From the reviews

Update: 3.5 years later, both of my children and my husband train here now and they love it. It's become like a little family for them. Hoping to join when my schedule gets less hectic. Still 5 stars all the way Original: my son has been coming here a little over two months now, and I couldn't be happier.

Great place to train jiu-jitsu! Authentic black belt instruction with a family environment. The training is fun and challenging at the same time. Recently moved to a new location that is spacious and clean. Being a woman training in Jiu-Jitsu I was welcomed and always felt comfortable training at this academy!

★★★★★ — Kristina, Apr 2017

I started training about 6 weeks ago with absolutely no experience at all. Each fundamentals class is presented as if everyone is hearing it for the first time, so I never felt left behind. Everyone has been extremely welcoming and I look forward to going back each week. Thinking about getting the kids involved, too!

★★★★★ — Jessica, Mar 2023

My dad, brother, and I have been training here for almost 8 years. Hassett's Jiu-Jitsu is a great place to learn and train. The environment is always friendly and encouraging. You can be confident walking through the doors that you're in for a great class.

New to BJJ? Start at Hassetts Jiu-Jitsu Williamstown

Hassetts Jiu-Jitsu Williamstown comes up as a beginner-friendly gym, going by their listing and members’ reviews. If you've never rolled or set foot on a mat, that's exactly who a good beginners program is for. A few things worth knowing before your first week. First, you don't need to be fit or flexible to start — you get in shape by training, not before it, and coaches scale the intensity to you. Second, you won't be thrown into hard rolling — reputable gyms build fundamentals (positions, escapes, and basic submissions) for weeks, live rolling eases in gradually, and tapping early keeps every roll safe. Third, all levels really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out, and leave your ego at the door. Most gyms are happy to let you watch or try a class first, so reach out before you commit.

Your first BJJ class at Hassetts Jiu-Jitsu Williamstown

Nervous about walking into a BJJ gym for the first time? Almost everyone is, and good coaches expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling basic positions and escapes with a partner — not hard sparring. Rest whenever you need to; no one will bat an eye. What to wear: athletic wear you can move in (or a gi if you have one); you'll train barefoot on the mats. What to bring: water and a mouthguard if you have one — many gyms lend a loaner gi for a first class, so it's worth asking when you call. As you keep training you'll add your own gi (or a rashguard and shorts for no-gi) and a mouthguard. Live rolling eases in gradually, once your fundamentals are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.

BJJ is a contact sport. Ease in, tap early and often, listen to your coaches, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
