1st and foremost, what purpose are you doing with this bench press? Are you trying to do strength for the big 3 or hypertrophy?
The answer will dictate your: 1. Amount of arch 2. Elbow Position 3. How high is your chest.
If you are going with hypertrophy, I think that form would be fine but if you are going with strength, yes you have a lot to fix (as per what Dave Tate video).
Haha, I just done watching Dave Tate's So you think you can bench. Really nice.
Um, I train for bodybuilding and strength but lean alot more towards bodybuilding. That's why my arch is not that high and my elbows are only tucked in 45degree.
I don't mind a slightly higher arch, which will cause more targeting to lower chest cause I'm also doing incline bench.
Umm, I think making the arch tighter and taking a wider grip will be sufficient fixes.
My advice would be, focus on a single goal. If you want to do hypertrophy, do a hyper trophy, same goes with strength. When you have become more experience, then you can start doing a hybrid or whatsoever as you have more knowledge on your body's mechanics.
