Cat Stretch
Also works: Middle Back · Traps
On hands and knees, you round the spine one segment at a time — tailbone tucking, ribs lifting, head dropping last. It is a mobility drill rather than a hold, and its value is teaching your spine to move in small pieces instead of hinging at one sore vertebra.
Own the movement
Set up first, then execute. Every cue below is something you can check on your next set.
Before the first rep
- Set hands directly under the shoulders and knees directly under the hips, shins parallel.
- Spread your fingers and push the floor away so your shoulder blades sit flat on the ribcage rather than pinched together.
- Start from a genuinely neutral spine — flat lower back, head in line — not from an already-arched sag.
- Put a folded towel under the knees if the floor is hard; discomfort at the kneecap ends the drill early.
Every rep
Breathing & tempo — Exhale fully as you round — the exhale is what lets the ribcage close and the mid-back move — and inhale as you return to neutral. Roughly one breath per rep, three to five seconds each way.
How much, how often
Where to start, and what to change when it stops being hard.
Bodyweight only, and no attempt to hold end range for long. Eight to ten slow rounds of three to five seconds each, once or twice a day. Progress by moving more smoothly through the stiff segments, not by rounding harder.
What goes wrong
The errors that show up most often, and the cue that fixes each one.
Slow the whole thing to five seconds and start at the tailbone every time. Film it from the side once — you are looking for an even curve, not a peak with two flat sections either side.
Keep your gaze on the floor between your hands until the ribs have already lifted, then let the head follow. Neck first means the spine below barely moves.
Do eight slow ones instead. The point is to find the segments that will not move, and you cannot feel them at speed.
Keep the arms straight and actively press the floor away throughout, so the movement stays in the spine and does not turn into a shoulder collapse.
Why bother
Most stiff backs are not uniformly stiff. Two or three segments do all the bending while the rest sit locked, which is exactly why one spot gets sore. Rounding slowly and deliberately from tail to skull asks every segment for a small contribution and makes the locked ones obvious.
Being on all fours takes your spine out of gravity's line, so the erectors do not have to hold you up while you try to move. That is the difference between this and a standing forward fold: here you can move the spine without also loading it.
Where it fits
In a warm-up before deadlifting or squatting, in a desk break, or as a between-set filler. Eight to ten slow rounds takes under a minute. Pair it with its opposite — arching to a neutral or extended position — rather than only ever rounding.
If this one isn't it
No kit, too hard, or too easy — here's where to go instead.

Asked and answered
Is rounding my back safe if I have been told never to round it under load?
Yes, and the two are not in conflict. The advice against rounding applies to a loaded spine — a barbell on your back or in your hands. Unloaded, on all fours, spinal flexion is normal movement your spine is built for. Avoiding it entirely is how backs get stiff in the first place.
Should I do this before deadlifting?
A few slow rounds, yes — it wakes up segmental control without fatiguing anything. Do not do a long session of end-range flexion right before heavy pulling, though. Round for mobility, then do a couple of hip hinges to remind yourself what neutral feels like before you load the bar.
What about the arched half people call cow?
Do both. Only ever rounding trains half the range. Alternate: round on the exhale, then return through neutral to a gentle arch on the inhale, letting the movement come from the mid-back rather than dumping it all into the lower back.
