I am 5’7/ 170cm. I have rather long arms imho but if anyone doesnt think so thats fine. Im no expert lol. My palms rest just at my quads. Now when I bench I am trying to find my form and technique. Atm I feel leaving my feet a bit more tip toed than firmly flat. It feels more comfortable for me and gives me more of a spring board effect when I press making me use my core, hips and legs to help move the weight up. I will mention I have a metal plate in my left arm from an injury I got almost 10 years ago in a car accident. Keeping this in mind I try to figure out the best way I can move the most weight without compromising my left shoulder or arm and I feel as a recreational lifter working on getting my arch an inch or two up and moving the bar more more towards my stomach rather than just below my nipple line can activate more chest.
Here is a Picture of my bench set up and couple of videos of me benching. just slide right to see the next.
any tweaks and any answers relating to my question would be greatly appreciated.
