Dali appears surreal in skilful training exercise (4,4)

I believe the answer is:

dead lift

'training exercise' is the definition.
(weightlifting exercise)

'dali appears surreal in skilful' is the wordplay.
'appears surreal' indicates anagramming the letters (the letters look different or surreal).
'in' is an insertion indicator.
'skilful' becomes 'deft' (deft means skilful).
'dali' anagrammed gives 'adli'.
'adli' inserted within 'deft' is 'DEAD-LIFT'.

I've seen this clue in The Guardian.
