Check out this great article from Atos HQ on the benefits of getting the whole family involved in BJJ.
Built in quality time and bonding time- Brazilian Jiu Jitsu is a positive thing to do with free time as a family. It also gives everyone something to practice outside of class together that encourages an active healthy lifestyle and a common interest for the family to share. The kids will be more likely to stick with it if the parents or at least one parent is training with them. Training can become a consistent time the whole family can hang out together and bond over a shared love for a sport.
Helps the family stay happy and healthy- The sense of achievement a person gets from doing Jiu Jitsu will make everyone more happy and confident. It keeps the mind and body active by providing a fun outlet to learn a new skill and it gives the whole family a fun new activity. It is important to have some kind of hobby to pour into that is not work related to get your mind off the stresses of life and Brazilian Jiu Jitsu is the perfect choice.
Traveling for competitions can double as a family vacation- Many times traveling is part of BJJ if the family starts getting involved in competing and this can be a great way to also get in some vacation time. Even if it is just a weekend get away it is a chance to make lasting memories as a family.
Support- You will better be able to motivate and help each other if everyone is training. Everyone can help each other with techniques they are having trouble with or help remember details that may have been forgotten. Understanding the sport better is especially helpful during competition. If the whole family is training together everyone will understand how the sport works and the best way to encourage one another in training and at tournaments.
