Exercise, or call the lift? (5-2)

I believe the answer is:

press-up

I'm a little stuck... Click here to teach me more about this clue!

'exercise' is the definition.
(I know that press-up is a type of arm exercise)

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for press-up that I've seen before include "Arm exercise while lying face down" , "Gymnastic floor exercise" , "Keep-fit exercise" , "PE exercise" , "Face-to-the-floor exercise" .)

I've seen this clue in The Times.
