Do you use your Apple Watch for fitness?

I'm afraid you are mistaken, the watch relies on your arm free swinging.

You can try to calibrate it using a walk and run workout to improve accuracy but it will not accurately count steps if your arm is not moving.

The iPhone also counts steps and is used in conjunction with the watch if both are on you.

That's one of the metrics it uses (arm swing), but it can get data from other sources too. Accelerometer, GPS etc. I know it's worked for me when using a shopping cart. I didn't check for actual accuracy, but it did record steps. Would it be 100% accurate? Of course not. But in my experience, when I've specifically checked, it has recorded steps while using the cart, with my wrist that has my watch on the cart, not swinging by my side. I'm right handed and wear my watch on my right arm, so I'd actually expect to get poorer results than most.

I should check again though and see if those were steps recorded by the iPhone and not the Watch. I'm 95% sure it was the Watch, but not 100%. But again, it does use metrics other than arm swing.

I'd expect the watch to have notably fewer steps counted in a scenario like this while the iphone may make up for it. Definitely review your steps' data source.

I can tell you when i'm pushing a grocery cart or my baby's stroller it absolutely counts less steps and if I'm playing a piano or drums or shaking a jar to make baby formula it inflates my steps.

It learns your behavior/movements over time (and since its on your wrist arm movements are notable factor as compared to how the iphone tracks steps), using workouts to further calibrate it in various walk/run scenarios can help but unusual changes in movements when pushing a cart such as your arm not swinging like it normally would will absolutely cause a change in accuracy.

I suppose you could try calibrating it by performing an indoor walk workout while pushing a cart but that may distort the accuracy of your everyday walking.
