Does Hip Size Increase? Understanding the Factors That Shape Your Body

4 min read

Research has found that, contrary to common belief, the pelvis can continue to grow and widen slightly for decades after a person reaches skeletal maturity, typically around age 20. This surprising anatomical fact is just one piece of the complex answer to the question, 'Does hip size increase?,' which also involves genetics, body composition, and lifestyle.

Quick Summary

Hip size changes are influenced by genetics, bone structure, and factors like muscle mass and fat distribution. While bone width is largely set after puberty, apparent hip size can be altered through targeted exercise, diet, and weight management. Hormonal shifts also play a significant role throughout different life stages.

Key Points

  • Genetics Set Bone Structure: The core width of your hips is determined by your pelvic bone structure, which is genetically inherited and set after puberty.

  • Pelvis Can Widen with Age: Studies indicate that hip width can naturally increase slightly with age, even after skeletal maturity, particularly for women.

  • Childbirth Can Increase Hip Size: The pelvic joints of women can widen during childbirth, and this change can sometimes be permanent.

  • Muscle Growth is Key for Shaping: Building the gluteal muscles, especially the gluteus medius, through targeted exercises can increase volume and create the appearance of wider hips.

  • Fat Distribution Affects Appearance: Gaining weight can increase hip size, as body fat is stored in specific areas based on genetics and hormones like estrogen.

  • Hormones Influence Fat Storage: Hormonal shifts during life stages like puberty and menopause significantly affect where fat is distributed, impacting hip circumference.

  • Targeted Exercise and Nutrition: A combination of resistance training and a protein-rich diet is the most effective lifestyle-based approach to increasing apparent hip size.

The question of whether hip size can increase is a common one, with the answer being more complex than a simple yes or no. The overall size and shape of your hips are determined by a combination of skeletal structure, muscle mass, and fat distribution. Understanding the interplay of these factors is key to knowing what can be changed and what is largely fixed by your genetics.

The Role of Bone Structure and Genetics

Your skeletal frame provides the fundamental structure for your body, and your hip bones (the pelvis) are a major component of this shape. The width of your pelvis is primarily determined by genetics and largely fixed after puberty. However, this isn't the whole story.

Pelvic Growth with Age

Recent research has shown that the pelvis, and therefore hip width, can naturally and slowly widen as a person ages, well into their 70s. The pelvic width of older individuals has been found to be, on average, larger than that of younger adults. This phenomenon is a natural process not necessarily linked to weight gain.

Childbirth and Hip Expansion

For women, another natural process that can affect hip size is childbirth. The pelvic joints widen to allow for birth, and for some women, this widening can be permanent. This is a physiological change that cannot be achieved through exercise or diet.

The Influence of Body Composition

Beyond bone structure, the soft tissues surrounding the pelvis—namely muscle and fat—are the most significant and controllable factors affecting hip size. By targeting these tissues, you can modify your body's silhouette.

Increasing Muscle Mass

The gluteal muscles are the largest muscle group in the hip and buttock area and are a primary target for those looking to increase hip size. The gluteus medius, in particular, is a key muscle for creating the appearance of wider hips. Through resistance training and a proper diet, these muscles can be built up, adding volume and a curvier shape. To achieve muscle growth, known as hypertrophy, you must consistently challenge the muscles and provide them with enough protein and calories to rebuild and grow stronger.

Fat Distribution and Storage

Where your body stores fat is largely determined by genetics and hormones. Women tend to store more fat in the hips, thighs, and buttocks due to higher estrogen levels, especially after puberty. A controlled increase in body weight through a balanced, calorie-dense diet can lead to fat accumulation in these areas, thereby increasing hip circumference. It's important to understand that this is not 'spot-gaining' fat, but rather a general weight gain where your genes dictate where the fat is deposited.

Hormonal and Lifestyle Factors

Throughout life, hormonal fluctuations and lifestyle choices impact body composition and shape.

  • Estrogen: High levels of this hormone, particularly during puberty and pregnancy, promote fat storage in the lower body, including the hips and buttocks.
  • Aging: As people age, hormonal changes—especially after menopause in women—can cause fat to redistribute from the hips and buttocks towards the abdomen. This can make the hips appear narrower.
  • Diet: The right nutrition is critical for supporting muscle growth or healthy weight gain. A diet rich in lean proteins, healthy fats, and complex carbohydrates provides the fuel needed for exercise and recovery.
  • Exercise: Regular physical activity not only builds muscle but also improves overall body composition. Targeted exercises can sculpt the muscles around the hips, contributing to a more toned appearance.
  • Sedentary Lifestyle: Prolonged sitting can lead to weaker gluteal muscles and can negatively affect body composition, potentially reducing apparent hip size over time.

Comparison of Hip-Building Methods

Method Mechanism Predictability & Control Permanence Associated Risks
Targeted Exercise Builds gluteal muscles (gluteus medius/maximus) with resistance training. Controlled, but limited by genetic muscle attachments. Maintained with consistent training; reversible. Low risk (potential for injury from poor form).
Weight Gain (Diet) Increases overall body fat, which is distributed according to genetics. Low predictability for specific hip fat placement. Depends on maintaining weight; reversible. Health risks if weight gain is unhealthy.
Cosmetic Surgery Involves fat grafting (BBL) or implants for direct volume addition. High predictability and targeted results. Fat grafting may lose some volume; implants are permanent until removed. High risk (infection, complications, fat embolism).

Targeted Exercises for Hip Development

Incorporating specific exercises into your routine can help build the gluteal muscles, contributing to a fuller, rounder, and potentially wider-looking hip area.

  • Hip Thrusts: An excellent exercise for targeting the gluteus maximus to build power and volume.
  • Squats (Weighted): A foundational lower body exercise that works the glutes, quads, and hamstrings. Variations like sumo squats can place a greater emphasis on the hips and inner thighs.
  • Side Lunges: Focuses on the gluteus medius and inner thighs, which helps with hip abduction and width.
  • Banded Lateral Walks (Monster Walks): Using a resistance band to create tension while walking side-to-side specifically targets the hip abductor muscles.
  • Donkey Kicks: An isolation exercise that effectively targets the gluteus maximus for focused muscle growth.
  • Clamshells: Strengthens the gluteus medius and improves hip stability by working the abductor muscles.

Remember to pair your workouts with a diet rich in protein to fuel muscle repair and growth. For professional guidance, a certified personal trainer can help you create a customized plan.

Conclusion

Ultimately, whether hip size increases is dependent on the specific factor being examined. The foundational width of your hip bones is largely set by your genetic inheritance, though minor changes due to age and childbirth are possible, especially for women. However, the most significant and noticeable increases in hip size are achieved by strategically building muscle and managing body fat. Through a combination of targeted resistance exercises and proper nutrition, individuals can effectively influence their overall body shape within their genetic potential.

Frequently Asked Questions

No, you cannot naturally increase your hip bone (pelvic) size significantly through diet or exercise after puberty. Bone width is primarily determined by genetics. However, research indicates a slight natural widening can occur with age, and childbirth can permanently alter pelvic size in some women.

Exercises that target the gluteal muscles are best for increasing hip size. Effective exercises include hip thrusts, weighted squats, side lunges, clamshells, and lateral walks with resistance bands.

Yes, weight gain can increase hip size, especially for women who are genetically predisposed to store fat in the hips and thighs due to estrogen. However, you cannot control where the fat is deposited, as it is determined by genetics.

Hormones like estrogen play a significant role in fat distribution. Higher estrogen levels during puberty promote fat storage in the hips and buttocks, contributing to a curvy figure. Post-menopause, lower estrogen can lead to fat redistribution towards the abdomen.

Significant increases in hip size without gaining weight elsewhere is challenging. While building muscle mass in the glutes can add volume, a calorie surplus is required for muscle growth, which may lead to some fat gain throughout the body. Genetics will determine how fat is distributed.

Yes, cosmetic surgery can increase hip size. The two main types are fat grafting (Brazilian butt lift) and hip implants. Fat grafting involves transferring fat from other body areas, while implants are semi-solid silicone devices.

Achieving noticeable muscle growth takes time and consistency. With a targeted workout routine and proper nutrition, you can expect to see gradual changes over a period of several months, not weeks.
