It really sounds like "do you like to motion", which is veery funny. I can only imagine some awkward guy dressed in yoga pants and a slim shirt trying to "motion". Don't ask why!
If I understand it correclty, "en øvelse" would mean an exercise in a text book or practice for a sport or instrument. "At motionere" is a verb meaning TO exercise, such as in a gym (et motionscenter).
Motionere is "exercise", just for the sake of getting some movement in your bones. Øve is "practice", with some higher goal behind it.
