Running is great exercise to keep us thin and toned, but only with girly muscle. The thinner your waist, the more hips to waist ratio you have, which is the measure of female beauty. The hips to waist ratio is well known to signal fertility and the Black male response is raging hardness.
Work out, but only with girl weights. You want yours arms to be girly toned, but thin and weak, which triggers domination and protectiveness in Black men. Once you become a Black man's sissy, you'll be in much more contact with Black men and you will be doing anything they want, so it helps to have a protector.
