We believe challenge is the only path to growth. There is a spark flickering inside of you – All you need to do is turn
it into a flame.
Which is why I'd like you to attend our famous SEALFIT Crucibles, you will take on the biggest physical and mental challenge you have ever faced. When you finish, that little spark will turn into a raging fire.
You’ll feel invincible moving into 2023, and your brain and body will be ready to conquer your goals moving forward.

A SEALFIT Crucible marks the beginning of your transformative journey
What is a SEALFIT Crucible?
SEALFIT Crucibles are premium, in-person, transformative events. We bring together a small group of determined people who are sick of not being challenged and we give them the challenge of a lifetime.
Born out of NAVY SEAL training philosophy, Mark Divine and a group of military experts lead Crucible members through a 6, 12, 24, or 50-hour boot camp in the ultimate test of physical and mental willpower.
Finish the Crucible and you’ll come out a completely different person – for the better.
IT Pays To Be a
Winner
When you finish a Crucible, the lessons learned will ripple out over all aspects of your life:
- You will become a better parent in the home.
- You will become a more refined professional in your work.
-
You’ll become fitter, stronger, and healthier in the process.
- And most importantly, your mind will be seasoned for any difficult work that lies ahead.
Our members go through this challenge because they want to be better.
Crucible finishers are a different breed. They are not common.
They don’t play by the rules, and they certainly don’t let failure be the end of the story. In the Crucible graduating classes, you’ll find future NAVY SEALs, veterans, elite entrepreneurs, kick-ass parents, serious fitness junkies, and everyday civilians looking for the challenge of a lifetime.
If you want to accomplish 20X more than you ever thought possible, conquer your inner demons, and embrace the suck with us, SEALFIT Crucibles are perfect for you.

The 20X CrucibleS
These crucibles are broken down in 6, 12 or 24-Hour events, and are designed to be difficult yet attainable for any motivated, physically healthy person.
This is a physically focused “crucible” challenge for both individuals and teams, that will prove you are 20 times more capable than you think you are.
Experience a permanent shift in your perspective and way of life by taking part in the 6, 12 or 24-Hour Crucible where our elite SEALFIT coaches – including active and retired Navy SEALs – will push you beyond your perceived limits.
This event is not for everyone.
Our Navy SEAL and Special Operations coaches will push your physical limits, build on your strengths and uncover your weaknesses.
This is not a mindless physical “beatdown.” Our SEALFIT coaches will use their years of Special Operations Forces training and experience to give you the tools you need to overcome any obstacle, eradicate fear and tame your mind.
This Crucible is only for those who are ready to take on intense physical challenges and are ready for real change.

Graduates SPEAK
"You’ve created an amazing life experience and I’m honored and grateful to have had the opportunity to live it. I draw on the experience every day in so many aspects of my life —in my thinking and reflection, relationships, training, teaching and coaching, pro-action/action/reaction, business, etc. While I’ve completed some relatively sizable endurance events in the past…none of those experiences comes even close the holistic takeaway from Kokoro Camp. Not even close."
JEFF, KOKORO CAMP 13
"I was one of the Spring 2014 classmates for the SEALFIT 20X challenge. I just wanted to thank you for this great opportunity. There isn’t a price that could be made to account for all SEALFIT taught me. I can honestly say I feel like I can capture the world and become anything I put my mind to. I am truly blessed to be in control of my entire mind."
MICHAEL HALL
"Four weeks ago a friend asked if I wanted a number to run in the Boston marathon. I hadn’t been training for a marathon but I was up for it. And in order to raise money for his charity I offered to do 10 push-ups at each of the race’s 42 kilometer points. Long story short I finished and did 450 push-ups. Took me 6:20 but I did it. People asked me what made me think I could do it and I said 20x. Plain and simple. So thanks."
STEVE
"I am not the same person after Kokoro. The experiences I had during Kokoro 29 have completely and permanently changed me in very powerful ways – for the better. I am not the same person I once was and I’m proud to say I have been forged into a stronger man. Hooyah!"
LOREN L.
"Preparing for and completing Kokoro camp was the best thing to ever happen to me. I was able to learn more about myself this summer than some people may ever learn about themselves in a lifetime. It has not only made me a better leader for my teammates, but a better leader of my own life. I find myself making better and more and confident decisions. I’m not as easily flustered as I was before. Each day of my life I use something I learned at Kokoro to my advantage. My coach has told that I “no longer run from challenges, but rather run straight at them. I strongly encourage anyone who is thinking of doing Kokoro to just go for it. It will change your life and teach you things about yourself that you may not be able to imagine. I now crave life’s challenges and look to push myself outside of my comfort zone. Like I tell everyone who has asked me about Kokoro: If I can make it through, so can you."
MCCALL TOMENY, KOKORO 29
