Welcome to Sumo! Before you can attempt a takedown make sure you can control the chaos!

Congrats to Karen and Dan on earning their Blue Belts! @ Mass BJJ

Manage distance, just keep fighting. We just wrapped up a week of striking in all of our BJJ classes. I know that most people have no interest in getting in the cage for an MMA fight but it is crucial that our Jiu-Jitsu is effective when dealing with an aggressor that is striking.

When our opponent is striking, our priorities shift. Controlling the distance between us and our opponent becomes one of our top priorities.

The second big lesson was, “just keep fighting”. It doesn’t matter if you just got hit or you don’t know what exactly the right technique is to do next. If you stop, you are done, just keep moving.

Many of us were inspired to start Jiu-Jitsu after watching Royce Gracie defeat fighters of all different styles of martial arts. I know most people don’t want to jump in a cage and take a professional mma fight. But I never want us to lose the base of the art. It is my hope that all of our students feel comfortable and confident that what they are doing will work for them if someone does come after them with strikes. The only way to know that, is to get someone on top of you and have them punch away. (with control!)

[05/27/19]   Reminder that our open mat is Monday from 12:00-1:30pm. We will be grilling and eating afterwards. Everyone is welcome to come train and we always have a lot of families and kids playing outside all afternoon. There is an event page already set where people are posting what food they will bring. See you on the mat!

[04/20/19]   No classes on Easter Sunday. Instead, 6 sets 20 seconds of burpees with 10 seconds rest!

Highlights from our vacation program... what a fun week! This was our largest group yet and we had a range of ages (5 - 14). We worked on our jiu-jitsu, played a bunch of games, watched A Wrinkle in Time, introduced the teens to striking and no-gi BJJ, and more. These guys put in a lot of hard work and had a lot of fun! Thanks for joining us 😁

Summer Programs: June 24th-27th and August 19th-22nd

First in 10:30am, last out 8:30pm. Taking Pat’s advice, “If I had that problem, I’d just train more.”

Thanks to Ron for having me up to Lawrence High School to see one of his Jiu-Jitsu classes! Lawrence is one of the few/only public schools that I know if to offer Jiu-Jitsu as a class. This is one of the four, hour and a half long BJJ classes that Ron will be teaching today!

On a daily basis, I only really see the world that I have around me at Mass BJJ. To go to Lawrence and see all these kids that Ron is trying to reach through Jiu-Jitsu was truly inspiring for me! Thanks for allowing me to be a part of Lancer Jiu-Jitsu , keep up the good work and now I know why you look so tired some nights when you come in for your training!

Congrats to Alice on earning her purple belt! I made Alice do warm ups for class. She did such a better job than Frenchy I had to surprise her with her purple belt! I’ve taken many pictured with students to celebrate their belt promotion. Alice was the first “Adult” to give me bunny ears during that picture. I did what I try to do every time we roll and choked her with her pony tail. Alice did what she does every time we roll and elbowed me in the face! Congrats Alice! @ Mass BJJ

We're only a few weeks away from April vacation - register your students today!

We appreciate everyone's feedback and have updated our program based on some of your suggestions- students can now do 1, 2, 3, or 4 days and we've split up age groups, added a fourth instructor, and have a few new things in store!

Please contact [email protected] with any questions.

Congratulations to Dan Phoenix. Brown Belt, Featherweight, Masters, Pan American Champion.

Congrats to Rob on earning his blue belt and Brad on his Brown belt! @ Mass BJJ

Congratulations to everyone promoted tonight! This group worked so hard studying, drilling and rolling together to prepare themselves to take the next step. I have been very proud to see you guys coming together as a team and a community, to better yourselves and help your teammates get better. Jiu-Jitsu is a great art, a great way of life, and it’s so much better when you have great people around you! (All the individual promotion pictures are up on Facebook as Instagram caps the amount of pictures we can put in one post.) @ Mass BJJ
