The deep belly punch, also known as the "deep core punch" or "solar plexus punch," is a type of strike aimed at the abdominal region, specifically targeting the solar plexus and surrounding areas. This technique involves a precise and powerful blow, often thrown with a fist or a forearm, with the intention of causing discomfort, pain, or incapacitation. The deep belly punch has been employed in various martial arts disciplines, including boxing, kickboxing, Muay Thai, and mixed martial arts (MMA).
