Do I need to be in shape to start BJJ?

No! BJJ will get you in shape. We welcome people of all fitness levels and design our beginner classes to be accessible while still providing a great workout.

What should I wear to my first class?

For your first class, comfortable athletic clothes (t-shirt and shorts or athletic pants) work fine. We provide loaner gis and equipment for beginners. Eventually, you’ll want your own gi for gi classes and a rash guard for no-gi.

Will I get hurt training BJJ?

Safety is always prioritized. Minor bumps and bruises may occur, but safety is always prioritized. Our coaches are there to teach and reinforce proper technique and control. Training partners are matched by experience level.

How often should I train as a beginner?

We recommend 2-3 classes per week to start. This gives your body time to recover while maintaining consistent progress. As you advance, you may choose to train more frequently.

Can I try a class before committing?

Absolutely! We offer a free trial week so you can experience our classes, meet our coaches, and see if Diamondheart is the right fit for you. No commitment required.

What is Brazilian Jiu-Jitsu?

Brazilian Jiu-Jitsu (BJJ) is a martial art and combat sport that focuses on grappling and ground fighting. Unlike striking arts, BJJ teaches you to control and submit opponents using leverage and technique rather than strength or size.

This makes BJJ particularly effective for self-defense, as it lets smaller practitioners to defend themselves against larger opponents. BJJ focuses on ground-level encounters, using holds, throws, joint locks, and chokes to neutralize threats without necessarily causing harm.

Beyond self-defense, BJJ is known for building physical fitness, mental resilience, problem-solving skills, and a strong sense of community among practitioners.
