Extended Summary:
Jiu-jitsu is a close-contact art — so hygiene and mutual respect are paramount. Always come to class freshly bathed, with trimmed fingernails and toenails. Wash your gi after every training session. Don’t train if you’re sick or have skin infections. Etiquette matters too: bow when entering the mat, show respect to everybody, this means instructors AND training partners, and be helpful to lower ranks. Most importantly, leave your ego (and your shoes) at the door — tapping isn’t losing; it’s learning. Don’t resist at the cost of injury. Be coachable, be safe, and foster a welcoming mat culture. That’s how everyone gets better — together.
