How to Get Rid of Armpit Fat? 6 Exercises + Plan

The best exercises to get rid of armpit fat are strength moves for your chest, back, shoulders and arms, like push-ups, rows and presses, paired with overall fat loss.

One honest caveat first: no exercise burns fat from just one spot. The goal is to build firm muscle around the area while your body loses fat as a whole.

Do that consistently and the area looks tighter and more defined.

Here's what works, what doesn't, and a simple plan you can start today.

What Is Armpit Fat? (And Is It Always Fat?)

Armpit fat is the soft fullness at the front or side of the armpit, usually near where a bra band, strap or shirt seam sits. It's very common, it shows up in every body type, and it's normally harmless.

But not every bulge is fat. These are the usual causes:

Genetics decides much of where your body stores fat, so some people carry a little near the armpit even at a lean weight.

Accessory breast tissue is real breast tissue, which is why it can respond to hormones and why a doctor should check anything that's new or changing.

Can Exercise Get Rid of Armpit Fat?

Not from that spot alone. A 2022 systematic review and meta-analysis of studies comparing a trained limb with an untrained one found that training a muscle did not reduce the fat sitting over it.

Fat comes off across your whole body, and your genetics largely decide where it leaves first and last.

For balance: one 2023 randomized trial in overweight men found that abdominal endurance exercise used more local fat than treadmill running. (Brobakken et al.) That was a single study of one exercise in one group, so it doesn't change the practical advice here.

What exercise can do for the armpit area:

1. Build the muscle around it. Your pecs, lats, front shoulders and triceps frame the armpit. Stronger, firmer muscle changes the shape of the area.
2. Support overall fat loss. A 2025 meta-analysis supports combining resistance and aerobic training for reducing fat mass. (PMC)
3. Improve posture. Strong upper-back muscles help you stand taller, which changes how the area sits.

That's the realistic version of "getting rid of armpit fat": muscle building plus whole-body fat loss, not a magic move.

Best Exercises to Get Rid of Armpit Fat (6 Moves)

Use a weight that lets you finish every rep with clean form and stop 1 to 2 reps before failure. Rest 60 to 90 seconds between sets. If you're brand new to training, start with the easier options.

1. Push-Up

The most popular pick for good reason. Push-ups train your chest, front shoulders, triceps and core together, and you can do them anywhere.

How to do it:

1. Start in a plank with hands slightly wider than your shoulders.
2. Keep your body in one straight line from head to heels.
3. Lower your chest toward the floor with elbows at about 45 degrees.
4. Press back up until your arms are straight.

Sets and reps: 3 sets of 8 to 15. Easier: hands on a bench or counter (incline) or on your knees. Harder: slow the lowering phase to 3 seconds, or elevate your feet.

For a triceps-heavy version, try the close grip push-up, or browse more bodyweight arm workouts.

2. Dumbbell Chest Press (or Floor Press)

A heavier pressing move that builds the pecs and triceps and lets you progress with weight over time.

How to do it:

1. Lie on a bench or the floor with a dumbbell in each hand over your chest.
2. Lower the weights until your upper arms reach the bench or floor.
3. Press up and slightly together until your arms are straight.

Sets and reps: 3 sets of 8 to 12.

3. Chest Fly

The fly stretches and squeezes the chest muscle that forms the front wall of the armpit.

How to do it:

1. Lie on your back holding light dumbbells above your chest, palms facing each other.
2. With a soft bend in your elbows, open your arms wide until you feel a stretch across your chest.
3. Bring the weights back together in a hugging motion.

Sets and reps: 3 sets of 10 to 12 with a light weight. Keep it controlled, because flyes load the shoulder. Cable option: see our cable chest exercises and cable arm workouts.

4. One-Arm Dumbbell Row

Your lats form the back wall of the armpit, and rows build them while improving posture. Most armpit fat workouts skip the back. This one shouldn't.

How to do it:

1. Place one knee and one hand on a bench, back flat.
2. Hold a dumbbell in the other hand, arm hanging straight.
3. Pull the weight toward your hip, squeezing your shoulder blade back.
4. Lower slowly.

Sets and reps: 3 sets of 10 to 12 per side. More pulling ideas: best pull exercises and kettlebell gorilla rows.

5. Dumbbell Overhead Press

Builds the shoulders and triceps and trains you to brace your core and stand tall under load.

How to do it:

1. Stand with dumbbells at shoulder height, core tight.
2. Press straight overhead until your arms are extended.
3. Lower under control.

Sets and reps: 3 sets of 8 to 10. Variations are in our dumbbell shoulder exercises.

6. Bench Tricep Dip (or Close-Grip Push-Up)

Dips target the back of the upper arm, the part many people mean when they say "underarm fat".

How to do it:

1. Sit on the edge of a bench with hands beside your hips.
2. Slide your hips off the edge with your legs bent or straight.
3. Lower until your elbows reach about 90 degrees.
4. Press back up.

Sets and reps: 3 sets of 10 to 15. Shoulder bothers you on dips? Swap in close-grip push-ups. For more options, see our guide to the best triceps compound exercises.

Armpit Fat Workout (A Simple Weekly Plan)

You don't need to train every day. Two or three strength sessions plus some cardio is enough for most people.

Progress slowly. When you can complete all sets and reps with good form, add a little weight or a few reps. To balance the plan, add a couple of sets of curls using ideas from our best bicep exercises.

How to Get Rid of Armpit Fat

Exercise is only one piece. These three matter just as much.

Overall fat loss

Since fat comes off the whole body, the basics decide how fast the area changes:

• A modest, sustainable calorie deficit. Crash diets backfire. Slow and steady is easier to keep up.
• Enough protein and whole foods to support the muscle you're building.
• Sleep and daily steps. Both are underrated for body composition.
• Two cardio sessions a week. Walking, cycling or light intervals all count.

Posture

Rounded shoulders push soft tissue forward and bunch it at the front of the armpit. Add these 2 to 3 times a week:

• Wall slides: 2 sets of 10
• Band pull-aparts: 2 sets of 15
• Doorway chest stretch: 2 holds of 30 seconds

A stronger core also helps you stand tall. Try our calisthenics core exercises.

Bra and clothing fit

If the bulge sits right at the band or strap line, fit may be the cause. A band that rides up or cups that are too small can push soft tissue outward. A professional bra fitting is a cheap, fast thing to try before changing anything else.

Armpit Fat in Men vs. Women

The training advice is the same for everyone: build the chest and back, lose fat overall, and keep posture strong.

• Women more often notice fullness near the bra line, and hormonal changes through puberty, periods, pregnancy and menopause can affect it.
• Men may see fullness from fat, but also from well-developed chest and lat muscle, which is a good sign, not a problem.

In both, a firm lump, a one-sided change or any new swelling is worth a doctor visit.

How Long Does It Take to Lose Armpit Fat?

It varies a lot, and anyone promising a set number of days is guessing. A reasonable expectation:

• 2 to 4 weeks: you feel stronger, form gets better, posture starts to improve.
• 8 to 12 weeks: muscle tone in the chest, back and arms is usually more visible with consistent training.
• Fat change: depends on your overall fat loss and genetics. Some people see the area change early, others later.

Take photos from the same angle every 3 to 4 weeks. The mirror changes slowly, and photos show progress you'd otherwise miss.

FAQ: Exercises to Get Rid of Armpit Fat

Can exercise get rid of armpit fat?

Not from that spot alone. Research reviews find that training one area doesn't burn fat from that area, so fat comes off across your whole body. Strength training firms the muscles around the armpit, and overall fat loss through food, activity and sleep reduces the fat itself.

What is the best exercise for armpit fat?

Push-ups are the most popular pick because they work your chest, shoulders, triceps and core together. Pair them with rows, chest presses, flyes and overhead presses for balanced upper-body strength, and add walking or cardio for overall fat loss.

Do push-ups get rid of armpit fat?

Push-ups help build the muscles around the area and burn calories, but they can't remove fat from the armpit specifically. Treat them as one part of a plan that includes rows, pressing, cardio and nutrition.

How long does it take to lose armpit fat?

Strength usually improves within a few weeks, and muscle tone often shows after 8 to 12 weeks of steady training. How much the fat changes depends on your overall fat loss and genetics, so progress varies from person to person.

Why do I have armpit fat even though I'm thin?

Fat distribution is largely genetic, so some people store a little fat near the armpit at a low body weight. Tight clothing or a poorly fitting bra can push soft tissue outward, and sometimes the fullness is accessory breast tissue rather than fat.

Is armpit fat the same as breast tissue?

No. Armpit fat is fat tissue. Axillary (accessory) breast tissue is real breast tissue that can extend into the armpit and may swell with hormonal changes like periods or pregnancy. It often feels firmer than fat. A doctor can tell them apart, and any new lump should be checked.

Can men get rid of armpit fat?

Yes, the same approach applies. Men can have fullness from fat or from developed chest and lat muscle. Strength training for the chest and back, overall fat loss and a doctor visit for any new lump or one-sided swelling cover the basics.

Can a bra cause armpit fat?

A band that's too tight or cups that are the wrong size can push soft tissue over the band or strap line, making existing tissue look more prominent. A professional fitting often helps.
