'be on the up again' is the definition.
(resurgent means surging or on the up again)

'after short break pressing' is the wordplay.
'after short break' becomes 'res' (I can't explain this - if you can you should believe this answer much more).
'pressing' becomes 'urgent' (synonyms).
'res'+'urgent'='RESURGENT'

'to' is the link.
