口诀：Some exercises are countable, some are not.
Countable exercises are specific and can be counted, like push-ups or sit-ups.
Uncountable exercises are general and cannot be counted, like yoga or cardio.
Remember, countable exercises have an "s" at the end, while uncountable exercises do not.
So, when talking about exercise, choose the right form to express your thoughts.
Countable or uncountable, it's important to know, for clear communication wherever you go.
