Cat-Cow
The cat-cow is a spinal mobility drill done on all fours, slowly alternating between rounding the back toward the ceiling and letting it sink with the chest forward, in time with the breath.

How it is executed
- Start on all fours with your hands under your shoulders and your knees under your hips.
- As you inhale, drop your belly toward the floor, lift your chest and tailbone, and look slightly forward to create the cow position.
- As you exhale, round your spine toward the ceiling, tuck your chin to your chest and draw your belly in for the cat position.
- Move slowly and smoothly between both positions, letting the motion flow with your breath to mobilize the entire spine.

Common mistakes
- Moving only the lower back. The upper back usually stays stiff and the whole range comes from the lumbar spine. Push the floor away with the hands as you round and open the chest as you sink, so the mid-back moves too.
- Going fast, as if it were a rep exercise. At speed, the vertebrae that move least get skipped and the drill loses its point. Spend two or three seconds in each position and move between them without hurry.
- Forcing the neck in each position. Throwing the head far back as you sink, or jamming the chin down as you round, concentrates the movement in the neck. The head follows the curve of the spine, without exaggerating either end.
- Losing the base of the hands and knees. If the elbows bend or the weight drifts back toward the heels, the spine is no longer horizontal and the range shortens. Hands under the shoulders, knees under the hips and arms firm.
Frequently asked questions
- What does the cat-cow work?
- More than strengthening, it mobilizes: it takes the whole spine, from the neck to the pelvis, through its range of flexion and extension without load. When rounding, the rectus abdominis draws the ribs toward the pelvis and the serratus anterior pushes the floor away to spread the shoulder blades; when sinking the back, the spinal erectors and multifidus extend segment by segment while the pelvis tilts forward. It is control and range work, not strength work.
- Which position is the cat and which is the cow?
- The cat is the rounded position: back arched toward the ceiling, chin to the chest and pelvis tucked. The cow is the sunken one: belly dropping toward the floor, chest forward and tailbone lifted. In Spanish the drill is often called cat-camel, and the camel can mean either the rounded hump or the sagging back depending on who explains it. What matters is that you reach both shapes fully, one after the other, and move slowly through the middle.
- How many reps of the cat-cow should you do, and when?
- Between 8 and 12 slow cycles, spending two or three seconds in each position, for 1 or 2 rounds. It is done without load and far from failure: the goal is for every vertebra to move, so quality rules over the count. It goes at the start of the session, before squats or deadlifts, or as a break after hours of sitting. If any position hurts, reduce the range; if the pain persists, stop and see a professional.
- How should you breathe during the cat-cow?
- Inhale as you sink the back and open the chest, and exhale as you round and draw the navel toward the spine. A long exhale helps empty the air so the abs complete the flexion; the inhale accompanies the extension and keeps you from forcing it. Let the breathing set the pace: each cycle lasts as long as one slow breath, with no rushing and no holding of the air.
