Times spent inside for physio exercises? (9)
I believe the answer is:
stretches
'exercises?' is the definition.
(stretch is a kind of exercise)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for stretches that I've seen before include "Lengthens" , "Reaches out" , "Extends limbs and muscles to their fullest" , "terms of imprisonment" , "Expands" .)
