'way of getting fit' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'name a nicest variety' is the wordplay.
'name' becomes 'calla' ().
'variety' indicates anagramming the letters.
'nicest' is an anagram of 'netics'.
'calla'+'netics'='CALLANETICS'
