Engaging the core

So I am addicted to core exercises already that I wish it is held everyday in the gym. I honestly, I do not have the drive to them on my own. I want a trainer howling at me and I want to be surrounded by gym addicts like me. I missed the classes in the past two weeks and I was shocked to learn that they have advanced the lesson already. We were asked to use the core board and it was really freaking hard to balance. The main point of the core board is to do exercises that will strengthen the core. The routines that were taught to us felt like prenatal exercise. It was a killer workout but it feels good.
