Here are 4 more Core Stabilization Exercises that are a little more advanced than the previous 6 exercise videos we posted earlier this fall. Please be sure that you are able to perform the Level One Core Exercises that we posted previously without difficulty before you attempt these new exercises. And remember that all exercises should be pain-free. Never push through pain or you might be creating injury! We have recommended starting with 8 repetitions of each exercise during the first several weeks. You may then perform 2 sets of 8 or rotate through the series twice resulting in 2 sets of 8.
