The best way to learn Brazilian jiu-jitsu is to take classes at a reputable training school so that an experienced instructor can show you proper form and technique. If you aren't able to take classes, you could learn the basic movements from handbooks or video tutorials.

There are five fundamental positions in Brazilian Jiu-Jitsu: guard, half-guard, side control, mount, and back control. The guard is a defensive position in which the Brazilian Jiu-Jitsu practitioner is on their back, with their legs wrapped around the opponent.

The most common way for beginners to learn Brazilian Jiu-Jitsu is to start with the basics of sparring, building up their fitness and endurance before starting to learn grappling and submission techniques.
