Mateo and Xyla have been with us for a very long time and are two of the hardest working kids on the mat. Their Jiu Jitsu is also top notch due to it. Because of this Coach Jocelyn and I found it fitting and deserving to level them both us today! Congrats you guys, we’re so very proud of you both! Keep up the great work! 💪🏽🥋🦍🇺🇸🇧🇷.

THIS is what kids’ Jiu Jitsu should look like. 🥋❤️

What an awesome class today at 148 Jiu Jitsu! The mats were packed, the energy was high, and most importantly — there were a whole lot of happy faces!

Yes, we teach Jiu Jitsu. We teach technique, discipline, respect, confidence, and how to become comfortable in uncomfortable situations.

But they’re also KIDS… and kids need to have FUN!

So after putting in the work today, we finished class with a little JIU JITSU BASEBALL! ⚾️🥋😂

The yelling, the laughing, the competition, and especially the smiles were exactly what this academy is supposed to be about.

Some of these kids may become champions. Some may train for years. Some may simply look back one day and remember the friendships they made and how much fun they had on these mats.

ALL OF THOSE ARE WINS. ❤️

I’m proud of every one of these kids and incredibly grateful for our coaches and families who continue to make 148 Jiu Jitsu such a special place.

Train hard. Have fun. Be a good human being.

See you on the mats! 👊🏽🥋

🥋 STRONG GIRLS. CONFIDENT GIRLS. FUTURE LEADERS. 🥋

There’s something special about seeing young girls step onto the mats and learn that they are stronger and more capable than they realize.

Jiu Jitsu teaches them how to fall and get back up. How to stay calm when things get uncomfortable.
How to solve problems instead of panic. How to be confident without being arrogant.
And most importantly, how to believe in themselves.

For little girls especially, learning that they can protect themselves, use their voice, establish boundaries, and stand their ground is something they can carry with them for the rest of their lives.

We aren’t just teaching these girls armbars, escapes, takedowns and submissions.

We’re helping raise strong, disciplined, confident young women who know they can handle hard things.

Someday they may forget a technique we taught them, but I hope they never forget the feeling of walking onto these mats and discovering just how POWERFUL they really are. ❤️🥋

This is why we teach. This is why Jiu Jitsu matters. Thank you Coach JGraceSoares and Coach Mika Kameda for leading the way! 💪🏽🎀🥋🇺🇸🇧🇷

Today we did something a little different at JJM/148. We invited our students to bring their parent or guardian onto the mat to experience class with them. They did warm ups, drills, sparing and even got to experience Jiu Jitsu baseball. The kids of course won 9 to 1! It was a great time and the parents realized that Jiu Jitsu isn’t easy but it can be fun! Thank you to all the parents and guardians who stepped on the mats today and showed your kiddos how much you care! 🙏🏽❤️🥋🇺🇸🇧🇷. Jean Jacques Machado

Yesterday was bitter sweet, It was Professor Adam Florendo last day as an instructor but he’s leaving to go start some cool and exciting new things! We want to wish him well and nothing but success in his new journey. It’s definitely not goodbye as he will be coming in from time to time for training and to raid the snack bin for bags of Cheez-it’s! 🙏🏽❤️🥋🇺🇸🇧🇷
