The crab walk hip up is a bodyweight floor exercise performed in a reverse tabletop, or "crab," position that combines hip extension reps with lateral stepping. It builds theglutes and hamstringsthrough the hip-up portion while the arms and shoulders support body weight and thecorestabilizes the trunk against sagging. Unlike a standard glute bridge, the body is supported on both hands and feet and moves laterally between reps, which adds a hip stability and coordination demand on top of the glute work.
What Muscles Does the Crab Walk Hip Up Work?
- Primary: Gluteus maximus, hamstrings
- Secondary: Rectus abdominis, obliques
- Tertiary: Triceps brachii, deltoids (arm support)
How Do You Set Up for the Crab Walk Hip Up?
Sit on the floor with your knees bent and feet flat, about hip-width apart. Place your hands on the floor behind your hips with fingers pointing toward your feet. Press through your hands and feet to lift your hips until your torso is roughly parallel to the floor - this reverse tabletop is the crab position you will hold and move from throughout the exercise.
How Do You Perform the Crab Walk Hip Up?
- Lift your hips off the ground into the crab position, squeezing your glutes at the top
- Shift your weight onto one hand and the opposite foot to prepare to step
- Step the free hand and foot to the side, moving your whole body laterally while keeping your hips lifted
- Bring the trailing hand and foot in to reset the crab position, hips still raised
- Continue stepping sideways for the desired distance or number of steps
- Lower your hips to the floor between sets, or pause periodically at the top for extra hip-up reps
What Are the Key Form Cues?
- Keep your hips lifted throughout the walk - don't let them sag toward the floor between steps
- Squeeze your glutes hard at the top of each hip extension for maximum activation
- Brace your core to prevent excessive arching through the lower back
- Move deliberately - rushing the steps reduces control and glute tension
- Keep your head in a neutral position rather than craning your neck backward
What Are the Most Common Mistakes?
- Letting the hips drop during travel: reduces glute engagement and turns the movement into a plain crawl - keep the hips lifted the entire time.
- Overarching the lower back to gain height: shifts stress to the spine instead of the glutes - lift from the hips, not the low back.
- Taking steps that are too large or too fast: causes loss of hip height and stability - use smaller, controlled steps.
- Locking the elbows harshly on each step: increases wrist and elbow strain - keep a slight bend and land softly.
- Skipping the hip-up pause and only crawling: misses the concentrated glute contraction that gives the exercise its name - pause and squeeze periodically.
What Are the Best Crab Walk Hip Up Variations?
- Glute bridge: a stationary version that isolates hip extension without the walking component
- Single-leg hip bridge: increases unilateral glute and core demand
- Continuous crab walk: skips the top pause to emphasize movement over the isolated squeeze
- Weighted hip thrust: adds external load for greater glute overload once bodyweight reps are easy
- Bear crawl: a forward-facing quadruped crawl that shifts the emphasis to the anterior chain and shoulders
How Do You Progress the Crab Walk Hip Up?
- Increase the distance or duration of the crab walk before adding load
- Add a 1-2 second pause and squeeze at the top of each hip-up rep
- Progress to single-leg hip lifts within the crab position for added difficulty
- Slow the tempo of each step to increase time under tension in the glutes and core
How Should You Program the Crab Walk Hip Up?
Use the crab walk hip up as a glute and core activation drill early in lower-body sessions, or as a finisher, for 2-3 sets of 8-12 steps per side or 20-30 seconds of continuous movement. Rest 45-60 seconds between sets.
