Diddy Arrest Sparks New Workout Craze

This is adding insult to alleged felony -- Diddy’s kettlebell arrest is now being mocked by workout fiends ... who are using his alleged weapon of choice to get in shape and get laughs.

The day after he got arrested ... “The Diddy Workout” instantly became a thing for gym rats ... who've taken to grabbing kettlebells, doing a few reps and belting out Diddy's catchphrase ... “take that, take that.” It's as ridiculous looking as it sounds.

Based on social media, trainers are picking up on the craze ... adding the "Workout" to classes.

So, Diddy's bust is a silver lining for muscle heads. Still totally sucks for Diddy.
