Knee on Belly Control
Knee on belly is a control most students don't feel confident holding — the Journey Score data says so. Set it up properly: leg across their hips, find your base, and answer every reaction by adding weight in the right place.
1. Objectives & Mechanics
Set the control properly: your leg goes across their hips and you find your base. Every escape attempt — rolling into you, rolling away, bumping — has the same answer: add weight in the right place.
2. Submissions — the cross collar choke
Knee on belly affords multiple submissions. For the basic cross collar choke: create space to get a deep grip on the collars and set the choke up by maintaining pressure — but to finish, put both knees on the floor.
3. How to practice
Partner rolls into you: add weight in the right place. Rolls away: same. Bumps: same. Then practise the transition from knee on belly to mount.
