In order to develop a well rounded core, we need to perform exercises that target all of the four major areas. The main focus will still be on the abdominals and the obliques, but certain exercise variations will also benefit the transverse abdominis and the lower back, helping to increase stability and posture. A great core will benefit you in every athletic pursuit, and there’s no better time to build one than now.

Day 1

Test day. Today we’re going to perform a simple yet challenging ab circuit that will challenge your full core. The main goal of today is to test your baseline ab strength to see how much progress we’ll make throughout these next 30 days. Make sure to record how you perceived your performance and what your plank time was so you can see just how far you’ve come on day 30.

Week 1 is all about building up general core strength. It’s going to be a challenge, but hopefully not an overwhelming one. Use these exercises as a guideline and modify them if needed to fit your needs. The most important part of this week is just sticking with it, so only do as much as you can so you’ll be ready to come back each day.
