Gym equipment? Cut and run without hesitation (9)
I believe the answer is:
exerciser
'gym equipment?' is the definition.
'exerciser' can be an answer for 'equipment?' (exerciser is a kind of equipment). I am unsure of the 'gym' bit.
'cut and run without hesitation' is the wordplay.
'cut' becomes 'excise' (I've seen this before).
'and' means one lot of letters go next to another.
'run' becomes 'r' (cricket abbreviation).
'without' indicates putting letters inside ('without' can be similar in meaning to 'outside').
'hesitation' becomes 'er' (sound made while hesitating - um, er).
'excise'+'r'='exciser'
'exciser' enclosing 'er' is 'EXERCISER'.
Can you help me to learn more?
(Other definitions for exerciser that I've seen before include "Device helping strengthen muscles" , "swimmer, perhaps" , "I work out" , "Fitness fanatic" , "One keeping fit" .)
