Depends how physical it was.  I log heavy lifting at work occasionally as a weights session because. . .  Afterwards it feels like it.  It is all exercise after all. 

Well shit. My body hurt more today then when I exercise.

Then yeah log it.  But aim for a more intense exercise session next time. 

Just make sure you keep at it. It is a bit trickier to learn than squatting or deadlifting but you don't need to have perfect technique. I have taught the power clean to many people, including teaching it online, with much success. You need enough technique to be able to transfer optimal power to the barbell and avoid injury . Try to get feedback on your power cleans by other competent lifters or online by posting recorded videos.

Hope it offers useful information.
