You can follow a celebrity workout, but that doesn't guarantee that you will end up with Jennifer Lopez's physique. Any regular workout will make you fitter, healthier and happier, but remember that genetics also play a role in your body shape.
Health professionals have classified body types (for both men and women) into three general categories:

1. Endomorph: The endomorph shape tends to be rounded, and often goes along with small wrists and ankles and small facial features.
2. Ectomorph: The ectomorph shape features long legs and arms, narrow fingers and toes, and a delicate bone structure.
3. Mesomorph: A mesomorph type tends to have a naturally muscular chest and broad hands, with heavy bone and muscle development.

Similarly, body shapes fall into one of these four subcategories:

• Pear: Someone with this shape usually has narrow shoulders, a small chest, and average waist, and he or she tends to accumulate fat in the hips and thighs.
• Apple: Someone with this shape has a rounded tummy and thin arms and legs and tends to accumulate fat around the waist.
• Hourglass: Someone with this type tends to have a broad chest and hips and a small waist, and tends to accumulate fat in both the chest and hips.
• Inverted triangle or star: Someone with this shape has broad hips and chest but a small waist, and most of their body fat accumulates in the chest and hips.

Of course, not everyone falls neatly into one of these categories and most of us are made up of elements of more than one. Any of these types will become fitter with exercise. Just remember that no workout will make your short legs longer, but they will get stronger.
