'reminders' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'review of chest enhancement a to g' is the wordplay.
'review of chest enhancement' becomes 'postit' (I am not sure about this - if you are sure you should believe this answer much more).
'a to g' becomes 'notes' (I've seen this in another clue).
'postit'+'notes'='POST-IT NOTES'

'provides' is the link.
