Bench Press Form Check

This is kinda repeating what meat has already said but there’s two things you should focus on first before you break down your technique even more. Fix your bar position in your hands. Keep the bar in line with your wrist and elbow it’s way too far back. Secondly forcibly press your heels into the ground, right now you’re not getting shit out of your arch except lessened range of motion, you have no leg drive. Driving your heels into the ground allows you to contract your quads and glutes easily, keeping your ass down but also bringing your chest up and providing you a more stable base. Right now you’re pressing through your toes, you want to press through your heels. It’s important to note your heels will not move but actively thinking heels down will keep them in place and tension through your entire body. The more you press your heels down the harder you should be able to squeeze your glutes. If you don’t have this experiment with toe angle and possibly bring your foot forward a little.

You should be benching wider. It takes time to get used to, but especially with an arch like yours benching wider will save your shoulders more than benching with a closer grip.
