I just started lifting recently and I had a question about bench pressing that the sticky didn't answer. Do I really need to arch my back while benching? I'm not doing it to the degree of pic related obviously, but it doesn't feel like it's adding anything to my strength towards pressing the bar up and felt no different from when I tried it without the arch. Is the arch something meant for people trying to squeeze every ounce of power out to press the bar, or is it truly integral at all stages? It just feels a bit silly arching my back to bench only 75lbs.

yes u HAVE to arch ur back just like in pic or u die

You should have a slight arch, it helps keep your shoulders in a safe and stable position and helps you more efficiently transfer energy into the barbell.

>Wearing knee sleeves and deadlift shoes to bench
You don't need to arch unless you compete. You do need to keep your lower body tight. No dancing feet.

but Opie say he bench no arch! Then who was Opie?

If you retract your scapula like you should to protect your shoulders, you'll naturally have a slight arch.

Should I jerk my back while deadlifting?

as hard as you can. While it's rare, if you can get the legendary "back-snap" to happen, that's your body releasing raw paleolithic hunter-gatherer testosterone and you'll double your gains within a month or less.

Okay. Thank you!

You're a dumbass if you actually bought that.
