How is this different from a crunch?

A crunch targets the superficial rectus abdominis through spinal flexion, while the draw-in targets the deeper transverse abdominis to stabilize the spine.

Can I perform this exercise standing up?

Yes, once you master the technique lying down, you can perform it while sitting, standing, or even during other compound lifts to improve stability.

How often should I practice the abdominal draw-in?

Since it is a low-intensity activation exercise, you can perform it daily or as part of your warm-up routine before heavy lifting.

Learn how to perform the abdominal draw-in maneuver to strengthen your transverse abdominis and improve spinal stability with our expert guide.

How to Perform

Lie on your back on a flat surface with your knees bent and feet flat on the floor.
Place your hands on your lower abdomen just inside your hip bones to feel the muscle contraction.
Take a deep breath in and as you exhale, gently pull your belly button toward your spine without moving your hips.
Maintain a neutral spine throughout the movement ensuring your lower back does not flatten or arch excessively.
Hold the contraction for ten seconds while continuing to breathe normally in shallow breaths.
Slowly release the tension and repeat the process for the prescribed number of repetitions.

Common Mistakes

Holding your breath during the contraction
Pushing the stomach outward instead of pulling it in
Tilting the pelvis and flattening the lower back against the floor
Tensing the chest and shoulders instead of isolating the core
