Does some strokes

SWIMS

Might involve moving through water with rhythmic arm and leg motions.

"Does some strokes" is a playful clue where "strokes" hints at swimming motions. In swimming, each movement through the water is called a stroke, so someone who "does some strokes" is swimming. The answer "SWIMS" fits because it directly describes the action of performing those strokes. The clue cleverly avoids saying "swimming" outright, relying on the double meaning of "strokes" to lead you there.
