Strengthening your legs through weight training exercises has many advantages. Not only are your legs supporting your body in daily activities and sports, a strong lower half is crucial if you want to strengthen your upper muscles. When you exercise your quadriceps and other leg muscles through exercise, your buttocks often participate in the movement. Although you will strengthen your glutes, you will not have to buy bigger pants.
Less fat, more muscle
Physical conditioning can raise your basal metabolic rate and help you burn fat, which means that this type of exercise can, in fact, help decrease the size of your bottom if you there was more accumulated fat. Exercises such as the leg press and deadlift are designed to exercise your quadriceps and hamstring muscles, respectively, but the glutes are also used. Technically, you can use these exercises to slightly increase the size of your butt. However, if you do cardiovascular exercise and conditioning with weights to burn fat, you are more likely to notice a decrease in the size of your butt, even if at the same time you are increasing the size of your muscles.
