A really good place to workout and learn fighting techniques varying from self defense to situational scenarios that could be presented at any point in day-to-day interactions. One of the head trainers, Cornelius, is a phenomenal trainer who enjoys his work and has a great track record to back him. He’s knowledgeable on JKD and is going to put your development and success over everything else in training sessions. Great overall gym. More...

Dublin California JKD offers awesome life benefits. It's such an honor to be trained by Cornelius Barnes who is not only a master at what he does, he's also excellent at teaching these techniques. He makes sure you understand how and why these fighting skills work, and restrains your mindset as well by showing you a different perspective of potentially threatening situations. He shows you that you have tools of defense that you were born with, and he teaches you how to use them. This builds your confidence, which makes you stronger physically and mentally and in turn helps to give you peace of mind. It is such an honor too be a student of such awesome and life benefiting training! More...

Cornelius is fantastic. The training sessions are really interesting and makes a lot of difference. Cornelius ensures that we remain motivated and not get bored of having similar routine in the gym. It’s a really wonderful place.
