- 2 steps
A mobile, high-pressure control: drive a knee onto the belly and post up to attack or transition. Also known as the KOB, the Knee mount or the Knee ride. Here is the exact breakdown from the DARCE app: 2 steps, the details that make it work, and the mistakes to avoid.
When to use it
Use knee on belly from side control to add pressure and make the opponent move. It works when they frame hard on your chest, because standing up takes the frame away. Each time they push on the knee, an arm comes free for an armbar or a choke.
Step by step
- 01
Side control
Establish chest-to-chest side control.
- 02
Drive the knee up
Slide your near knee onto their belly, post the other foot out wide and posture up tall, hands controlling the collar/hip.
Key details
- Drive the knee into the soft of the belly and sit your weight onto it.
- Post the outside foot wide for a stable, mobile base.
- Stay tall and heavy. KOB pressures them into mistakes to attack.
Common mistakes
- Kneeling on the hip or chest instead of the belly.
- Keeping the base narrow and getting bucked off.
- Sitting low instead of posturing tall over the knee.
Common counters
Opponents push the knee off their belly, shrimp away to make space, or grab your leg and turn in to recover guard. A narrow base gets bucked off. Stay tall, keep the outside foot wide and switch to mount or side control as they move.
How to drill it
From side control, step up to knee on belly and back down, ten reps on each side. Then do three rounds of one minute where your partner tries to escape and you follow them with knee on belly, mount and side control.
