It is possible to train Brazilian Jiu-Jitsu (BJJ) at home, but it comes with certain limitations. BJJ is a highly physical and interactive martial art that involves grappling and close-quarter combat, which can be challenging to replicate in a home environment without suitable training partners. However, there are still ways to supplement your training at home such as solo drills, studying instructional videos, working on strength and conditioning exercises, and practicing specific techniques on a grappling dummy. While these methods can help improve your overall understanding of BJJ, they should never replace regular training at a proper BJJ gym with experienced instructors and training partners.
