Armpit Fat: Causes, Exercises & Best Treatments

We’ve all noticed it at some point. That little bulge near the armpit that peeks out when we wear certain tops. It’s not dangerous, but… it can feel annoying, even distracting. At our clinic, we’ve met plenty of people who just wanted to feel more comfortable in their skin, and honestly, we get it. Armpit fat isn’t just about weight- it’s a mix of things, sometimes even beyond our control. In this guide, we’ll walk through the main causes, exercises, and both surgical and non-surgical ways to deal with it. We’ll also look at when a skin treatment might help more than workouts.

What is Armpit Fat?

Armpit fat is that small area of extra tissue between your chest and your upper arm. It’s sometimes soft, sometimes firmer, and it can be made up of fat, loose skin, or even something called axillary breast tissue. The tricky part? It doesn’t always shrink easily, even if the rest of the body gets leaner.

Some people notice it more after weight gain. Others, strangely enough, after weight loss- because the skin may sag. It’s not exactly harmful, but it can be frustrating if you feel it changes how clothes fit.

It’s worth noting that not every bulge here is “fat.” Sometimes it’s swollen lymph nodes, a muscle fold, or an entirely different tissue type. Understanding which it is can help decide what approach works best.

Common Causes of Armpit Fat

We wish there was one simple answer, but it’s often a mix of things.

1. Genetics– Some of us naturally store more fat in the upper body. If close family members have it, there’s a good chance we might too.
2. Weight Gain– Obvious but worth mentioning. Extra fat can settle in areas we least expect.
3. Hormonal Changes– Shifts in estrogen and progesterone can lead to fat redistribution, sometimes ending up near the armpits.
4. Poor Posture– Slouching can make skin folds look more pronounced.
5. Loose Skin– This often happens after sudden weight loss or as we age. Skin loses elasticity, so it hangs a bit.
6. Axillary Breast Tissue– A small percentage of people are born with this extra breast tissue extending into the armpit area.
7. Lymphatic Swelling– Though less common, swollen nodes can cause visible puffiness.

The important part is knowing which one applies to us. For example, if it’s mostly skin laxity, exercise alone might not be enough. And if it’s axillary breast tissue, only surgical removal works. That’s why many people try self-assessment first, then consult a professional if results are slow.

Can You Get Rid of Armpit Fat Naturally?

Yes, in some cases- but not always completely. If it’s primarily extra fat, then a mix of overall fat loss and targeted strengthening can help reduce it. That means eating in a calorie deficit and staying active.

However, we can’t “spot reduce” fat from just one place. So, while chest and arm exercises help tone the area, they won’t magically burn only armpit fat. On the other hand, if the bulge is loose skin or axillary breast tissue, lifestyle changes alone won’t remove it.

In short, natural methods are worth trying, but if results feel stuck, professional options might be the next step.

Best Exercises for Reducing Armpit Fat

While exercise can’t target fat in one exact spot, strengthening nearby muscles can create a firmer, more toned appearance. Here are some we’ve seen help:

1. Push-Ups– Strengthens the chest, shoulders, and triceps. Keep elbows slightly tucked to engage the area near the armpits.
2. Chest Press (Dumbbells or Machine)– Builds chest muscles, which can reduce the look of sagging skin.
3. Plank to Shoulder Tap– Works the core and shoulders while stabilizing the upper body.
4. Lateral Raises– Targets shoulder muscles, improving arm and armpit definition.
5. Chest Flys– Opens the chest and tones the pectoral muscles.
6. Pull-Ups or Assisted Pull-Ups– Strengthens the back and underarm area.

It’s not just about strength training, though. Cardio plays a big role in overall fat loss. Even something as simple as brisk walking or cycling can help over time.

One thing to keep in mind- muscles adapt quickly. Switching up routines every few weeks keeps progress going. And no, you don’t have to spend hours daily. Even 20-30 minutes, three to four times a week, can make a visible difference when combined with a balanced diet.

Non-Surgical Treatment Options

If exercise and diet aren’t giving the results we want, there are non-invasive treatments that can help smooth and slim the armpit area.

Some common options include:

• Cryolipolysis (Fat Freezing)– Freezes fat cells so the body gradually removes them.
• Radiofrequency Skin Tightening– Uses heat to stimulate collagen and improve skin firmness.
• Laser Lipolysis– Breaks down fat cells using laser energy.

These treatments can be great for mild to moderate fat or skin laxity. They usually involve little to no downtime, and results improve over weeks as the body processes fat naturally.

Surgical Solutions for Armpit Fat

When the bulge is more stubborn- especially if it’s axillary breast tissue or large fat deposits- surgery can be the most effective route.

The main surgical methods are:

• Liposuction– Removes fat directly through small incisions.
• Excision Surgery– Removes excess skin or tissue, often for axillary breast tissue.
• Combination Procedures– Sometimes both fat and skin need addressing for a smooth contour.

Recovery depends on the procedure. Liposuction often allows a quicker return to daily life, while excision may require a longer healing period. Scars are usually minimal and placed discreetly.

If we’re thinking about going surgical, it’s worth first speaking to a qualified specialist. They can assess whether we’re a good candidate, discuss realistic results, and plan the safest approach. We always recommend starting with a consultation- we can book an appointment and evaluate the right solution together.

Armpit Fat vs. Axillary Breast Tissue- Key Differences

It’s easy to confuse the two. Armpit fat is purely fatty tissue and responds somewhat to weight loss and exercise. Axillary breast tissue, on the other hand, is an extension of breast tissue that develops during fetal growth.

Fat feels softer and may fluctuate with body weight changes. Axillary breast tissue feels firmer, sometimes tender, and may swell during hormonal cycles.

This distinction matters because axillary breast tissue doesn’t go away without surgery. So, if workouts and diet changes aren’t helping, it might be worth checking with a doctor to confirm what’s causing the bulge.
