Changing Body Shape: Can You Change Your Body Type?
Many women wonder if they can change from a pear to an hourglass, or from an apple to a rectangle. Here's the science behind what you can—and can't—change about your body shape.
The Short Answer
You cannot fundamentally change your body shape. Your bone structure— shoulder width, hip width, rib cage size—is determined by genetics and cannot be altered. However, you CAN change how your body looks within your genetic framework through exercise, diet, and lifestyle.
Think of it this way:
Your body shape is like a house's foundation. You can renovate the interior, change the paint, and add furniture, but the foundation stays the same. You can build muscle, lose fat, and improve posture, but your underlying structure remains.
What You CAN Change
Muscle Mass
Building muscle can significantly change your silhouette. Shoulder exercises can broaden a narrow upper body. Glute exercises can add curves to a flat backside. Core work can create a more defined waist.
Body Fat Distribution
While you can't spot-reduce fat, overall fat loss changes how your shape appears. Losing weight can make your waist look more defined relative to your hips and bust.
Posture
Good posture can make you look taller, more confident, and change how your body shape appears. Slouching makes shoulders round and belly protrude.
How You Dress
Strategic clothing choices can create optical illusions—adding curves, minimizing areas, and creating the appearance of different proportions.
What You CANNOT Change
Bone Structure
Your skeletal frame is fixed. If you have wide hip bones, you'll always have wide hip bones. If your shoulders are narrow relative to your hips, that ratio stays constant.
Height
Once you've finished growing (usually by early 20s), your height is fixed. Petite or tall, this affects your overall proportions and can't be changed.
Fat Distribution Patterns
WHERE your body stores fat is genetic. If you tend to gain in your hips, that tendency remains even if you lose overall weight. You'll always be a "pear gainer" or "apple gainer."
How Exercise Affects Each Body Shape
Apple Shape + Exercise
Exercise can help apples by reducing overall body fat (including belly fat) and building muscle in the legs and glutes. However, apples will still tend to carry weight in the midsection.
Best exercises: Cardio for fat loss, leg/glute work for lower body balance
Pear Shape + Exercise
Pears can build upper body muscle to balance proportions and reduce lower body fat through cardio. However, the pear tendency to store fat in hips/thighs remains.
Best exercises: Upper body strength training, HIIT for fat loss
Rectangle Shape + Exercise
Rectangles benefit most from targeted muscle building. Shoulder and glute work can create the appearance of curves that aren't naturally there.
Best exercises: Shoulder presses, lateral raises, squats, hip thrusts
Hourglass Shape + Exercise
Hourglasses can maintain their curves with balanced exercise. Core work can make the waist appear even more defined without building bulk there.
Best exercises: Full body strength training, avoid excessive oblique work
Inverted Triangle + Exercise
Inverted triangles can build lower body muscle to balance broad shoulders. Heavy glute and leg work creates more proportional appearance.
Best exercises: Heavy squats, lunges, hip thrusts, avoid shoulder building
Life Events That Change Body Shape
While your fundamental body shape stays constant, these life events can shift how it appears:
Puberty
Hormones trigger fat redistribution and bone growth. A girl who was a rectangle might develop pear characteristics as estrogen kicks in. Body shape typically solidifies by early 20s.
Pregnancy
Pregnancy can permanently widen the hips and ribcage. Many women shift slightly toward pear or hourglass shapes after having children, even if they return to pre-pregnancy weight.
Menopause
Declining estrogen causes fat to shift from hips/thighs to the midsection. Many pear and hourglass women notice apple-like changes. This is hormonal and largely unavoidable without hormone therapy.
Significant Weight Change
Major weight gain or loss can reveal a different-looking shape. Someone who thought they were an apple might discover they're an hourglass after losing weight. The underlying structure was always there.
The Role of Genetics
Your body shape is approximately 70-80% determined by genetics. This includes:
- •Bone structure and proportions
- •Where you tend to store fat
- •Muscle fiber composition
- •Metabolism speed
- •Hormonal balance tendencies
Look at your biological family members. If your mother and sisters are pear-shaped, chances are you are too. This isn't destiny—lifestyle matters—but it sets the baseline.

Frequently Asked Questions
Can you change your body shape with exercise?
You can change how your body looks with exercise by building muscle and losing fat, but you cannot change your underlying bone structure. Exercise can make an apple shape appear more toned, add curves to a rectangle shape through muscle building, or slim down a pear shape, but your fundamental proportions remain.
Does your body shape change with age?
Yes, body shape often changes with age due to hormonal shifts, metabolism changes, and muscle loss. Many women shift toward an apple shape during menopause as fat redistributes to the midsection. Pregnancy can permanently widen hips. Maintaining muscle through exercise can help minimize age-related changes.
Can losing weight change your body shape?
Weight loss changes how your body looks but rarely changes your fundamental shape. If you're a pear shape, you'll likely remain a pear shape when you lose weight—just a smaller pear. Your genetic fat distribution patterns stay the same. However, significant weight loss can sometimes reveal a different shape than expected.
Is body shape genetic?
Yes, body shape is largely genetic. Your bone structure (shoulder width, hip width, rib cage size) is determined by DNA and cannot be changed. Fat distribution patterns are also genetic—some families tend toward pear shapes, others toward apple. However, lifestyle factors like diet and exercise influence how your genetic shape manifests.
Can hormones change your body shape?
Yes, hormones significantly affect body shape. Estrogen promotes fat storage in hips and thighs (pear distribution), while testosterone promotes upper body fat and muscle. Hormonal changes during puberty, pregnancy, and menopause can shift fat distribution and change how your body shape appears.
