Side Lying Lateral Costal Breathing

Side Lying Lateral Costal Breathing Exercise Description

Side Lying Lateral Costal Breathing is a positional breathing drill that teaches you to expand the upper-side rib cage while keeping a neutral spine and stacked ribcage-over-pelvis. The primary mover is the diaphragm, with the external intercostals assisting rib elevation during inhalation; the internal intercostals and abdominal wall contribute to controlled rib descent during exhalation. This exercise emphasizes three-dimensional thoracic expansion (especially lateral and posterior) and quiet, efficient breathing without neck or shoulder tension. The side-lying setup gives tactile feedback to target the lateral ribs and helps minimize lumbar extension or rib flare. Expect improved awareness of trunk alignment and coordinated breathing mechanics that support bracing and movement quality in many strength patterns.

How To Do The Side Lying Lateral Costal Breathing Exercise

‘- Lie on your side with head supported; hips and knees comfortably bent, feet stacked.
– Stack shoulders and hips; align ribs over pelvis; keep spine neutral.
– Place the top hand on your upper-side lateral ribs (mid-axillary line).
– Lightly reach the top arm forward to gently protract the scapula, opening rib space.
– Soften through the neck; keep shoulders down and relaxed.
– Inhale quietly through the nose, directing air into the top-side lateral and back ribs.
– Feel your hand lift outward and slightly posterior; avoid flaring the lower ribs.
– Allow the abdomen to expand naturally without force or belly pushing.
– Exhale through a soft, open mouth (or gentle pursed lips); feel ribs draw down/back.
– Let the abdominal wall gently firm on exhale while pelvis and spine stay steady.
– Keep the top knee lightly resting forward to prevent rolling; don’t arch the low back.
– Continue with smooth, unforced breaths, maintaining alignment and consistent lateral expansion.

Side Lying Lateral Costal Breathing Tips

‘- Support your head and keep hips and knees comfortably bent with feet stacked.
– Stack shoulders and hips, aligning ribs over pelvis while keeping a neutral spine.
– Place your top hand on the upper-side lateral ribs along the mid-axillary line for feedback.
– Lightly reach the top arm forward to gently protract the scapula and open rib space.
– Soften through the neck and keep the shoulders down and relaxed.
– Inhale quietly through your nose, directing air into the top-side lateral and back ribs.
– Feel your hand lift outward and slightly posterior on inhale while avoiding lower-rib flare.
– Allow the abdomen to expand naturally on inhale without forcing or pushing the belly.
– Exhale through a soft, open mouth or gentle pursed lips, feeling the ribs draw down and back.
– Let the abdominal wall gently firm on exhale while pelvis and spine stay steady.
– Keep the top knee lightly resting forward to prevent rolling and avoid arching the low back.
– Continue with smooth, unforced breaths, maintaining alignment and consistent lateral expansion.

Side Lying Lateral Costal Breathing Beginner Introduction

Side Lying Lateral Costal Breathing is a gentle, side-lying breathing drill that centers on expanding the ribs on the upper side of the body while the spine and pelvis stay well aligned. The breathing muscle and surrounding rib muscles guide the inhale, while the abs and rib muscles help the ribs ease back down on the exhale. Neck and shoulders stay relaxed so the effort feels grounded through the trunk rather than in the upper body.

The drill is performed lying on one side with the legs comfortably bent and the feet together, often with the upper hand resting along the side of the ribs to feel movement. As air flows in through the nose, the ribs on the top side widen and subtly fill toward the back, creating a three-directional sense of space around the chest. Breathing out through a soft mouth allows the ribs to settle and the abdominal area to gently engage while the lower back and pelvis remain steady. Over time, this builds awareness of rib movement, core support, and smooth, efficient breathing that carries over into many strength and daily movement patterns.
