Professor Erik Klinger taught a packed Jiu Jitsu seminar this week at Gracie Barra Guatemala. Thank you Professor Lazaro Murcia and Gracie Barra Guatemala for your tremendous hospitality and generous donation of mats for our IJEF project in Quetzaltenango with Coach Oswaldo Vasquez and his Level Up Guatemala Jiu Jitsu school. Thank you also for a great training and class! Was a huge pleasure to share some techniques and training with you. Thank you so much!
