Pathetic attitude. Imagine that one of you came up with a new exercise machine. Not only that but you also built it and it worked. That would be an achievement. What do we see on this forum? Ridicule and scoffing.
Please don’t post condescending remarks based on broscience. I don’t acknowledge such rubbish.
Fair enough, that's a valid point.
I would come with a Hammer like chest press that allows you to start a press with your arms straight. I would also implement an mechanism to increase the load during the eccentric phase.
However... manufacturing, marketing & selling that machine would be a pain in the ass.
