What is the difference between gi and no-gi BJJ?

In gi training, you can grab collars, sleeves, and pants to control your opponent, which opens up a wide variety of chokes and sweeps not available without the uniform. No-gi relies more on body control through underhooks, overhooks, and wrist control. No-gi tends to be faster-paced because the lack of friction makes it harder to hold positions. Many practitioners train both styles because each develops different attributes. Gi training builds grip strength and teaches patience, while no-gi develops speed, scrambling ability, and translates more directly to MMA. Most coaches recommend training both, especially as a beginner, to develop a well-rounded game.
