Knee Slide Only: A Complete Guide

Quick Intro

Knee Slide Only is a Martial Arts Drills exercise performed from all fours by isolating the knee slide across a partner’s hip that begins the knee slice guard pass, without completing the full transition to side control. Keeping the knee low and heavy for the whole slide is what this drill teaches.

Equipment Needed

No equipment is required, though the drill needs a partner able to work from guard safely.

Why It Matters

Keeping the knee low and heavy while sliding it across a partner’s hip asks for sustained control more than speed or strength. The front of the thigh (quadriceps, rectus femoris) drives the sliding knee, and the muscles along the sides of the abdomen (obliques) support the rotation into the slide. The inner thigh muscles (adductors) help control the hips through the movement, and a hip muscle on the outer side of the pelvis (gluteus medius) stabilizes the base leg.

When to Do It

Knee Slide Only fits well early in a grappling-focused session, before the full pass is added. Two to three sessions a week gives this slide enough repetition to turn into a habit, provided the partner is comfortable staying in guard for the drilling.

Anyone with a current knee issue should get individual guidance before adding this drill, since the kneeling slide places direct, repeated demand on the joint.

Getting Ready

Settling weight onto the near knee without sliding anywhere yet checks the base this drill depends on. A few slow, partial slides preview the full motion before a complete rep across the hip is attempted.

Step-by-Step Instructions

1. Settle the knee. Load weight onto the knee closest to the partner’s hip.
2. Stay low. Keep the knee in constant contact with the mat. The hips stay low as well, with the weight pressing down through the knee onto the hip.
3. Slide across. Move the knee across the partner’s hip in a continuous motion. The slide ends there, before any move toward side control.
4. Reset the base. Return the knee to the starting position and repeat.

How Many, How Often

Knee Slide Only is dosed by reps, with each full slide-and-reset counting as one.

Keeping the knee low and heavy through the whole slide matters more here than how quickly it crosses the hip, since a knee that lifts even briefly gives a partner the gap they need to recover guard once this slide becomes part of the full pass.

Modifications and Variations

As a harder version, Guard Pass — Knee Slice adds the cross-face grip and carries the sliding knee toward side control. Knee Slice to Side Control finishes the pass against resistance. The knee slide is the starting point for the pass, and a partner who stays still is the way to scale it down.

Common Mistakes to Avoid

Lifting the knee up and over the hip. Raising the knee off the mat is the habit this drill is meant to remove before the full pass is added. The knee travels low the whole way across.

Rushing the slide. Moving the knee quickly across the hip without staying heavy on it skips the control this drill is built to teach. A slower, deliberate slide builds the habit far more reliably than a fast one.

Losing contact with the hip mid-slide. Letting the knee drift away from the partner’s hip during the slide removes the pressure that makes the movement useful once resistance is added later. The knee stays connected to the hip throughout.

After Your Set

A few slow hip circles release the hips after repeated slides. Sitting back on the heels for a few breaths, then shifting the weight off the knees, eases the legs that drove each slide.

Going Deeper

A knee that learns to stay low and heavy here is what prevents a partner from recovering guard once the cross-face grip and the full transition are added. The knee tends to drift up off the mat partway through the slide, especially once speed is added. Slowing the slide back down and keeping the knee pinned fixes this faster than repeating a fast slide that keeps losing contact.

Someone new to this drill generally manages a slow, controlled slide within the first few sessions, then works toward sliding against light resistance from the partner over the following couple of weeks.

How to Know You’re Improving

1. A knee that stays low and heavy for the whole slide
2. A base that stays settled without wobbling through the motion
3. Contact with the partner’s hip that never breaks mid-slide
4. A slide that holds up against light resistance

A knee that stays on the mat matters more than how fast it crosses the hip.

Muscles Worked

• Rectus Femoris (one of the quadriceps at the front of the thigh, driving the sliding knee)
• Obliques (the muscles along the sides of the abdomen, supporting the rotation into the slide)
• Adductors (the inner thigh muscles, helping control the hips through the movement)
• Gluteus Medius (a hip muscle on the outer side of the pelvis, stabilizing the base leg)

FAQ

Why practice the knee slide before learning the full pass? Practicing the slide alone makes it much easier to build the habit of staying low and heavy, which is harder to notice and fix once the cross-face grip and the full transition are added at the same time.

Is this easier than the full Guard Pass — Knee Slice? Yes, the sliding motion alone leaves out the cross-face grip and the transition to side control.

Is some knee fatigue after this drill normal? Yes, a worked feeling through the thigh and hip after a full set of slides is expected. Knee pain that doesn’t ease off between sessions is worth a visit to a doctor or physical therapist.

When is the full pass added? Once the knee stays low and heavy through every slide without drifting, Guard Pass — Knee Slice adds the cross-face grip and the transition through to side control.

How often should the knee slide be drilled? Two to three times a week, with a partner comfortable working from guard, suits most people building toward this skill.
