What's your body type? 

You're an Ectomorph. You are often described as skinny or petite. You never gain weight, no matter what you eat, you lucky thing! However, you do have to be careful to maintain a healthy body weight and avoid osteoporosis and other health risks. Eat three meals a day and perform endurance activities such as walking or light jogging. Also try Hatha yoga and meditation.

You're a Mesomorph. Mesomorphs run the gamut from being lean and mean to simply being of average size and stature. The great thing about your body type is that you can gain muscle tone very easily, which probably makes you the envy of your friends. But you do have to be careful about falling prey to all-over weight gain, especially as you get older. You often have a great deal of energy and enjoy physical activity. Maintain a balanced diet and harness this vitality with team sports. Try Ultimate Frisbee, jogging, and kick boxing.
