"Spot reduction" is a myth – for men or for women – a physiological impossibility; the overall amount of fat is just that, an "overall" condition – the result of too much food and-or too little exercise.
But in certain sections of the body of women or men, a very noticeable degree of "apparent spot reduction" can be produced.
When a fat appearance is a result of poor muscle-tone, as it frequently is – particularly in young women, but not uncommonly in men – then literally spectacular "apparent results" can be produced if direct exercise is applied to that area of the body; with little or no change in the body weight, and no measurable reduction in the actual fat content of the body – and with no change in the diet.
And without increasing the size of the involved muscles to any noticeable degree – and with no increase in the size of other muscular structures in the body.
Since this condition is most commonly developed in the upper-thighs and in the buttocks, and since conventional exercises for these muscles involve working the much larger muscles of the frontal thighs as well as the muscles you are actually trying to reach – exercises such as squats and leg presses – and since most women are not anxious to increase the overall size of their thighs (even if they are willing to use such hard exercises, and few are), it is obviously necessary to provide some form of direct exercise for the buttocks and upper-thigh muscles that work in connection with each other.
