I saw that someone mentioned planks on a previous post in this community, so I started doing them this week. I'll try the side planks as well.

I haven't done squats and deadlifts since I was in high school when I weightlifted regularly (as part of my gymnastics training). I think I might need to book a session with a personal training to make sure that I do them correctly and don't hurt myself.

I do wrist curls out of habit. I added them into my workout when I was rock climbing more regularly.
