The Crawl Switch is a dynamic rotational exercise that develops core stability, shoulder strength, and hip mobility by transitioning through a quadruped position. It challenges the obliques and serratus anterior while improving total-body coordination and functional strength.

Setup
- Start on all fours in a 'beast' position with hands directly under shoulders and knees under hips.
- Tuck your toes and lift your knees 1-2 inches off the floor, engaging your core and maintaining a flat back.
- Distribute your weight evenly between your palms and the balls of your feet.
How to do it
- Simultaneously lift your right hand and left foot off the ground while pivoting on your right foot.
- Rotate your torso to the right, threading your left leg underneath your body and extending it straight out.
- Exhale as you reach the peak of the rotation, keeping your supporting shoulder strong and chest open.
- Inhale as you reverse the movement to return to the starting beast position, then immediately repeat on the opposite side.
Form checklist
- Keep the supporting shoulder packed and stable, avoiding any shrugging toward the ear.
- Maintain a hovering knee position throughout the transition; do not let your hips touch the floor.
- Ensure the stationary foot pivots and stays flat on the ground during the rotation for balance.
- Keep your core braced to prevent your lower back from sagging during the switch.
Pro tips
- Drive hard through the palm of the floor-bound hand to create maximum space for your leg to slide through.
- Focus on 'opening the book' with your chest at the top of the movement to maximize oblique and pectoral engagement.
- Maintain a slow, controlled tempo to emphasize stability before increasing speed for metabolic conditioning.
Make it harder
- Add a 'hover' at the end of the extension, holding the leg off the floor for 2-3 seconds to increase time under tension.
- Perform the movement with a weighted vest to increase the load on the shoulders and core.
Frequently asked
- What muscles does the crawl switch work?
- The crawl switch primarily targets the deltoids, glutes, pectorals, and quadriceps, and also works the erector spinae, rhomboids, serratus anterior, and trapezius as secondary muscles.
- What equipment do you need for the crawl switch?
- The crawl switch requires no equipment — just your body weight.
- Is the crawl switch good for beginners?
- The crawl switch is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
