Sheri Hockman started her journey in 2002.  Jiu-Jitsu requires an incredible commitment to achieve black belt, added to that the fact that currently it is a male dominated sport.  It is with that in mind that we celebrate with Sheri and congratulate her on this amazing accomplishment.  Sheri was promoted by Rosendo Diaz on August 22 at the annual 3rd Generation Jiu-Jitsu Team promotion Ceremony.

BJJ and Yoga practice go hand in hand.  The combination of flexibility and strengthening of your core cannot be matched.  I would recommend to all my friends that if you live or work near the King Of Prussia area you check out The Yoga Den.  Recently had the opportunity to attend a hot yoga class.  Having trained at various yoga studios over the last 7 years I can tell you that the Yoga Den’s class was by far one of the best I’ve ever attended.   Knowledgeable, hands on instructors, well paced classes and a facility that is unmatched in the area.
