How to do Cat-Cow
Start on hands and knees, wrists under shoulders and knees under hips. On an inhale, drop your belly and lift your chest and tailbone (Cow). On an exhale, round your spine toward the ceiling and tuck your chin (Cat). Move slowly and let your breath set the pace rather than rushing the transition.
How the pacing works
Cat-Cow is a repeated movement rather than one long hold. This timer paces it as 8 reps, with a brief pause between each so you can settle into the next position rather than rushing. Because it's a symmetric, no-sides movement, the timer uses its Rest mode between reps instead of a switch-sides phase — press start and it counts every rep for you.
Common mistakes
Moving too fast and turning it into a bounce instead of a controlled stretch, holding the breath instead of syncing it with the movement, and only moving the upper back while the lower spine stays still.
Why it's worth doing
Cat-Cow moves the spine through both flexion and extension in a low-intensity, controlled way, which makes it one of the most commonly recommended movements for undoing morning stiffness or a long stretch of sitting. It's gentle enough to do daily without any warm-up first.
Variations
On hands and knees (shown above): the standard version, full range through the spine. Seated Cat-Cow: sit tall in a chair, hands on knees, arch and round the spine the same way — works at a desk when getting on the floor isn't practical. Child's Pose finish: after your last rep, sit your hips back to your heels and hold for a static stretch instead of continuing to move.
Who should be careful
Move within a comfortable range, especially at the extremes of the arch or round — this should never be painful. If you have a diagnosed disc issue, ask a physical therapist which direction is safe for your specific case before doing this daily.
FAQ
How many reps of Cat-Cow should I do? 8 slow reps, breathing with the movement, is a common recommendation, and it's exactly how this timer is paced.
What muscles does it target? The muscles along the spine and lower back, with light engagement of the abs on the rounding phase.
Is Cat-Cow good as a warm-up? Yes — it's one of the most commonly recommended gentle warm-up movements for the spine before other stretches or exercise, since it's low-intensity and moves the spine through both directions.
