Hip Bump to Kimura: A Complete Guide
Quick Intro
Hip Bump to Kimura is a Martial Arts Drills exercise performed by transitioning from the hip bump sweep off mount into a kimura shoulder lock on the trapped arm when the sweep is defended or stuffed, attacking the joint instead of continuing the roll. Keeping the trapped wrist and elbow controlled and rotating straight into the figure-four grip is what turns a stalled sweep into a submission attempt.
Equipment Needed
No equipment is required, though the drill needs a partner able to defend the sweep and the lock safely. The lock is applied slowly and released the instant the partner taps.
Why It Matters
Recognizing the moment the sweep stalls and moving cleanly into the lock asks for sustained attention and quick decisions together. The biceps (biceps brachii) drive the figure-four grip, and the muscles along the sides of the abdomen (obliques) and the abdominal muscles running down the front of the stomach (rectus abdominis) brace the trunk through the transition. The back of the shoulder (deltoid, posterior) supports the rotation into the lock, and a muscle across the upper back and neck (trapezius) maintains the grip. A muscle at the front of the hip (hip flexors, iliopsoas) helps anchor the hips, and the inner thigh muscles (adductors) support the base through the switch.
When to Do It
Hip Bump to Kimura works well within a grappling-focused session, added once the base hip bump sweep already feels familiar. Two to three sessions a week is a reasonable pace, always with a partner comfortable defending both the sweep and the lock.
Anyone with a current shoulder or elbow issue should get individual guidance before adding this drill, since the figure-four grip and the arm control both load those joints directly.
Getting Ready
Starting from the arm already trapped during a stuffed sweep attempt checks the control this transition depends on. A few slow, partial rotations into the figure-four preview the full lock before a complete rep against resistance is attempted.
Step-by-Step Instructions
- Recognize the stall. Feel the sweep get defended or stuffed by the partner.
- Keep the arm controlled. Maintain the trapped wrist and elbow without letting go.
- Rotate to the lock. Turn the body into position for a figure-four grip.
- Secure the kimura. Lock the grip and apply the shoulder lock slowly, stopping at the tap.
How Many, How Often
Hip Bump to Kimura is dosed by reps, with each full stall-to-lock transition counting as one.
| Level | Where you’re at | What to do |
|---|---|---|
| Beginner | New to keeping arm control through a stalled sweep | 3 sets of 2 to 3 reps per side |
| Intermediate | The transition and the lock connect under light resistance | 3 to 4 sets of 3 to 5 reps per side |
| Advanced | Comfortable completing the lock against active resistance | 4 sets of 5 to 7 reps per side |
Keeping the trapped arm controlled through the stall matters more here than how quickly the figure-four locks in, since letting go of the arm to reset gives up the submission attempt the moment the sweep stops working.
Modifications and Variations
As an easier version, Mount Escape — Hip Bump Sweep covers the trap and the sweep, without attacking the kimura when the sweep stalls. Slow Hip Bridge Drill practices the bridge alone.
Common Mistakes to Avoid
Releasing the arm when the sweep stalls. Letting go of the trapped wrist to reset and try the sweep again gives up the control this transition depends on. The arm stays controlled through the stall.
Rushing straight to the lock. Trying to force the figure-four before the body has rotated into position usually fails to secure the grip cleanly. The rotation happens first, with the lock following once the angle is right.
Forgetting the hips in the transition. Focusing on the arm and the grip while letting the hips drift loses the base under the transition. The hips stay engaged and anchored throughout the switch.
After Your Set
The hips benefit from a few slow circles once the set of transitions wraps up. A seated hamstring stretch, reaching gently toward the toes, eases the legs that supported each switch.
Going Deeper
A stuffed sweep does not have to mean losing the position when the trapped arm is already there to attack. Letting go of the arm the moment the sweep stalls is a habit carried over from resetting to try again. Practicing holding the arm through the stall, before adding the lock, fixes this faster than repeating transitions where the arm is released too early.
Someone new to this transition generally manages a slow, cooperative lock within the first few sessions, then works toward completing it against active resistance over the following couple of weeks.
How to Know You’re Improving
- An arm that stays controlled through the whole stall
- A rotation into the figure-four that happens before any forcing
- Hips that stay engaged and anchored through the switch
- A lock that is secured against a resisting partner and still applied slowly
Keeping hold of the arm when the sweep stalls matters more than how fast the lock closes.
Muscles Worked
- Biceps Brachii (the front of the upper arm, bending to lock the figure-four on their wrist)
- Obliques (the muscles along the sides of the waist, turning the hips to switch from sweep to lock)
- Rectus Abdominis (the abdominal muscles running down the front of the stomach, holding the trunk up as the attack changes)
- Posterior Deltoid (the back of the shoulder cap, pulling their elbow back to load the shoulder)
- Trapezius (the broad muscle spanning the upper back and neck, holding the grip as they fight to straighten the arm)
- Iliopsoas (the hip flexor group at the front of the hip, drawing the hips in to close the angle)
- Adductors (the inner thigh muscles, squeezing the knees to hold them in place)
FAQ
Why does holding the arm matter more than restarting the sweep? A partner’s arm that’s already trapped gives a second option the moment the sweep stalls, while releasing it to try the sweep again throws away control that may not come back as easily the second time.
Does this ask for more than the hip bump sweep? Yes, recognizing the stall and transitioning cleanly into a figure-four lock asks for quicker decision-making than committing fully to the sweep alone.
Is some shoulder or elbow fatigue after this drill normal? Yes, a worked feeling through the shoulder and the arm after a full set of transitions is expected. Elbow or shoulder pain that doesn’t ease off between sessions is worth a visit to a doctor or physical therapist.
Does the sweep come before this submission option? Yes, Mount Escape — Hip Bump Sweep builds the trap and the bridge this transition starts from, which is worth having solid before the kimura option is added.
How often should the hip bump to kimura be drilled? Two to three times a week, with a partner comfortable defending both the sweep and the lock, suits most people building toward this skill.
