All Bench variants are unsafe so the answer to that is to take the least effective one and make it even more unsafe just to try and make it as effective as the others.... Can you please direct me to what kind of logic you used to get to that conclusion?
It's not the least effective one, it's at least better than incline based on the IEMG study cited before, which, with all its limitations, is far more solid evidence than forum lore.
I have not suggested anything that makes benching unsafer, quite the opposite, so I fail to see what you are talking about.
Here's an even better tip: don't make a minimally effective lift more dangerous.
Good tip, then why the hell do you proceed to describe a situation that can only occur when lifting without safety equipment? No barbell will crash down on your neck if the safety bars catch them first, and that holds for any bench variant.
Dips and dumbells are a great way to build muscle sure but neither of those is as time efficient or cost efficient as a bench press with a barbell.
Because you say so? Should have signed up for the premium plan at my gym which includes dumbell access and not just a barbell.
Yes benching is notorious for causing elbow and shoulder issues but here's another pro tip:
Work on mobility and form issues and they go away.
Or just do exercises that work just as well if not better and are less likely to injure you even if performed with a form that's not 100% textbook-correct. As a bonus you won't need safety equipment nor a spotter.
It's a bit more than opinion since your failed attempt at showing the decline is most effective variant.
More weight on the bar, so more muscle is being used. More activation of the lower pecs and equal upper pecs activation to the incline bench. Multiple ROMs to choose from. It's also harder to cheat on, since your feet never touch the ground.
Quite frankly I haven't seen in this thread any evidence the decline bench is not the least worst variant of what is, all in all, a very skipable exercise. So some people find the position awkward, and others don't think the benefits outweigh the costs, but those are preferences, or opinions, if you don't think you can perform it safely or that is a waste of time then don't do it. For me training is a form of recreation, do the exercises you enjoy to do, not what others say you must do.
