Muscle control: Lats Bounce

Rarity: Extremely Rare

Often demonstrated back at the golden era of bodybuilding, lats control is the once-famous, now-extinct muscle control of the biggest muscle group of the human body.

Expectedly, because of the size of the muscles involved, this control is best described as powerful and explosive, with bursting movements of the muscles during the performance.

Nowadays there aren't any casual performers of it.
