The Abdominal 4 points is a bodyweight core-bracing exercise performed in a four-point (quadruped) position on your hands and knees. It trains the abdominals and deep core stabilizers — the rectus abdominis and the muscles that brace your spine — by teaching you to hold a stable, neutral trunk while you control your breathing and resist movement. It is a beginner-friendly drill that builds the anti-extension and anti-rotation strength that carries over to bigger lifts.
How to do the Abdominal 4 points
- 1Set up on the floor on all fours, placing your hands directly under your shoulders and your knees directly under your hips, with shins and toes resting on the floor.
- 2Spread your fingers and press the floor away to set your shoulder blades, keeping your arms straight but not locked.
- 3Set your spine in neutral — a flat back from head to tailbone, with your neck long and your gaze toward the floor just ahead of your hands.
- 4Brace your abdominals as if bracing for a light punch, and gently draw your belly button up toward your spine without rounding your back.
- 5Hold this braced four-point position with steady, controlled breathing, keeping your hips level and your weight evenly spread across both hands and both knees.
- 6Maintain the brace for the prescribed time or reps, resisting any sag or twist in your trunk.
- 7Release the brace under control, lower your hips back to a rest position, and reset before the next repetition.
Form tips
- Keep a neutral spine throughout — avoid arching or rounding by imagining a long straight line from the crown of your head to your tailbone.
- Breathe continuously into the brace rather than holding your breath, so the abdominals stay engaged the whole set.
- Stack your joints: hands under shoulders, knees under hips, so the brace works the core instead of fatiguing your wrists or shoulders.
- Keep your hips square and level to the floor so both sides of your core share the work evenly.
Common mistakes
- Letting the lower back sag toward the floor, which shifts load onto the spine and takes tension off the abdominals.
- Rounding the upper back up toward the ceiling, which loses the neutral position the drill is meant to train.
- Holding your breath to feel tighter, which raises pressure and makes the brace impossible to sustain.
- Letting the hips tip or rotate to one side, which lets the stronger side take over and reduces the core challenge.
Frequently asked questions
What muscles does the Abdominal 4 points work?
It targets the core — the rectus abdominis and the deep abdominal stabilizers that brace the spine. Because it is done on hands and knees, it trains these muscles to hold a stable trunk rather than to crunch.
Is the Abdominal 4 points good for beginners?
Yes. It uses only your body weight and a stable four-point position, so it is one of the safest ways to learn core bracing and a neutral spine before progressing to harder anti-extension work.
How long should I hold each rep?
Start with 3–4 sets of a 15–30 second braced hold, or 8–12 slow reps if you release and reset each time. Stop the set once you can no longer keep a flat back.
What is a good progression from the Abdominal 4 points?
Once you can hold a stable brace, progress by lifting one arm or the opposite leg to add an anti-rotation demand, or move on to a full plank to raise the anti-extension challenge.
