It obviously worked... He also waited for Louis to come into the gym and waited with a brick in each hand and ran at Joe and threw a punch with the brick in his hand Louis moved away and then Blackburn said see once an opponent moves away from one hand you still have another hand to wack them with
Buddy McGirt, would have a stop watch with him while watching his guys spar if his guy did something wrong, he would stop the round and start the round over, sometimes having 20 minute rds, he did this with Lamon Brewster and Arturo Gatti. For the second Gatti - Ward fight, he wanted Gatti to box and not get into trading punches. When Gatti reverted to his old style of brawling, McGirt would stop the round and start the round all over again.
Practise straight punches alongside a wall, your elbows aren't allowed to touch the wall. When boxing (bag, shadow, etc) pretend you're on the phone with your girlfriend, she gets pissed if you don't listen. One hand should always be "on the phone". If the left hand punches the right hand holds the phone, and vice versa.
