can you explain the different meaning of "exercise"?
exercise is equal to sport?
do exercise or do exercises? what's the difference?
exercises and its phonetic transcript?
is it "eksosaiziz"?
Exercise doesn't have to be sport- I can go for a walk to get some exercise, but I wouldn't call it sport. In the singular, we are thinking about physical activity, but in the plural, we are thinking about different specific types of exercise, as in a gymnastic routine. Your transcriptions fine- stress the third syllable.
