Why Start Adult BJJ at 40? Just Ask Mike.

Starting Brazilian Jiu Jitsu in Your 40s

If you're considering starting adult BJJ (Brazilian Jiu Jitsu) in your 30s, 40s, 50s or later, this post may help you to muster the courage to start your first free trial at Watermark Brazilian Jiu Jitsu - where we encourage all students of all ages and all skill levels to feel comfortable and enjoy the benefits of this amazing martial art.

In this post we share one new student's story and combine another factor he considered before trying adult BJJ - the influence of a Jocko podcast.

Why Start Adult BJJ at 47? Because Mike Did!

There’s a moment that happens on the mat—usually after you’ve survived your first real round of sparring—when you realize this isn’t just a workout. It’s a mindset shift. And for many adults starting BJJ later in life, that moment comes with a mix of exhaustion and clarity. It’s what keeps them coming back. Just ask Mike.

Meet Mike: 47, Full-Time Job, Full-Time Grit

Mike didn’t grow up wrestling or striking. At 47, he’s got a demanding job, a family, and a body that remembers the more physically fit days of his 20's that feel out-of-reach approaching 50. But what he found in adult BJJ was something he didn’t expect—progress. Real, measurable progress. In this Instagram video, you’ll see Mike hitting sweeps, escaping tough positions, and holding his own with students of all ages and skill levels. But more importantly, you’ll see a man who decided not to give up on his health, confidence, and learning curve just because he was “too old.”

Jocko Willink on Adult BJJ in Your 40s

Mike isn’t alone and he was also influenced by one of his favorite podcasters and famous advocate of BJJ, Jocko. In one of his podcast episodes Should I Start Jiu Jitsu Later in Life? - Jocko Willink, Jocko Willink—a black belt, Navy SEAL, and respected leadership coach—said:

“You’re 40? Perfect. You’ve got discipline, patience, and probably fewer ego problems than most 20-year-olds. Jiu jitsu isn’t about who’s fastest—it’s about who shows up.”

Jocko often reminds listeners that starting adult BJJ later in life isn’t a disadvantage—it’s an asset. Adults bring focus, self-awareness, and a desire to improve, not just dominate. Plus, BJJ offers what many adults are missing: connection, challenge, and stress relief that doesn’t come in a pill bottle.

What to Expect from Adult BJJ

  • It will be humbling: You’ll get tapped. A lot. That’s part of the learning.
  • You’ll improve quickly: Not because you’re athletic, but because you’re consistent.
  • Your body will change: Flexibility, strength, coordination—yes, even in your 40s.
  • You’ll make friends: The kind you trust to choke you one round and high-five you the next.

Adult BJJ: You’re Not Too Old. You’re Just Getting Started.

If you're an adult tired of going to 24-hour gyms and having to come up with your own fitness plan over and over or suffer from the boredom of a stale routine. If you're sick of trying to muster the self-discipline and right playlist to run a 10K (not to mention the beating on your meniscus and plantar fascia). Then you should be thinking about trying adult BJJ and telling yourself it’s not too late—let Mike be proof of that. Whether you’re 35, 47, or 58, there’s a place for you on the mat at Watermark BJJ. And it starts with one class. One tap. One breakthrough.
