Massaging sporty hip, yeah? (13)
I believe the answer is:
physiotherapy
'massaging sporty hip yeah?' is the definition.
I can't judge whether this definition defines the answer.
'massaging sporty hip yeah?' is the wordplay.
'massaging' indicates anagramming the letters ('massage' can mean to manipulate or distort).
'sporty'+'hip'+'yeah'='sportyhipyeah'
'sportyhipyeah' anagrammed gives 'PHYSIOTHERAPY'.
(Other definitions for physiotherapy that I've seen before include "Manipulative medical treatment" , "Treatment of illness or injury using massage, exercise etc" .)
