Some of the best exercises you can do for the core involve stabilization. The job of the core is to stabilize the body. So, to strengthen that area, movements that emphasize stability, not mobility, are best. It’s why, often times the “After Party” involves additional core work in terms of hollow rocks, planks, Pallof Press, Turkish Get-ups, Hanging Knee Raises etc… Here’s a great link I found with some of our favorite core exercises all in one spot- some are super tough! 41 Hardest Core Exercises

I love that Overhead Squats are listed as I often say I could argue it’s one of the best exercises in terms of core activation.
