Get physical with him. if you can't catch him ,and your completely out classed go to plan B mirror his style.. another words make him come in.. if he steps back , then you step back.. Get him out of his comfort zone, make him lead out. make him be first , then move in on his aggression . Remember to let your hands go when he comes in .. punch with him.. Don’t wait until he’s finished and gets back on defense. Catch him while he is on offense. Good luck
