Gynecomastia is the enlargement of male glandular breast tissue, distinct from pseudogynecomastia, which is fat-based. This distinction is why exercise affects one condition but not the other.
No. Exercise cannot remove gynecomastia because the condition is caused by glandular breast tissue, not fat.
You've cut carbs, you're benching more than ever, and the chest still hasn't changed. Why? Exercise can only help with pseudogynecomastia and can improve chest shape after surgery, but true gynecomastia requires medical or surgical treatment.
Medically reviewed by Dr Ivan Puah, Medical Director of Amaris B. Clinic and MOH-accredited liposuction doctor, has received dedicated training in gynecomastia surgery in the United States and liposuction training internationally. He created the 360°GTD® technique for optimal gynecomastia surgery results for patients from all walks of life. Dr Puah is also the leading author of a gynecomastia study in Singapore titled, "Surgical Management of Gynecomastia in Asian Men - Clinical Experience and Considerations for Different Patient Types."
Key Takeaway
- Exercise cannot eliminate gynecomastia because glandular tissue does not respond to exercise.
- While diet and training may reduce fat, the firm gland tissue behind the nipple does not respond to calorie deficits or workouts.
- Building chest muscle may potentially worsen the aesthetic appearance of gynecomastiaExercise may to a certain extent help with aesthetic conditions such as pseudogynecomastia by improving the chest contour.
- Physical symptoms of gynecomastia include pain, tenderness and even nipple discharge.
- Gynecomastia surgery is currently the only surgically proven permanent solution. It is often sought after many unsuccessful attempts with diet, exercise, and other treatments due to the psychological impact of the condition.
What Is Gynecomastia?
Gynecomastia (colloquially "man boobs") can occur in one or both breasts, often with tenderness around the breast and nipple.
"Gynecomastia, or the development of excess glandular tissues, can occur when there is a hormonal imbalance in men," says Dr Ivan Puah, medical director of Amaris B. Clinic.
Other causes include ageing and medication side effects.
Causes of Gynecomastia
Gynecomastia has four root causes:
Physiological
Patients may develop physiological gynecomastia due to hormonal imbalance in young adults, adolescents, or the elderly.
Pharmacological
Gynecomastia can be due to pharmacological causes, such as the use of anabolic steroids, or the long term consumption of certain types of medications such as anti-depressants.
Pathological
Very rarely, certain hormone-producing tumours, such as testicular or brain tumours, may lead to the development of gynecomastia. The underlying cause must be addressed to treat this group of patients.
Idiopathic
Gynecomastia is most frequently caused by idiopathic conditions without an established aetiology.
Physical & Psychological Pain of Gynecomastia
Gynecomastia affects men not just physically, causing pain, discomfort and breast swelling but more importantly, it affects them psychologically.
Adolescent gynecomastia may resolve independently, but regression is unlikely in many others. When it does not regress spontaneously, its unfavourable appearance may lead to significant social and psychological impairment.
Patients who suffer from gynecomastia may:
- Become so self-conscious that they avoid social activities, especially in environments requiring them to go topless, like swimming or chilling out by the pool or beach
- Withdraw from mixed-gender gatherings due to embarrassment and anxiety
- Refrain from intimacy, experiencing low libido or depression and mood swings that can affect relationships with partners
The embarrassment of having a feminised chest and the determination to get rid of it themselves is the primary reason why men with gynecomastia head to the gym to fix the issue.
Can Gynecomastia Go Away On Its Own?
Many assume gynecomastia always resolves on its own; but the percentage is rather low.
This misunderstanding frequently occurs because teenage boys can develop gynecomastia throughout puberty, which goes away in two years or less. In cases where gynecomastia persists for more than two years, it will likely become permanent.
Why Exercise Can't Reduce or Remove Gland Tissue
Three reasons working out doesn't fix gynecomastia:
1. Fat cells shrink with a calorie deficit; glandular tissue does not
Diet and exercise reduce body fat, but the firm gland tissue behind the nipple is a different type of tissue entirely and isn't affected by weight loss.
2. You can't spot-reduce fat, and you can't convert fat to muscle
When the body burns fat, it draws from stores across the entire body, not just the area being trained.
Fat and muscle are also biologically distinct tissues; one cannot be "turned into" the other, no matter how strict the diet or training program.
3. Building chest muscle can make gynecomastia more visible, not less
Bigger pectoral muscles push outward, which can make the glandular mass more prominent rather than hiding it.
Many patients who diet and train hard see their body weight drop while the breast tissue itself stays the same. If weight is lost quickly, they can end up with loose skin and stretch marks on top of the original problem.
Self-Check: Is It Glandular or Fat tissue?
Physically, you may notice breast soreness or discomfort; in some cases, discharge may occur.
Try a quick pinch and visual test to gauge the extent of the condition. If you feel a firm, fibrous mass when pinching the breast, that's likely gynecomastia.
An enlarged male breast is also highly visible when you're in a form-fitting shirt. In more severe cases, the breasts look like female breasts, with a degree of droopiness and loose skin present.
See a doctor experienced in treating this issue to assess your case and advise on next steps, whether that's further observation or gynecomastia surgery.
Gynecomastia Grades: Not All Cases Are the Same
Gynecomastia is classified into four grades based on severity:
Grade I
A small degree of breast enlargement in males, with localised tissue around the areola and a dark pigment area surrounding the nipple. Less noticeable with a top on.
Grade II (most common stage)
Moderate increase in breast size. At this stage, the tissue is already expanding sideways to the width of the male chest. Loose skin may be noticeable during physical activities or in tighter-fitting clothes.
Grade III
Moderate to significant enlargement of the breast, with more pronounced development of glandular tissue and fat, making the chest resemble a woman's breasts. Noticeable enlargement that may cause discomfort or embarrassment.
Grade IV
Substantial increase in breast size with a significant amount of excess skin and a more feminine breast appearance. Enlargement is severe, highly visible, and psychologically distressing.
| Grade | Signs |
|---|---|
| Grade I | Small enlargement; localised tissue around areola; dark pigment area; less noticeable with top on |
| Grade II | Moderate increase; tissue expansion across chest width; loose skin noticeable during activity or tight clothing |
| Grade III | Moderate–significant enlargement resembling women's breasts; noticeable discomfort or embarrassment |
| Grade IV | Substantial enlargement with excess skin; highly visible; psychologically distressing |
Gynecomastia vs Pseudogynecomastia: What's the Difference?
Pseudogynecomastia appears similar but they are entirely different. It is a distinctive condition, caused ONLY by fat deposits behind, around, and under the nipple, not glandular growth.
"Pseudogynecomastia is less commonly seen when compared to gynecomastia. For such patients, I will recommend weight management and lifestyle changes as the first-line treatment. When these methods don't work, liposuction is recommended," explains Dr Ivan Puah.
When Exercise CAN Help with gynecomastia
Exercise isn't useless here. It's just solving a different problem in specific situations:
| Situation | How exercise helps |
|---|---|
| General chest contour | Building pectoral muscle creates a more defined shape post gynecomastia surgery |
| Post-surgery maintenance | Enhances and preserves newly contoured chest shape |
How to Know If Exercise Isn't Working
Consider surgical evaluation if:
- You've lost significant weight, but the chest still looks prominent
- You can feel a firm mould under the areola area, which is usually a sign of enlarged glandular tissue
- You've trained consistently for more than 6 months with no chest improvement
- Building chest muscle has made the problem more visible, not less
Surgical Options When Exercise Fails
Many patients experience depression, anxiety, and low self-esteem, and have already tried dieting, exercise, creams, fat freezing, and low-energy lasers without success before turning to surgery.
Gynecomastia surgery is currently the only medically proven, permanent way to correct the condition.
Dr Ivan Puah, an MOH-accredited liposuction doctor with over 20 years of body sculpting experience and training in gynecomastia surgery in the United States, notes that the condition carries both psychological and physical tolls.
Each gynecomastia case is unique. The surgical approach developed by Dr Puah considers the grade of gynecomastia, the glandular tissue-to-fat ratio, and the patient's parenchymal distribution. He proposes an individualised approach after carefully assessing the patient's clinical condition and understanding their concerns.
Using his proprietary surgical approach, the 360°GTD®, to perform a clean excision of the excess glands, and the MDC-Sculpt®️ Lipo technique to remove unwanted chest fat, the surgery is carried out under local anaesthesia in an accredited Day Surgery. The patient is discharged home the same day.
Although some soreness and discomfort are expected as part of the post-surgical healing process, most of his patients describe the discomfort level as akin to overtraining.
Post-surgery, patients should avoid heavy lifting, bench presses, push-ups, and water-based activities until their doctor approves resuming training.

FAQ
Can push-ups get rid of man boobs?
No. Push-ups can strengthen and tone pectoral muscles; however, they cannot spot-reduce chest fat or glandular tissue. When the body burns fat, it does so systemically throughout the body, not just in the area being exercised. Furthermore, glandular tissues will not respond to push-ups and will not be reduced or removed through this means.
Can cardio or HIIT reduce man boobs?
Cardio and HIIT can reduce overall body fat, but they can't treat gynecomastia itself, since the condition is a distinct enlargement of glandular tissue rather than a simple result of being out of shape. In fact, many men find the condition appears more pronounced after weight loss because the fat around the gland shrinks first, making the gland itself more visible.
Does building chest muscle hide gynecomastia?
No, and it can backfire. Since gynecomastia is glandular tissue, building the pectoral muscles underneath can push the tissue further outward, making it more noticeable rather than less.
Is gynecomastia normal? How common is it?
Yes, gynecomastia is a common male medical condition, most frequently caused by idiopathic (unknown) factors, and it can occur at any life stage, including puberty, adulthood, and older age.
When can I exercise after gynecomastia surgery?
You can only begin exercising after your doctor clears you. Heavy lifting, bench presses, push-ups, and water activities should be avoided until then to protect the recovery process.
Can a cold compress reduce swelling from gynecomastia?
Only temporarily to ease soreness due to physical symptoms of gynecomastia but cannot reduce or remove the glandular tissues or flatten the chest.
What is the typical cost of gynecomastia surgery in Singapore?
Gynecomastia surgery in Singapore costs from SGD $4,500, depending on the severity of your condition (grade), facility type, anaesthetist's fee, type of anaesthesia used, and the surgical technique required.
Are steroid users specifically at higher risk of getting gynecomastia?
Yes, the use of anabolic steroids is a well-documented contributing factor to the development of gynecomastia, hence men who use steroids are at a higher risk. Anabolic steroids can convert to estrogen, disrupting the hormonal balance and stimulating breast tissue growth. Unfortunately once the glandular tissue develops, it is usually permanent and will require surgical removal.
Is gynecomastia covered by insurance or MediSave in Singapore?
Although gynecomastia is a recognised medical condition worldwide, it may not always qualify for insurance coverage unfortunately. The key factor is whether the surgery is deemed medically necessary rather than purely cosmetic.
Singapore Citizens and Permanent Residents can utilise part of your MediSave for gynecomastia surgery costs, depending on the condition's cause, severity, and symptoms provided:
- The surgery must be medically necessary.
- The procedure must be performed at an MOH‑accredited facility.
- Proper medical documentation from an accredited institution is essential for MediSave withdrawal.
MediSave does not cover treatments that are for non‑medical purposes, such as those for cosmetic or lifestyle reasons. MediShield Life explicitly does not cover cosmetic surgery.
Private insurance coverage depends on the specific policy terms and the determination of medical necessity.
Patients considering gynecomastia surgery should check with their insurer directly to understand their plan such as specific coverage, exclusions, and out‑of‑pocket costs.
