You better create a Dtube account to share more about your daily workout. I'm sure many people would love to watch the instructions directly rather than giving some instruments here as you have successfully did for yourself.
It's a little bit hard to understand the steps without seeing the move right in front of our eyes.
Your explanation about Flat bench is well enough actually, but it would be more clear by providing a video.
Anyway it was horrible when a man didn't know much about the types of workout function, especially for the chest one. Gonna have two b**bs at the end .lol 😅
