People use work out for finding an answer or doing physical exercise.

The idea

In everyday neutral English, a noun object can go before or after out: work the cost out or work out the cost. A pronoun goes between: work it out. Exercise takes no object.

Examples

  • Maya worked out the answer on the train.
  • We worked the cost out before booking.
  • The clue was difficult, but Sam worked it out.
  • I work out at home before breakfast.
  • Their uncle works out twice a week.
  • Can you work out how much paint we need?

Watch out

Do not say work out it: put the pronoun before out. Context distinguishes solving from exercising.
