The abdominal region can only “tone” so much. You can do abdominal exercises all day, however the desired effect will not be reached until you lock in your nutrition. A well balanced diet will help provide the tone look you desire. Everyone has abs, they are usually just hidden under a layer of subcutaneous fat!
“Toned” is one of those terms that is used a lot, but I honestly have to dig deeper when someone asks me about how to achieve it because its such a vague term. What I find is that many people are searching for a way to spot-reduce a specific area of their body.
By “flat, toned mid-section” do you mean that you have excess belly fat that you’d like to lose? Or have you recently had a baby and need to recondition abdominal muscles?
