I remember me first sparring session as a kid(about 11or12)and i was nervous and excited to actually put all my practise on show for my trainers and other boxers throughout the Gym.I forgot it was a sparring session in the third round and actually started really fighing my sparring panther.I hit him soo hard and unexpectedly that i knocked him against the ropes and rocked his head back soo sharply that he started choking on his own gumsheild.Eventually me trainer jump in to rescue him and i got a good telling off from my coach but he was also impressed by my power too.Me and me sparring panther made up afterwards though.I never got to spar with him again after that!
