Lift your arm, give it a wave, and watch the back of it keep moving after you stop.
That loose, flapping skin is what most people call bat wings, and it is one of the most common reasons people cover their arms in long sleeves and skip the tank top.
The good news: the right training tightens that area up. The honest part most articles skip: there is no single exercise that melts fat off one spot.
The best arm exercises for bat wings work by building the muscle under the skin while you lower body fat overall. Do both and the back of your arms gets firmer, leaner, and far more defined.
Here is exactly what causes bat wing arms, what actually works, and the 10 best moves to get rid of them.
What Causes Bat Wings on the Arms
Bat wings usually come from a mix of three things, and knowing which one you are dealing with changes your plan.
Excess fat in the upper arms
Carrying extra body fat often shows up on the back of the arms, making them look full and soft even if you train.
Undertrained triceps
The triceps make up about two-thirds of your upper arm. When they are weak and flat, there is no muscle pushing against the skin, so the area looks loose.
Loose skin
After major weight loss or with age, skin can lose its snap. Exercise firms the muscle underneath and improves the look, but very loose skin may not fully tighten without cosmetic help.
Best Arm Exercises for Bat Wings
These are the best arm exercises to get rid of bat wings, built around the triceps with supporting moves for balance and posture.
You can do most of them at home with light dumbbells or just your body weight.
1. Tricep Dips
Tricep dips hit the back of the upper arm directly, the exact spot where bat wings form. They need nothing but a sturdy chair or bench.
- Sit on the edge of a bench, hands beside your hips, fingers pointing forward.
- Slide your hips off the edge with legs extended in front.
- Bend your elbows to lower your body until they reach about 90 degrees.
- Keep your elbows pointing back, not flaring out.
- Push back up to the start. Aim for 3 sets of 10 to 15 reps.
2. Diamond Push-Ups
This at-home bat wings exercise puts maximum load on the triceps by bringing your hands together under your chest.
- Start in a plank, hands close so your thumbs and index fingers form a diamond.
- Keep your body in a straight line and core tight.
- Lower your chest toward your hands.
- Press back up, squeezing the back of your arms. Do 3 sets of 8 to 12 reps. Drop to your knees if needed.
3. Overhead Tricep Extension
One of the best moves to tone flabby arms, the overhead extension stretches and works the triceps through a full range.
- Hold one dumbbell with both hands, arms extended overhead.
- Keep your elbows close to your head as you lower the weight behind you.
- Stop when your forearms pass parallel, then press back up.
- Perform 3 sets of 12 to 15 reps.
4. Tricep Kickbacks
Kickbacks isolate the triceps and train each arm on its own, which fixes side-to-side imbalances that make arms look uneven.
- Hold a dumbbell in your right hand, hinge forward with a flat back.
- Keep your upper arm pinned to your side.
- Extend your arm straight back and squeeze the tricep.
- Lower under control, then switch sides. Do 3 sets of 12 reps per arm.
5. Skull Crushers
A staple tricep exercise for bat wings, skull crushers load the muscle hard while you lie down, taking your shoulders out of the movement.
- Lie on a bench or floor holding dumbbells over your chest, arms straight.
- Bend at the elbows to lower the weights toward your forehead.
- Keep your upper arms still and vertical.
- Press back to the top. Do 3 sets of 10 to 12 reps.
Bat Wing Exercises
Here are a few more options:
6. Close-Grip Push-Ups
A scalable bodyweight move that builds the triceps and chest together, great for getting rid of bat wings at home.
- Set up in a plank with hands narrower than shoulder width.
- Lower your chest while keeping your elbows tucked close to your ribs.
- Press back up. Do 3 sets to a challenging rep count.
7. Resistance Band Pull-Aparts
This one targets the back of the shoulders and improves posture, which instantly makes flabby arms look tighter and more lifted.
- Hold a resistance band in front of you at chest height, arms straight.
- Pull the band apart by squeezing your shoulder blades together.
- Return slowly under control. Do 3 sets of 15 reps.
8. Lat Pulldown
Building the back widens your frame and balances the upper body, making the arms look leaner by comparison. Use a machine or a band anchored overhead.
- Grab the bar with a wide grip, palms facing away.
- Pull it down toward your upper chest, driving your elbows down and back.
- Control the bar back up. Do 3 sets of 10 to 15 reps.
9. Hammer Curls
Curls balance the front of the arm so your toned triceps are not fighting flat biceps. Hammer curls also build the forearm for a stronger, fuller look.
- Hold a dumbbell in each hand, palms facing your body.
- Keep your upper arms still and curl toward your shoulders.
- Squeeze at the top, then lower slowly. Do 3 sets of 12 reps.
10. Arm Circles
A no-equipment finisher that fatigues the shoulders and arms and works well as a warm-up too.
- Stand with arms extended out to your sides at shoulder height.
- Make small controlled circles forward for 30 seconds.
- Reverse direction for another 30 seconds. Repeat for 3 rounds.

Frequently Asked Questions
What causes bat wings on the arms?
A combination of excess upper-arm fat, weak or undertrained triceps, and sometimes loose skin from weight loss or aging.
Can you get rid of bat wings with exercise?
In most cases, yes. Building the triceps and losing overall body fat tightens the area. If the issue is mainly loose skin, exercise helps the look but may not fully remove it.
How long does it take to get rid of bat wings?
With consistent training, a calorie deficit, and regular cardio, most people see a noticeable change in 8 to 12 weeks, depending on starting point and body fat.
Do I need weights to get rid of bat wings?
No. Bodyweight moves like tricep dips, diamond push-ups, and close-grip push-ups work well. Light dumbbells or bands speed up the results.
Can you spot-reduce arm fat?
No. Fat loss happens across the whole body. You build the arm muscle directly, but the fat comes off everywhere at once through diet and cardio.
Final Verdict
It's clear that having defined arms is not an easy task. However, with the right exercises and proper dedication, you too can achieve the toned arms you've always wanted.
With consistency, you'll soon have lean and toned arms ready to flaunt.
