Cross-Side to Mount: The Knee Over Belly Pass
In Brazilian Jiu-Jitsu there is more than one road to the same destination. We already walked through the step-over pass to mount — and this guide is its twin. Same starting point in cross-side (side control), same goal of climbing to the mount, but a different vehicle to get there: the knee over belly. When your opponent defends the step-over well, the knee slide is the answer waiting on the other side.
In this beginner guide, filmed again with Senior Professor Ed Shobe at Legacy BJJ Omaha, we break the knee over belly down piece by piece so you understand not just what to do, but why each step works. If this transition is on your white belt stripe test, study this alongside the step-over guide so you can show both.

Same Start, Different Finish

If you watched the step-over guide, the opening here will feel familiar — and that is the point. Both passes begin the exact same way, because both depend on the same two problems being solved first: clearing their inside arm off your hip and controlling the elbow closest to you.
So before you think about your knee going anywhere, take the same read you always take from the top. Their inside arm is framing into your hip, looking for space to recover guard. Until that arm is dealt with and that elbow is pinned, any attempt to travel just hands them the room they want. The knee over belly is not a different beginning — it is a different ending to the same beginning.
Lock the Elbow and Win the Crossface
Set it up exactly like before. Grab the gi and pull back while you drive shoulder pressure into the side of their head, steering their face away from you. That pull-and-drive is the engine — you are not shoving with your arms, you are using your shoulder and a tight grip to turn their head. When the head turns, the hips follow.
As the pressure lands, dip below their near elbow and come back up to break the frame and secure the elbow closest to you. Nothing moves until that elbow is yours. This is the same “connection and weight distribution” principle that runs through our Team Vaghi lineage — control comes from where your weight lives, not from muscle.
Shift Your Hips and Turn Them to Their Side

With the elbow controlled and the pressure set, change your hips and turn toward their legs — the same hip shift from the last pass. Keep your weight pinning the shoulder so they cannot turn into you. From there, reach down to grab their leg and drive them sideways, away from you, rolling them up onto their side.
This is the fork in the road. In the step-over pass you pulled the knees across and stepped over the arm. Here, putting them on their side sets up a completely different finish — one where your knee, not your foot, does the traveling.
Leg Weave and Plant on the Hip
Once they are turned onto their side, control the legs with a leg weave — your hand threads in between their top and bottom leg so they cannot reconnect their knees and rebuild guard. That weave is your insurance: it keeps their lower body split while your upper body stays heavy.
Now place your leg on their hip, right around the belly-button line. This is your platform. Your shin and foot on that hip are what let you over belly your knee across in the next step without losing the pin — and just as importantly, they keep your opponent’s hips flat so they cannot shrimp away underneath you.
Slide the Knee Across

This is the pass. Slide your knee across to the ground while keeping the pressure of your back foot on their hip. That detail is the whole trick: if your foot leaves the hip, they trap it and you are stuck in half guard. Keeping the foot heavy on the hip means there is nothing for them to catch as your knee travels to the mat.
As you slide, post your head on the ground across from their face. Your head is your kickstand here — posting it on the far side balances you so you do not get rolled while your base is briefly split between the slide and the pin. Knee to the floor, foot still pressuring, head posted: that is the moment the pass is won.
Drag the Arm and Climb to Mount
The instant you land, go to work on the near arm. Reach under their arm and drag it up toward their head. This does two jobs at once: it sets up a submission, and it strips away the frame they would otherwise use to stop your hips from finishing.
With the arm dragged up and out of the way, pull them onto their side, drop your foot down across their body, and settle into mount. Stay heavy through the whole climb — do not rise up to “stand” into the position, or you give back the very space you just took. Land connected and the mount is yours.
What You’ll Be Judged On at Stripe Testing
If you are running this for your first stripe test, your coaches are watching for control and intent more than speed. Expect to be evaluated on whether you:
- Clear the inside arm and control the near elbow before you travel — same as the step-over pass.
- Set the crossface first — pressure, then movement.
- Use a real leg weave — hand between the top and bottom leg, not just a loose grip.
- Keep back-foot pressure on the hip the entire time your knee is sliding.
- Post your head across from their face for balance and finish heavy in mount.
Common Beginner Mistakes
A few errors show up again and again. Letting the foot leave the hip as the knee over belly is the big one — that is exactly the gap your partner needs to trap your foot and stall you in half guard. Skipping the leg weave lets them reconnect their knees and rebuild guard before you ever get moving. And coming up too high as you land lightens your weight at the worst moment, which is precisely when a good escape lives. Slow it down, stay heavy, and trust the sequence: pressure, elbow, hips, weave, knee over belly, mount.
Drill It, Then Roll It
Reps build instinct. Drill it slowly with a cooperative partner: clear the arm, set the crossface, shift the hips, turn them to their side, weave the leg, plant on the hip, slide the knee with the foot still pinning, post the head, drag the arm, and climb — ten clean reps per side before you ever try it live. Then learn its twin: the step-over pass to mount is the companion answer when your opponent shuts the knee slide down.
