Knee Slice to Side Control: A Complete Guide
Quick Intro
Knee Slice to Side Control is a Martial Arts Drills exercise performed by completing the knee slice guard pass through to fully established side control, flattening a partner’s hips and pinning the far-side shoulder and hip. Flattening the partner’s hips to the mat before settling into side control is what makes this pass secure.
Equipment Needed
A yoga mat is optional, though a padded floor makes the repeated kneeling noticeably easier on the knees, and a willing partner is needed throughout.
Why It Matters
Carrying the slide all the way through to a flattened, pinned position asks for sustained control well past the moment the knee first crosses the hip. The front of the thigh (quadriceps, rectus femoris) drives the weight transfer into position, and the muscles along the sides of the abdomen (obliques) support the rotation. The lower back muscles (erector spinae) and the abdominal muscles running down the front of the stomach (rectus abdominis) brace the spine through the settle, and a hip muscle on the outer side of the pelvis (gluteus medius) stabilizes the base. The inner thigh muscles (adductors) help control the hips, and a muscle across the upper back and neck (trapezius) supports the pinning grip.
When to Do It
Knee Slice to Side Control works well within a grappling-focused session, added once the knee slice entry already feels familiar. Two to three sessions a week is a reasonable pace, as long as the partner on the other end is comfortable being passed repeatedly.
Anyone with a current knee or low-back issue should get individual guidance before adding this drill, since the kneeling transition and the sustained pressure both load those areas directly.
Getting Ready
Starting from a knee already across a partner’s hip, without settling into side control yet, checks the position this drill depends on. A few slow, partial settles preview the full transition before a complete rep against resistance is attempted.
Step-by-Step Instructions
- Cross the hip. Start with the knee already slid across the partner’s hip.
- Flatten the hips. Drive weight down to pin the partner’s hips flat to the mat.
- Pin the far side. Settle a grip and pressure on the far-side shoulder and hip.
- Hold side control. Establish a stable, fully settled position.
How Many, How Often
Knee Slice to Side Control is dosed by reps, with each full transition-and-settle sequence counting as one.
| Level | Where you’re at | What to do |
|---|---|---|
| Beginner | New to flattening the hips before settling | 3 sets of 3 to 4 reps per side |
| Intermediate | The flatten and the settle connect without stalling | 3 to 4 sets of 4 to 6 reps per side |
| Advanced | Comfortable establishing side control against active resistance | 4 sets of 6 to 8 reps per side |
Flattening the partner’s hips before settling matters more here than how quickly the transition finishes, since a pass that stops with the hips still turned leaves the position unsettled however far the knee has traveled.
Modifications and Variations
As an easier version, Guard Pass — Knee Slice practices the pin and the knee slide from inside the guard without the fight to flatten and hold side control against resistance. Knee Slide Only practices the slide alone.
Common Mistakes to Avoid
Settling before the hips flatten. Easing into side control while the partner’s hips are still turned leaves an easy angle for them to recover guard. The hips flatten fully before the settle is complete.
Neglecting the far-side pin. Focusing only on the near side while leaving the far shoulder and hip uncontrolled gives the partner room to shrimp away. Both sides are controlled for the position to hold.
Rising up out of the position. Lifting the hips or chest away from the partner once side control feels established gives up the pressure that keeps it secure. The pressure stays down through the whole hold.
After Your Set
A few slow hip circles release the hips after repeated transitions. Lying face down and pressing up onto the forearms for a few breaths eases the front of the hips and the low back after each settle.
Going Deeper
A flattened, pinned position is what stops a partner from recovering guard, more than getting the knee past the hip. Settling into a position that looks like side control but still leaves the hips turned is the usual problem. Checking that the hips are flat to the mat before calling the position settled fixes this faster than repeating a transition that keeps stopping one step short.
Someone new to this transition generally manages a slow, controlled settle against a cooperative partner within the first few sessions, then works toward establishing it against resistance over the following couple of weeks.
How to Know You’re Improving
- Hips that flatten fully to the mat before the settle finishes
- A far-side pin that gets the same attention as the near side
- Pressure that stays down through the whole hold
- A settle that holds up once the partner starts resisting
Flat hips under the pin matter more than how fast the transition happens.
Muscles Worked
- Rectus Femoris (a front thigh muscle that crosses both the hip and knee, carrying the weight through onto the passing side)
- Obliques (the muscles along the sides of the waist, turning the hips down to face their ribs)
- Erector Spinae (the muscles running along the length of the spine, holding posture as the position settles)
- Rectus Abdominis (the abdominal muscles running down the front of the stomach, keeping the chest low over their torso)
- Gluteus Medius (a smaller glute muscle at the side of the hip, holding the base wide once side control is reached)
- Adductors (the inner thigh muscles, squeezing in to stop them recovering guard)
- Trapezius (the broad muscle spanning the upper back and neck, holding the shoulder pin on the far side)
FAQ
Why does flattening the hips matter more than crossing the knee? A knee that crosses the hip without the hips ever flattening still leaves a turned, mobile target that can recover guard, while a pass that finishes with the hips flat removes that option.
Is this harder than isolating the knee slide alone? Yes, carrying the slide all the way through to a flattened, settled position against a resisting partner asks for more sustained control than practicing the slide alone.
Is some knee or hip fatigue after this drill normal? Yes, a worked feeling through the thighs and hips after a full set of transitions is expected. Knee pain that stays sharp past the session is worth a visit to a doctor or physical therapist.
Is this the same drill as the knee slice guard pass? Not quite. Guard Pass — Knee Slice practices the pin and the slide from inside the guard, while this version starts from a knee already crossed and concentrates on finishing the settle.
How often should the settle to side control be drilled? Two to three times a week, with a partner comfortable working from guard, suits most people building toward this skill.
