

Amanda Bruse took home Gold as a black belt in her weight division at No Gi Pans in 2022, and also a Silver in the open division facing much heavier opponents. She's also done amazingly well at ADCC Trials, No Gi Worlds, and is now competing in Combat Jiu-jitsu as well. It's remarkable that she's only been training for 6 years; clearly, she's doing something right, and in this conversation I try to find out what it is!! Tune in to find out about learning how to train (02:48), her favorite...

To say that Greg Souders is a huge believer in drilling and gamification is actually an understatement; he believes that BJJ training methods have not kept up with the science of learning, and runs Standard Jiu-Jitsu in Rockville, Maryland without teaching any techniques. And black belt medalist students at the Pan Ams and the World Championships suggest that he's onto something!  I really enjoyed this conversation and did my best to ask the questions you'll be hearing in your own head as...
