A community for practicing, discussing, and exploring grappling with the Corbe Brothers. Black Box Online is where we share how we actually train and coach drawing from 20 years of grappling experience and our time competing at ADCC, CJI and WNO. This space is for grapplers at all levels who want interactive, functional systems, real training footage, and sessions that hold up on the mat. Everything here reflects how we think about practice design, decision-making, and long-term development. Membership access includes: • Live training footage showing real implementation • Weekly breakdowns of constraint-led training games with clear explanations • Recorded seminars covering systems, practice design, and decision-making • Direct coaching access through group and 1-on-1 calls \(tier dependent\) • Higher-level options for full practice design and ongoing guidance
