, right from the start, when Floyd is shadow-boxing, his coach is shouting: 'check hook, check hook, show how you check those punches"
Could anyone break down this for me?
Generally, I have noticed fighters practice hooks, uppercuts in a special way when shadow-boxing (examples are Broner, Jones, Ward), special because it looks somewhat different from when they are hitting mitts and such. Could anyone explain me that?
