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

'pt hayes regularly dipped into loaded pickle jars' is the definition.
I can't tell whether this defines the answer.

'hayes regularly dipped into loaded pickle jars' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'dipped into' means one lot of letters goes inside another.
'loaded' indicates an anagram (loaded can mean drunk).
The alternating letters of 'hayes' are 'hys'.
'pickle'+'jars'='picklejars'
'picklejars' is an anagram of 'picaljerks'.
'hys' inserted within 'picaljerks' is 'PHYSICAL JERKS'.

Can you help me to learn more?

(Other definitions for physical jerks that I've seen before include "Training" , "part of fitness programme" , "Energetic exercises" .)
