Crab Walk Hip Up

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 the glutes and hamstrings through the hip-up portion while the arms and shoulders support body weight and the core stabilizes 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.

Muscles Targeted

• Primary: Gluteus maximus, hamstrings
• Secondary: Rectus abdominis, obliques
• Tertiary: Triceps brachii, deltoids (arm support)

Starting Position

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.

Execution Steps

1. Lift your hips off the ground into the crab position, squeezing your glutes at the top
2. Shift your weight onto one hand and the opposite foot to prepare to step
3. Step the free hand and foot to the side, moving your whole body laterally while keeping your hips lifted
4. Bring the trailing hand and foot in to reset the crab position, hips still raised
5. Continue stepping sideways for the desired distance or number of steps
6. Lower your hips to the floor between sets, or pause periodically at the top for extra hip-up reps

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

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.

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

Tips for Progression

• 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

Training Notes

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.
