Legs, Hips and Gluteals
Strong, powerful legs give your body good symmetry, balancing the development of the upper body, and facilitating good performance in other sports.
Building a good foundation of strength in the lower body is important in all sports that require running, jumping, lifting, kicking and pushing. Hip and leg extension play a major role in:

Running - as seen in athletics, football and rugby.
Jumping - as seen in volleyball and netball.
Kicking - as seen in football and the martial arts.

Chest
The desire for a bigger, better-developed chest is perhaps the greatest motivator for men to strength train. It somehow symbolizes heroism and male virility. Women, too, can benefit from chest training. Although it won't increase the size of your breasts (they are mostly fat tissue), it will create the appearance of a fuller and more shapely chest.

Strong chest muscles are advantageous in many sports. These muscles are involved in all forward and upward-reaching actions ­e.g. in rugby tackling and grabbing an opponent- and are also used in throwing and hitting movements - e.g. during forehand drives in tennis and squash; when throwing the ball overhead in netball, basketball and volleyball; and throwing the discus, shot-put and javelin. A strong chest is also advantageous in swimming (breaststroke) and several gymnastic disciplines.

Shoulders
Shoulder training can change the proportions of your physique. Well-developed shoulders draw more attention to your upper body and create an aesthetically pleasing taper, making your waist appear smaller.
Strong shoulders are advantageous in most sports involving upper body motions. The shoulder muscles are involved in:

Raising the arms forwards or sideways away from the body - e.g. tennis or squash strokes, and front crawl in swimming.
You need to use a variety of exercises to train your shoulders as there is no single exercise that works the whole area. The shoulders are comprised of three heads each of which needs to be targeted if you want full and well balanced development.
