That is the going theory. Of course, going theories come...and go. When I was a kid, milk was good for you, essential part of a balanced diet. Then it was bad, and classed as junk food. Then good again. :conf
From what I've witnessed, puncher's are born not made. I've seen a lot of guys who have incredible lifts, but for whatever reason, can't punch hard at all. In contrast, I've seen guys that don't even lift weights that are among the hardest punchers in the gym. There is also a different type of power as well. There is POP and there is the Thud. A guy like Pacquaio has the POP and a guy like Canelo has the Thud. Personally, I prefer the POP more than the Thud. POP will break your bone and knock you clean out. A thud is almost like a push. At the higher levels, a guy like Wilder has the POP. David Haye had the POP. That POP is what knocks a mother ****er out. I know a lot of people don't want to hear this, but it is what it is. A puncher is born, much in the same way a guy's ability to take a beating is innate.
Look at Marquez. I thought he looked very stiff against both Bradley and Alvarado. Plus, he now has a knee issues that didn't exist before, forcing him to retire from the sport.
Obviously when all things are eqaul the stronger fighter will win. So it can only help to become stronger.
What you are talking about there is largely a function of proper technique. When you get your weight turned in front of your hands, you get a whip-lash effect and concussive force. When your weight is behind your hands, then you are pushing your punches, no matter how hard you push. Most guys fall some place in between.
Wool suds are too hard for me. Can you recommend anything that can be done with just bodyweight? Preferably while lying on the couch watching TV?
Pushing and throwing a punch, that's just technique. David Haye is an avid weightlifter btw. Saying a puncher is born is just stupid, the only relevant part of that is your muscle attachments and lever lengths. There are numerous variables you can work on and improve. Technique, strength and power are the main things when it comes to delivering a hard punch, and they can be greatly improved through training.
that's why I get mad at some of these guys who claim to be experts on this and to know everything and try to denigrate other's for their opinions or statements on sports science and nutrition. The science on this **** is constantly changing and contradicts itself often.
