????? wtf
foot placement is extremely important for one, i can change my placement to get a bigger arch and get more leg drive and bench 20lbs more. why are you in a thread about correct benchpress form if you are dishing out advice like this, you "dont even touch your chest" cmon man wtf
The context of powerlifting vs. bodybuilding makes a big difference. I am not a powerlifter at all. That being the reason I don't touch my chest. I don't need to. I should specify that I don't touch my chest when I am lifting a heavy weight (full rep weight or a max). If I lift a light weight to warm up I bring it all the way down to the chest just to get everything loose and warmed up. Once I stack on the plates, I don't bring it all the way down to my chest. probably 2-3 inches above. That's already far past 90 degres on my arms.
If you are talk powerlifting, yes, you should always touch your chest everytime. You have to to complete a "full rep". If you are a body builder and not necesarrily concerned about presing 500lbs for a score, then you don't need to bring the bar to your chest if you don't feel comfortable doing it. You can get the growth stimulation without touching your chest.
Although this isn't always the best example to use, if you watch pro bb'ers and many of them don't touch the chest when they lift. You can find many videos on youtube of ronnie, jay, big name guys etc. not touching the chest and BarBell bench. It even looks like they are using a very small range of motion sometimes.
If you are a bodybuilder, it's up to you if you touch the chest or not. If you like it and it works, then go for it. If you don't like it, then you don't have to do it.
As for the feet placement, my comment was stupid. I realize that. What was on my mind and what I said didn't exactly reflect eachother and i didn't think it through. Obviously you wouldn't put your feet in a real goofy position like up in the air or indian style on the bench. I would assume everyone just puts their feet comfortably on the ground. If you are looking the do as much weight as possible, I guess you drive with your legs. I never really thought about it like that. I focus on using my chest as much as possible in the excercise as opposed to just ramming the weight up and down.
