The Slideboard Bodysaw is the elite evolution of the plank, designed to force maximal anti-extension tension and bulletproof your midsection.
Look, if you’re still doing two-minute static planks and wondering why your core feels like a wet noodle during a heavy squat, you’re wasting your biological potential. This is the 2026 blueprint for high-status abdominal recruitment. We are moving the lever arm to challenge your “pillar” stability in real-time.

Slideboard Bodysaw: The Anti-Extension Powerhouse
The Slideboard Bodysaw is a core stability movement that involves sliding your body backward and forward while maintaining a perfect plank position. Unlike the Ab Wheel Rollout, which moves the arms away from the body, the bodysaw moves the entire “chassis” away from the elbows. This creates a massive demand on the rectus abdominis and obliques to prevent the lower back from arching.
- Primary Focus: Abs, Obliques, Serratus Anterior, Lats.
- Equipment Needed: Slideboard (or furniture sliders/towels on a slick floor).
- Skill Level: Intermediate. Requires foundational “hollow body” strength.
- Key Purpose: Build elite anti-extension strength and improve breathing under tension.
Slideboard Bodysaw execution. Focus on the rock-solid spine and controlled glide.
Why the Bodysaw Dominates the Standard Plank
The standard plank is static; the Bodysaw is dynamic. By shifting your weight, you are constantly changing the lever length and torque on your spine. This is the ultimate “transfer” exercise for heavy compound movements like the Barbell Deadlift.
- Shredded Aesthetics: High-tension “pulses” in the core drive muscle density and vascularity.
- Serratus Activation: The sawing motion targets the serratus anterior (the “boxer’s muscle”), framing your abs for a superior look.
- Diaphragmatic Control: To succeed, you must master the brace. Use 90/90 Wall Balloon-Breathing to prime your internal pressure before your set.
- Shoulder Stability: It builds a “quiet” shoulder girdle that can handle high loads in the Barbell Overhead Shrug.
Step-by-Step Form: The 5-Point Checklist
- Setup: Forearms on the floor, feet on the slideboard or sliders. Start in a perfect plank. If you can’t hold this, regress to the Ab Wheel Iso.
- The Brace: Squeeze your glutes and tuck your ribs toward your pelvis. Your spine should be a straight line from ears to ankles.
- The Saw: Slowly push your body backward by extending at the shoulders. Go as far as you can without your hips sagging.
- The Pull: Use your core and lats to pull yourself back to the starting position. Think about “crunching” your ribs to your hips.
- The Breathing: Short, sharp “bracing” breaths. Do not hold your breath until your face turns purple.
“The Slideboard Bodysaw is about eccentric control of the lumbar spine. If you lose your ‘hollow’ position, the exercise becomes a lower-back wrecker. We use this to bridge the gap between basic core drills and the massive demands of the Barbell Front Squat Iso. Control the glide, own the spine.”

3 Common Mistakes & How to Fix Them
Sloppy reps on a slideboard are a waste of biological data. Dial it in.
1. The “Banana Back”
The Mistake: Hips sagging toward the floor as you slide back. The Fix: Reduce your range of motion. Only go as far as you can stay “hollow.” Squeeze your glutes harder than you think possible.
2. Piking the Hips
The Mistake: Pushing your butt into the air to make the move easier. The Fix: Keep your body parallel to the floor. If you need a break, the set is over.
3. Shoulder Shrugging
The Mistake: Jamming your shoulders into your ears. The Fix: Depress your scapula. Think about “pulling your shoulders away from your ears” to engage your lats and serratus.
“From a metabolic and performance perspective, core integrity is the bottleneck for total body power. If you can’t stabilize your midsection, you can’t transfer energy from your legs to your upper body. Think of the Bodysaw as ‘stiffening’ the biological links in your chain. It’s the foundation for elite athleticism.”

Programming & Integration
The Bodysaw is a high-intensity core movement. Don’t bury it at the end of a 2-hour workout when you’re already fried.
- Core Primary: 3 sets of 8-12 slow, controlled reps. 60s rest.
- The Stabilizer Superset: Pair with Walking Farmer’s Carries for a total-body “stiffness” workout.
- Performance Primer: 2 sets of 5 reps before heavy squats to “wake up” the anterior chain.
Variations to Scale Difficulty
- To Regress: Use the Stability Ball Rollout to decrease the lever demand.
- To Progress: Move to the Single-Leg Slideboard Bodysaw to introduce an anti-rotational challenge.
- The Absurd: Add a weighted vest or have a partner place a plate on your back—but only if your form is flawless.
The Verdict
The Slideboard Bodysaw is the ultimate diagnostic for your core. It builds the stability, aesthetic density, and performance-ready “stiffness” that standard planks simply cannot touch. Master the glide, lock the ribs, and grow.
Slideboard Bodysaw FAQ
What if I don’t have a slideboard?
Use furniture sliders on carpet or a towel on a hardwood/laminate floor. The “pixels” of the surface don’t matter as much as the quality of the friction.
Is this better than the Ab Wheel?
They are “cousins.” The Ab Wheel is usually more intense on the lats, while the Bodysaw is more demanding on the lower abs and pelvic stability. Use both.
Should I do these if I have lower back pain?
Only if your PT clears you. Done correctly, it fixes back pain by strengthening the abs, but done poorly, it causes it. Keep that spine neutral.
