Starting off in what appears to be an octagon, the kickboxing ace attacks a pad with real venom.

After a long sequence punching and kicking the body-sized pad, the clip moves on to him in a boxing ring.

Getting things underway with equal vigour, Nasukawa quickly beings to tire and even hits the deck at one stage in exhaustion.

Throwing himself back to his feet, the Japanese fighter can barely muster up the energy to throw a punch or aim a kick as he meekly attacks the pad.
