 This strike is a low roundhouse kick that hits the backside of the calf with the shin.While a Calf Kick sacrifices range in comparison to a standard low roundhouse kick to the thigh, the Calf Kick can't be checked with a knee or grabbed with an arm making it a safer kick for a striker in MMA matches vs opponents capable of checking low kicks or grapplers looking for takedown opportunities.The kick was popularized by former UFC Lightweight champion Benson Henderson during his tenure in the UFC.
