Jiu Jitsu is best learned in a group setting because of the diversity provided in having different training partners.  However, private classes are defiantly an essential supplement for anyone that is serious about elevating their skills in an intensive setting. The one on one focus of a 30 or 60-minute private session will provide much more insight into any problems or challenges you may be facing in your Jiu Jitsu. To help you improve in a much faster timely fashion, it’s highly recommended that every advanced student take one private lesson per month.
