How can I rearrange the order of the workouts or exercises on my apple watch

Sorry, you cannot reorder the list of workouts. Your Apple Watch will present you with the list of the most common workouts you do and order them (probably) by how often you do them. There is no setting that would allow you to change the list or its order.

you can just keep your top workouts in that list (swipe left to delete ones you hardly use).

then you can go through the main list if wanting a different workout.

Exactly. Sometimes I wonder wth apple stakeholders are thinking when they have these ‘great ideas’. They need to hire UX people and get their heads out of their butts. There is potential for Apple to corner the market, but the only reason I still have one is because work pays for it. If I get a new job, I won’t be buying another apple product.

Apple's UI and UX team has all departed Apple since Steve Jobs's death; Apple Apps are just a mess. Why can't I put the 3 workouts I do to the top but need to scroll through tons of less-used workouts??? No common sense and user usability testing
