A skinny body is not always equivalent to a sexy body. Having the right curves means round buttocks, shapely legs and toned arms. If you have a skinny frame, you can gain weight through natural and safe methods. Exercise is the essential key to a healthy weight gain while still maintaining your curves like Jennifer Lopez and toned arms like Demi Moore.

Most women are afraid of too much exercise and weight lifting because they don't want to have bulging arms and thighs. The truth of the matter is, women can't have the same muscles like male bodybuilders simply because Mother Nature does not allow it. Women lack the testosterone needed to build those muscles. Don't believe in stories about women getting manly arms and legs after exercising. There is nothing to fear. A leaner body is your key to a sexier body with curves in the right places. Celebrities like Miranda Kerr and Jessica Biel know the value of toning your legs, arms and buttocks to maintain their sexy shape.

Why exercise at all?

Builds muscles

For effective weight gain, engaging in regular exercise will help build muscles, increase your metabolism and burn calories. Not only is exercise important in weight loss, it is also necessary in weight gain. Whether you prefer to work out at home or in a gym, you have to choose an exercise routine or sport to keep your body in shape.

Strength training exercises for weight gain involves some weight lifting using dumbbells to tone those scrawny arms. Regular exercise and physical activity helps in weight management and promotes a healthier lifestyle.

After an intense workout, you burn calories and use energy in your body. You will feel hungry and ready to eat food as much as you can. Use this time to gain weight by eating foods rich in protein as a muscle building block. The hungrier you get after strenuous physical activity, the more you can eat to gain more weight.

Improves sleep

Exercise also helps you sleep better. A good night's sleep is a requirement to maintain a healthy body. When your body gets used to the strength training exercises for weight gain, you will experience high energy levels to make you want to do more. Boosting your energy will give you the fuel to perform your weight gain exercises. The more sets you do, the faster you can build your muscles and tone your body the way you've always wanted.

Fat storage

Gaining more weight doesn't mean being overweight. There is always a difference between a healthy and obese body. Not many people know that muscle is actually heavier than fat. Eating just about anything in excessive amounts will cause you to gain excessive fat. This is harmful to your health due to a number of diseases associated with excess fat intake. You can eat foods rich in fat but in moderation. Your body will need to use fats and turn them to energy as you exercise.
