morning jerks

[englishhobby]

Does the sentence below sound all right to a native speaker of English?

Every morning all the year round I do my morning jerks to dancing music.

Is the phrase "morning jerks" instead of exercises widely used by native speakers? Which is more common?

I came across this sentence in a worksheet I had been given by a senior teacher to teach vocabulary related to sport to my students. There is one more meaning of "jerk" - a dull guy, is it correct to use "jerks" when talking about morning exercises as physical activity one does to keep fit?

'Morning jerks' is not commonly heard.

'Physical jerks' was once common but now sounds old-fashioned.

You're more likely to hear morning workout these days.

When I saw "morning jerks" I thought it was one of those radio shows.
