1982 Light Work

Sam didn't even let the opponents any time to digest his sudden outburst of attacks.

He leaped towards the nearest one with the dumbbell and slammed it on the side of his head. The young man fell to the ground and Sam mounted on him once again. He started swinging his dumbbell repeatedly.

Six hits. 

Three teeth, fractured nose and then a crack on the side of his eye socket.

A senior woke up from the daze and jumped at Sam to save his companion. But Sam threw the dumbbell at him making him dodge it. Sam jumped over and tackled him. He then rolled over and before anyone knew it, he held the guy in a choke with one hand. 

He picked up a weight with another hand and started beating the senior on the head and the chest.

Every hit broke a bone and the senior slowly lost himself in daze.
