Stroke stomach and top of leg (5)
I believe the answer is:
crawl
'stroke' is the definition.
(crawl is a kind of stroke)
'stomach and top of leg' is the wordplay.
'stomach' becomes 'craw' (craw is a kind of stomach).
'and' is a charade indicator (letters next to each other).
'top of' says to take the initial letters.
The first letter of 'leg' is 'l'.
'craw'+'l'='CRAWL'
(Other definitions for crawl that I've seen before include "Creep or move slowly" , "but very slowly on land" , "Proceed on hands and knees" , "progress slowly" , "Unusually slow rate of movement" .)
