Journalists riding to get exercise (5-2)
I believe the answer is:
press-up
'exercise' is the definition.
(press-up is a kind of exercise)
'journalists riding' is the subsidiary indication.
'journalists' becomes 'press'.
'riding' becomes 'up' (I've seen this in other clues).
'press'+'up'='pressup'
'to get' is the link.
(Other definitions for press-up that I've seen before include "Face-to-the-floor exercise" , "Form of arm exercise" , "Arm exercise while lying face down" , "Gymnastic floor exercise" , "PE exercise" .)
