Julius since he was five had been taught relentlessly how to box. It wasn't for serious fighting, just for exercise, but he enjoyed it and put his all into these workouts. 

Physically speaking, Wade was much, much stronger than he was, by virtue of age, however, Julius was not about to let him just shove him down like nothing. The smaller boy weaved under his hand, getting withing half an arms length. His mind was in slight disarray, so whatever was the best thing to do at that moment slipped Julius mind. He abandoned his body to instincts and muscle memory and as he ducked, he shoved his shoulder into Wade to try and throw him out of balance, then threw and right hand straight towards the older boys liver. Age gap or no, if this connected, there would be no doubt that Wade would be feeling this for hours.
