What you put in your tummy shows!!!
Heard about starvation mode. Did you know that fluid is a huge cause for that wobbly belly? If you don't drink enough water, your body stores some for when you need it - and geuss where it is held most commonly - in the tummy!
And remember what you eat is even more important than those sit ups. Eating good fats and proteins and cutting down on the sugar and bread, the treats we all, love will show a huge improvement.
Also taking flaxseed oil regulary helps to get the hormones under control which can also effect the fat and fluid throughout your body.
