Tks for sharing. Really informative. Can anyone provide some pointers on benching with a single ply bench shirt?

This video contains a lot of useful information, and surely the info from a IPF champions are always interesting because you have the chance to understand how a champion think.
However I really don't understand how is possible to transfer the reaction force, given from pushing the shoulders against the bench, to the barbell.
The point of application is the point of the contact of the shoulders on the bench. Indeed the reaction force have the same point of application, that is not the barbell.
Anyone can explain better this section of the video?

Don't worry, you're not misunderstanding physics. ;) The normal force isn't going to contribute. I think someone showed him a force diagram when the bar was racked and when it is in the lifters hands and he misunderstood what he was looking at. The rigid arch helps of course though.

That was quite excellent, I will be looking at his other videos as well. There were a few things I had been told to do, and I was doing them, I just didn't fully understand why I was doing them. Thank you for posting this tutorial video.

I hate the use of the term biomechanics to refer to lifting technique. Would you say a great bodybuilding coach who is an expert at adding muscle is a physiologist? Biomechanics is a field of science. But anyways, great tutorial thanks for sharing.

lol, ok, now it has a sense :D thank you!

I love the biomechanic terms! Because they are a formal way to describe something. They are precise, unique and well documented in literature. On the other hand, too frequently in gyms are used inappropriate terms that generate confusion and ambiguities.
Just last week, a fitness trainer, that claim to be a posturologist, tried to explain me that the bench press arch is bad and that my back would have disintegrated. And I have not found a way to explain my reasons, just because we did not have a common vocabulary.
I think that is a good way to communicate, without invent strange and fantasy terms.
