Exactly.
To me, you’re pushing to two totally different planes. With a squat, you’re pushing towards the ceiling, with a punch, you’re whipping to your front. While weight itself is going to make you punch harder, the strength in your legs doesn’t matter for shit - if anything, it’s the momentum you build up in that back-to-front motion, combined with proper technique and appropriate range, that are going to make you hit hard.
I can’t the scientific names for all these motions and ligaments and all that shit, but I sure as hell know what I see. And I’ve NEVER seen a guy punch significantly harder because he started doing squats.[/quote]
Here’s where we get technical…
Momentum = speed * mass
One study I read took a bunch of boxers and had them hit a force plate as hard as they could. They also measured the speed of the punch (high speed camera) and guess what they found? That the mass of the punch on very good boxers was almost equal to their arm weight! (momentum/speed = mass, then measure how heavy the arm is & compare.)
Translation: Boxers hit with their arms. All of them. Excellent boxers had nearly 100% of the arm mass in the strike. Nobody exceeded the arm mass in striking momentum.
Good boxers can get enough core stabilization to maximize this. The entire trick with punching harder is to go as fast as possible, keeping the core solidly behind the strike. Since even a little chaos where the punch lands can take away a lot of power, this is a lot trickier than it sounds, as any boxer (yes, I used to box and loved it) can attest.This is a timing issue so that at the moment of impact, the core is really solid. A split second either way and you lose power. Generating raw power with limbs will only help if the limbs get bigger AND you can control them. More, say, pushing power with punching won’t really patch poor core coordination (though it can give mediocre people a hobby while they suck. Oops, did I say that out loud?) It might, however, help to avoid injuries, so pushups, pullups, &c., &c., are good requirements to keep in your training.
Therefore, do squats help your punch with leg drive? Not per se, but the core stabilization involved in a good squat can have carry over. As I said in another post, I coach people to do a bout of squat training (standard of 3 - 6 months, then they are done), with an aim to improving mechanics, not raw power generation because of the timing involved in good striking (or throwing, or anything else in a martial art, for that matter). Only way to get good timing is to practice timing. Being freakishly strong can win the oddball bout but IMHO isn’t worth the training time enough to have as a regular part of the syllabus.

Edit: trying to track down the article, but I do recall the punch tested was a cross only.
