Spider Crawls Overview
The spider crawls move is a core and plank drill. It works your abs, the muscles across your belly. It also uses your shoulders and your hip flexors. You start in a high plank. Then you bring one knee toward the same elbow. You switch sides and keep going. You need no equipment. The spider crawls move builds a strong, stable core. It also works your balance and control. Holding the plank while you move is hard. This makes it great for core strength. It is good for lifters who want a tougher plank. Use it in your core block or warm-up. Keep your hips level and your core tight. Move slow and controlled the whole time.
What Is The Point of the Spider Crawls?
The spider crawls exercise builds core strength while improving hip mobility. It fires up your abs and teaches your body to move as one unit.
How To Do The Spider Crawls
- Start in a strong high plank position with your hands stacked under your shoulders and your body in one straight line from head to heels. Set your shoulders down and brace your core hard before you move.
- Squeeze your glutes and pull your ribs down so your hips do not sag or pike. This is a moving plank, so holding that rigid line is the whole challenge.
- Take a breath and slowly bring your right knee up and outward toward your right elbow, staying low and controlled. Keep your hips level and resist the urge to twist.
- Draw the knee toward the outside of your arm without lifting your hips up. The lower you keep your hips, the more your abs and hip flexors have to work.
- Pause for a beat with the knee near the elbow and keep your core tight. Do not let your back round or your shoulders collapse.
- Return your right foot to the plank position under full control, keeping your body flat and stable the whole time. Do not rush it back.
- Repeat with your left knee traveling toward your left elbow, keeping your hips low and level as you switch sides.
- Continue alternating sides for your target reps, keeping your plank rock solid throughout. Because it demands control, aim for 8 to 12 slow reps per side or a set time under tension.
Spider Crawls Form Tips
- Keep your body in a straight line. Head to heels.
- Keep your hips level the whole time. Do not let them lift.
- Put your hands under your shoulders. This holds you steady.
- Bring your knee to the same-side elbow. Move slow.
- Keep your core tight the whole time. This is the main work.
- Move one leg at a time with control. No fast kicking.
- Breathe steady. Do not hold your breath.
- Keep your shoulders strong and steady. Do not sag.
- Keep your neck in line with your back. Do not drop your head.
Common Mistakes to Avoid for the Spider Crawls
- Letting the hips sag toward the floor. A sagging plank dumps the load onto your lower back and takes your abs out of the movement. Squeeze your glutes and brace your core so your body holds one straight line as your leg moves.
- Piking the hips up. Lifting your hips high to make the knee drive easier turns the movement into a cheat and removes the core challenge. Keep your hips low and level so your abs stay under real tension.
- Rushing the reps. Speeding through the crawl uses momentum and lets your form fall apart. Move each leg slowly and deliberately so your core controls the whole motion.
- Letting the shoulders drift behind the hands. When your hands are no longer under your shoulders, you strain the joint and lose stability. Keep your hands stacked directly under your shoulders throughout.
- Twisting the torso as the knee comes up. Rotating your trunk to reach the elbow bleeds tension off the target and stresses your spine. Keep your hips and shoulders square and let only the leg move.
- Holding your breath the whole set. Freezing your breath makes bracing inconsistent and tires you out fast. Breathe steadily so you can keep a firm brace from rep to rep.
- Rounding the upper back. Hunching your shoulders collapses your plank and weakens your base. Push the floor away and keep a long, flat spine from head to heels.
- Only bringing the knee halfway. Cutting the range short reduces the hip and ab work the drill is meant to deliver. Drive the knee up toward the outside of your elbow on each rep.
- Letting the head drop or crane up. Dropping or lifting your head throws off your spinal line and can strain your neck. Keep your neck neutral with your gaze just ahead of your hands.
- Moving both legs too fast to feel the abs. Blasting through reps trains speed, not core control. Slow down and genuinely feel your abs and hip flexors working each rep.
- Letting one side work harder than the other. Favoring your stronger side over many reps builds an imbalance. Match the effort and range on both sides as you alternate.
Spider Crawls Workout Tips
- Treat this as a moving plank. The entire benefit comes from holding a rigid, braced body while your legs travel, so keep that plank solid the whole time.
- Keep your hips low and level throughout. A low, flat position keeps your abs and hip flexors under tension instead of letting them off the hook.
- Move slowly and deliberately. Controlled reps build real core stability, while a fast crawl just uses momentum.
- Squeeze your glutes to lock your torso. A tight backside helps hold the straight line and stops your hips from sagging.
- Keep your hands stacked under your shoulders. That position protects the joint and gives you a strong, stable base to crawl from.
- Drive the knee toward the outside of the elbow. Aiming wide opens up the hip and increases the work for your abs and hip flexors.
- Use it as a warm-up or in a core circuit. It builds shoulder stability, core control, and hip mobility all at once, which primes you for bigger lifts.
- Keep your hips and shoulders square. Resisting the twist trains true anti-rotation strength and protects your spine.
- Breathe steadily and keep your brace firm. Consistent breathing lets you hold tension across the whole set.
- Progress by slowing the tempo or adding a pause. Holding the knee near the elbow for a beat raises the challenge without any equipment.
- Match your effort on both sides. Alternating fairly keeps you from building a left-to-right imbalance over time.
- Keep your neck neutral with your gaze just ahead. A long spine from head to heels keeps your plank strong and your neck safe.
- Film yourself from the side. Video quickly shows whether your hips are sagging or piking during the crawl.
- Add a resistance band around your thighs to progress. The band forces your hips to work harder to stay level and square.
- Pair spider crawls with a static plank or dead bug. Combining moving and still core work builds complete midsection strength.
- Stay consistent a few times a week. Core control improves with regular, quality practice, so keep these in your routine.
