Neccessarily mean you will have a big punch or chin? Im asking esteemed members of this forum who know more than me.
No. Fighters lifting free weights, for the most part, is a fairly new phenomenon in the sport. Big muscles require more oxygen and slow you down.
can only talk from my experience. deadlift helps in substantial ways. strength is good for combat. nothing helps like technique and bag work for the punch. Deadlifts have a broad carry over. Just don't over do it. My two cents. don't fit the bill of esteemed or knowing more though.
Not for me like, punch power is half what your born with then technique you practice and drill over and over, rather what you learn. I always felt stiffer when doing weights and feel more powerful when I'm quick and loose. Similar with chin, your born with what your born with to a degree. Though the fitter you are your more likely to recover from a knockdown big shot etc. I'm neither an expert or esteemed though just my opinion!
I think it really depends on the fighter. I think heavy lifting can cost you some speed and fluidity, but if the gain in power offsets it then it may be worth it for that fighter. One example would be when marquez fought pacquiao awhile back. Rumor was Juan was squatting heavy in training and he knocked pacman out of the ring, I don't think heavy lifting helps your ability to take a punch at all. Just my humble opinions.
Punching power is genetic. The explosive force you develop from lifting weights can (to a certain extent, and making sure to mind your flexibility and conditioning) make you hit harder. But how hard you hit is mostly a tool you're born with or without. You have strong ass dudes like Primo Carnera who don't hit as hard as relative pencils like Max Baer
Oh and outside of a few theories link to neck strength which are egregiously untested and not backed up by boxing history at all, there's no way to improve your chin. At least punch power is something you can develop through technique and explosive force, just the final destination of your power is genetic Chin is pure birthright
With the o so sort after punching power just focus on the traditional exercises aswell as your technique, explosive movements most certainly will help also. (Try Edwin Haislets book "boxing" for technique) As for your chin if you haven't been boxing long your body isn't accustomed to it yet your chin will develop to an extent naturally, no amount of neck training will turn you into Jake Lammota but it most certainly does help! work your traps and neck like a mad man and reap the benefits. Squats and deadlift do help from my own personal experience from when I was a thin legged fellow moving up in weight a strong set of legs and a worthy core will certainly keep you anchored. If you care to message me I'd share more with you personally rather then writing a small book on the topic.
Some boxers have granite chins despite not doing neck exercises like George Foreman, Vitali Klitschko, Muhammad Ali and George Chuvalo. Some boxers have glass jaws despite doing neck exercises such as Anthony Joshua and Amir Khan All I was saying is that I'd like studies to prove the correlation.
George worked his neck so did Vitali I'm uncertain on Muhammad but you'd be naive to say his neck isn't strong! as for Amir he should focus more on his defense as should AJ a bombs a bomb! If it connects chances are most will be KO'd some will always have weaker chins BUT they can improve on what they have imagine if Khan and AJ didn't work their neck thats shudder inducing.
There is video proof of George using a head harness for his neck my man and I'm trying to remember Vitali doing neck exercises but now that I think about it, I believe he was just doing shrugs not using a head harness or bridges like a Tyson, Evander or a Dempsey. I'm 100% certain on George though my word on it.
