As a novice boxer who had previous martial art and sparring ability, I found myself regularly sparring Mark Demori. I'm sure we can all agree he wasn't on the same level as David Haye but rest assured he was an absolute monster in the local gym. I fractured my nose and eye socket in these Saturday morning melees until a blown disc took me out of the play for a while. That was when I first did starting strength and took my squat from 60kg to 140kg before going back to boxing. I remember Mark commenting to me on how he could no longer push me around the ring and showing me the scuff marks on his head from just blocking my punches after that layoff. Increased size and strength increases power, it's not rocket science.
Have you read the website long?
Rippetoe has never suggested lifting doesn't have diminishing returns. Quite the opposite. He has made explicit suggestions on how strong people should be for their sport. Crowder told Rippetote he did BJJ. Rip asked him his size. Then Rip told him how much he should be squatting.
Obviously everyone in this forum understands there are diminishing returns from strength training. Nobody thinks a figure skater would be best served in their sport by focusing primarily on a 1,000lb deadlift.
Are you trolling?
I did some boxing in high school.
I got stronger. Once stronger, I could punch much harder. As well, when my arms were hit by a sparring partner they didn't hurt as much.
Jon Jones recently talked about his first fight after taking up powerlifting, where Jones want from minimal lifting experience to squatting 500lbs.
His first fight after powerlifting, against Ovince St Preux, even though Jones had lots of ring rust and his rhythm looked a little off, Jones broke Preux's arm via kicks. Breaking an opponent's arm that way was a first for Jones, something that a weaker Jones had never been able to accomplish. Jones got strong and his striking got stronger. This stuff isn't complicated.
How is it a wrong assumption that boxers are doing the monkey fucking the football version of weight training when near every example you can find, even in sports that recognize the demand for more strength and try to use weight to get there, are doing it that way. People doing smart weight training is the minority in sports.
