Does Running Shrink Your Bum? Truth Revealed!

Have you ever wondered if those long runs on the treadmill or through your neighborhood park are secretly working to shrink your bum? You are not alone! 

You will never need to worry about this concern anymore because, in this blog post, we will uncover the truth about the relationship between running and the size of your bum. So, read on!

Key Takeaways:

  • Running impact on buttocks varies: shrinks with distance, enlarges with intensity and strength training.
  • Genetics and diet influence butt size, running can’t change genetic predisposition.
  • Different types of running engage glute muscles differently for growth and endurance.
  • Consistent, progressive running routine with strength training can improve bum appearance.
  • Running itself won’t cause bum sagging; strength training helps prevent and lift the bum.
  • Running offers psychological benefits like stress reduction, boosted self-esteem, and improved mood.

The Impact of Running on Your Bum

Running can either shrink or enlarge your buttocks depending on the type of running you do and various factors, including genetics, running intensity, and diet. Here are the differences:

Running Shrinks Your Bum

Running does not specifically target the buttocks, but it can shrink them due to calories burned and fat loss throughout your body, including your gluteal region. However, this can vary from person to person, as genetics significantly affect where your body stores and loses fat.

Distance running is the perfect type of run that can mainly shrink your bum. 

A study has found that exercise like running can reduce belly fat, even without changing your diet.

Running Enlarges Your Bum

Running can enlarge your butt when the type II muscle fibers that are larger and more able to increase muscle size activate.

This can happen when you run uphill or incorporate interval training into your routine, as they particularly target the glute muscles.

Uphill running requires more effort from your glutes to propel your body upward. At the same time, interval training can provide a more intense workout for the muscles in your lower body.

Note that running alone may not be the most effective approach. Try to incorporate strength training exercises that target the gluteal muscles (such as squats, lunges, and deadlifts) to further increase the muscles and size of your buttocks.

In a 2021 study featured in the “International Journal of Environmental Research and Public Health,” researchers determined that a twelve-week regimen of high-intensity training, whether centered around running or functional exercises, yielded positive outcomes. These included a reduction in body fat percentage and an enhancement of aerobic capacity in previously sedentary women who participated in the study.

Bum-Shrinking Factors: What Influences Your Glute Size?

Diet: Diet is crucial for the size and appearance of your buttocks. If you’re running to lose weight and maintain a calorie deficit, you may experience a reduction in the size of your buttocks due to fat loss. Conversely, if you consume excess calories and protein, you may promote muscle growth in your glutes.

Genetics: Genetics significantly influence the shape and size of your buttocks. Some individuals naturally have smaller or flatter buttocks, while others have genetically larger or more rounded buttocks. 

Running can help improve muscle tone and reduce fat, but it cannot change your underlying genetic predisposition for butt size and shape.

Different Types of Running and Their Benefits

Here are the types of running and how they affect muscle engagement and growth in the buttocks:

Steady-State Running: Steady-state running, characterized by a moderate and consistent pace, primarily engages the muscles necessary for sustaining that pace, such as the gluteal muscles. However, it doesn’t offer the same level of muscle activation as more intense running forms. 

Interval Training: Interval training involves switching between high-intensity running and recovery periods, significantly engaging the gluteal muscles, especially during high-intensity intervals due to rapid acceleration and deceleration. 

It effectively targets Type II muscle fibers, which have greater growth potential, making it conducive to muscle growth in the buttocks. 

Uphill Running: Running uphill demands increased effort from the gluteal muscles to overcome gravity, making it an effective means of targeting and strengthening these muscles. 

Downhill Running: Downhill running involves eccentric muscle contractions, where muscles lengthen under tension. 

While it engages the gluteal muscles differently from uphill running, it still contributes to overall gluteal muscle endurance and strength, particularly during the eccentric phase of each stride. However, it may not promote muscle growth as much as uphill or interval running.

Transform Your Butt with this Running Workout Routine

It is essential to establish a consistent and progressive running routine to notice changes in the appearance of your buttocks due to running. 

The frequency of your runs should align with your overall fitness goals, whether you want to reduce body fat or build and tone your gluteal muscles. Here are some general guidelines:

Beginner Level

If you’re new to running, start with 2-3 days of running per week, with each session lasting around 20-30 minutes. Focus on building your endurance and gradually increasing your running time and intensity over several weeks.

Fat Loss and Toning

To see changes in the size and firmness of your bum, consider running at least 3-4 days a week. To enhance the results, combine running with strength training exercises that target the glutes, such as squats and lunges.

Incorporate both shorter, high-intensity runs and longer, steady-state runs for a well-rounded approach.

Advanced Level

If you’re already an experienced runner, you may need to run 4-6 days a week or follow a more structured training plan to achieve specific goals. Professional athletes and dedicated runners often have more frequent and intense training schedules.

Note: Regardless of your fitness level, it’s crucial to incorporate rest days into your routine to allow your muscles to recover. 

Potential Risks and Injuries Associated with Running

Common running-related injuries include:

Runner’s Knee (Patellofemoral Pain Syndrome): A common overuse injury that causes knee pain.

Shin Splints: Pain along the shinbone due to inflammation of the muscles and tendons.

Plantar Fasciitis: Refers to the irritation of the tissue that stretches along the underside of the foot, resulting in discomfort or pain in the heel area.

Achilles Tendonitis: Inflammation of the Achilles tendon resulting in heel and calf pain.

IT Band Syndrome: Irritation of the iliotibial band, leading to outer knee pain.

Here are ways to prevent injuries: 

Proper Warm-Up: Always warm up with dynamic stretches to prepare your muscles.

Gradual Progression: Increase running intensity and distance gradually to avoid overuse injuries.

Proper Footwear: Ensure you have suitable running shoes with support and cushioning.

Cross-Training: Incorporate other forms of exercise to reduce the risk of overuse injuries.

Listen to Your Body: Pay attention to pain or discomfort and rest when needed.

Stretching and Strength Training: Include regular stretching and strength exercises to maintain muscle balance.

Consult a Professional: Seek advice from a physical therapist or healthcare provider if you experience persistent pain or injuries.

Psychological and Motivational Benefits of Running

Running offers numerous mental benefits, including:

Stress Reduction: Running can reduce stress and improve mental well-being.

According to David Linden, a neuroscience professor and author of the book Unique: The New Science of Human Individuality, engaging in aerobic exercise, regardless of age, has antidepressant effects and can aid in mitigating cognitive decline as we get older. 

Boosting Self-Esteem: Achieving fitness goals through running can boost self-esteem and body confidence.

Motivation and Discipline: Regular running instills discipline and motivation, which can spill over into other aspects of life.

Mood Enhancement: Running releases endorphins, improving mood and overall mental health.

Will Running Cause My Bum to Sag?

Running itself does not cause bum sagging. In fact, a regular running routine combined with strength training exercises can help improve bum firmness and prevent sagging.

However, it’s essential to understand that running is a high-impact exercise that may lead to some muscle soreness, especially if you’re just starting. This soreness can temporarily affect the feel of your bum, but it’s not a sign of long-term sagging. 

It’s crucial to incorporate strength training exercises that target your glutes, such as deadlifts and squats, into your fitness routine to mitigate this. 

Can Running Give Me a Lifted Bum?

Running engages the muscles in your lower body, including the gluteal muscles. As you run, these muscles are actively contracting and working to propel you forward. 

Over time, regular running can help strengthen and tone the gluteal muscles, leading to a lifted appearance of your buttocks.

However, running alone may not provide the same degree of bum-lifting benefits as targeted strength training exercises like squats and lunges.

Always listen to your body, and if you have specific fitness goals, consider consulting with a fitness professional to create a tailored workout plan that aligns with your objectives.

Are You Running Your Way to a Smaller Bum?

The impact of running on your bum is a multifaceted matter influenced by various factors such as genetics and diet. Running, particularly distance running, can lead to fat loss throughout your body, potentially reducing the size of your buttocks. 

Conversely, running can enhance your bum, primarily when engaging in uphill running and interval training. These exercises activate the gluteal muscles, promoting muscle growth and a more lifted appearance. Yet, for substantial muscle development, incorporating targeted strength training exercises is advisable.

Note that running itself does not cause bum sagging, but incorporating strength training can help prevent it. So, start your fitness adventure that can not only transform your bum but also boost your overall health and well-being!
