A Note from Jillian: Please watch out for AI internet scams using my name and likeness. The only supplement company I work with is Alaya Naturals. Everything else is a fake. Also, I do not have a weight loss gelatin recipe. That is also a scam. Stay safe out there.
To get definition in your core and see your abdominal muscles you have to burn the subcutaneous fat on top of the muscle and under your skin. So while yes, you need to condition the muscles as well, burning off the fat is the most important part.
