Determined to destroy tenor pair in musical exercise (5,5)
I believe the answer is:
bench press
'exercise' is the definition.
(bench press is a kind of exercise)
'determined to destroy tenor pair in musical' is the wordplay.
I cannot really understand how this works, but
'pair' could be 'pr' (abbreviation) and 'pr' is located in the answer.
'musical' could be 'chess' (Benny Andersson and Bjrn Ulvaeus musical) and 'chess' is located in the remaining letters.
The remaining letters 'ben' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for bench press that I've seen before include "Show of strength" , "Weighty exercise" , "lift" .)
