Way to get fellow good and muscly (6)
I believe the answer is:
strong
'muscly' is the definition.
(I've seen this in another clue)
'way to get fellow good' is the wordplay.
'way to get' becomes 'st' (I've seen this in other clues).
'fellow' becomes 'ron' (masculine given name).
'good' becomes 'g' (abbreviation).
'st'+'ron'+'g'='STRONG'
'and' acts as a link.
(Other definitions for strong that I've seen before include "Not faint or feeble" , "strong" , "curator" , "muscular or concentrated" , "Powerful; full-flavoured" .)
