Young male left in exercise venue largely in a thrilled way (6)

I believe the answer is:

gladly

I'm a little stuck... Click here to teach me more about this clue!

'venue largely in a thrilled way' is the definition.
I can't judge whether this definition defines the answer.

'young male left in exercise' is the wordplay.
'young male' becomes 'lad' (I've seen this in another clue).
'left' becomes 'l' (common abbreviation).
'in' indicates putting letters inside.
'exercise' becomes 'gy' (I am not sure about this - if you are sure you should believe this answer much more).
'lad'+'l'='ladl'
'ladl' placed inside 'gy' is 'GLADLY'.

Can you help me to learn more?

(Other definitions for gladly that I've seen before include "Delightedly" , "With pleasure" .)
