Do bicep curls burn fat? The short answer is no, bicep curls alone won’t burn much fat. A set of bicep curls burns about 5 to 10 calories. That’s roughly the same as one small bite of a banana. If you’re doing curls hoping to melt away belly fat or arm fat, you’re going to be disappointed.
But here’s the thing. Bicep curls still have a place in a fat loss program. They build muscle and muscle does burn more calories than fat, even when you’re sitting on the couch doing nothing. The real question isn’t whether bicep curls burn fat. It’s how exercise fits into the bigger picture of losing weight.
Why don’t bicep curls burn much fat?
Your biceps are tiny muscles. They’re about the size of a small lemon. When you curl a dumbbell, you’re only working this one small muscle group. Compare that to a squat or deadlift where you use your quads, glutes, hamstrings, core and back all at once. More muscle working means more calories burned.
Research shows that exercises using large muscle groups burn far more calories than isolation exercises like curls. A 2012 study found that compound movements using multiple joints burned 50% more calories than single joint exercises at the same effort level.
The math is simple. Your biceps make up less than 2% of your total muscle mass. Your legs and back make up over 60%. When you want to burn calories through exercise, use the big muscles.
How many calories does a bicep curl actually burn?
Let’s break down the numbers. A 75kg person doing moderate intensity bicep curls for 10 minutes burns about 30 to 40 calories. That’s 3 to 4 calories per minute. A single set of 12 curls takes about 30 to 45 seconds, so you’re looking at roughly 2 to 3 calories per set.
To put this in perspective, here’s what burns more calories in the same time
- Squats burn about 8 to 10 calories per minute
- Deadlifts burn about 9 to 12 calories per minute
- Walking briskly burns about 5 to 6 calories per minute
- Running burns about 10 to 15 calories per minute
A single Tim Tam has about 95 calories. You’d need to do roughly 30 sets of bicep curls to burn off one biscuit. That’s a lot of curling for not much return.

Does building muscle from curls help with fat loss?
Yes, and this is where things get interesting. One pound of muscle burns about 6 calories per day at rest. One pound of fat burns about 2 calories. That’s a 3x difference.
So if you build 2kg of muscle over a year of training, that’s an extra 26 calories burned every single day just by existing. Over a year, that adds up to 9,500 extra calories burned, or roughly 1.2kg of fat.
Building muscle also changes how your body looks at the same weight. Two people who weigh 75kg can look completely different. The one with more muscle and less fat will look leaner, even though the scale shows the same number.
Bicep curls do build muscle, and that muscle does help with fat loss over time. Just don’t expect the curls themselves to burn significant calories during your workout.
What’s the best way to burn fat with exercise?
Fat loss comes down to one thing. You need to burn more calories than you eat. This is called a calorie deficit. Exercise can help create this deficit, but your diet does most of the heavy lifting.
Research from meta analyses on exercise and weight loss shows something interesting. When people burn 2,000 calories through cardio per week, they lose less than half the fat they should on paper. Why? Because they move less during the rest of the day and often eat more to compensate.
The best approach combines these strategies
- Resistance training to build or keep muscle mass
- Walking 7,000 to 12,000 steps per day
- Eating in a moderate calorie deficit
- Getting enough protein (about 1.6 to 2g per kg of body weight)
Studies show that over 70% of people who lose weight and keep it off exercise regularly. Less than 30% of people who regain weight were exercising. Exercise matters for long term success, even if it doesn’t burn as many calories as people think.
Should you skip bicep curls if you want to lose fat?
No. Bicep curls still belong in your program. They build arm muscle and that muscle keeps your metabolism slightly higher. They also make you stronger for everyday activities like carrying groceries or picking up kids.
The mistake is thinking curls will directly burn fat off your arms. That’s called spot reduction, and it doesn’t work. You can’t choose where your body burns fat from. When you’re in a calorie deficit, your body pulls fat from wherever it wants, usually the last place you gained it.
A solid fat loss workout includes both compound lifts and isolation exercises like curls. Do your squats, deadlifts, rows and presses first when you have the most energy. Then add curls, tricep extensions and lateral raises at the end. This gives you the calorie burn from big movements plus the muscle building benefits of isolation work.
How much cardio vs strength training for fat loss?
Research comparing high intensity interval training to steady state cardio found no difference in fat loss when total work was equal. The type of cardio matters less than being consistent with it.
For fat loss, aim for this weekly setup
- 3 to 4 strength training sessions lasting 45 to 60 minutes
- 7,000 to 12,000 steps per day from walking
- Optional 2 to 3 cardio sessions of 20 to 30 minutes
Walking beats intense cardio for most people because it doesn’t make you hungry afterwards and it doesn’t tire you out. A highly active person can burn up to 2,000 extra calories per day just from daily movement like walking, typing and doing chores. This is called NEAT (non exercise activity thermogenesis) and it often matters more than your gym workout.
What about arm fat specifically?
Many people do curls hoping to tone their arms or get rid of arm fat. Again, spot reduction doesn’t work. The fat on your arms will decrease when your overall body fat decreases, not from doing more arm exercises.
If your arms look soft or jiggly, two things need to happen
- Reduce your overall body fat through a calorie deficit
- Build muscle in your arms through exercises like curls
When you lower your body fat and increase your arm muscle, your arms will look more toned and defined. But the toning comes from the combination of less fat and more muscle, not from curls alone.
Women sometimes worry that arm exercises will make their arms bulky. This rarely happens. Women have much lower testosterone than men, making it very hard to build large muscles. What usually happens is arms get more defined and shapely, not bulky.
What exercises burn the most fat?
If calorie burn is your goal, choose exercises that use the most muscle
- Deadlifts use your entire back, glutes, hamstrings and grip
- Squats work your quads, glutes, hamstrings and core
- Rows hit your back, biceps and rear shoulders
- Bench press uses chest, shoulders and triceps
- Lunges target legs and glutes while challenging balance
These compound movements burn 3 to 5 times more calories per minute than bicep curls. They also trigger a bigger hormonal response, which helps with muscle building and recovery.
A good rule is to start your workout with 3 to 4 compound exercises. Then finish with 2 to 3 isolation exercises like curls. This way you get the best of both worlds.
FAQ
Will doing 100 bicep curls a day burn fat?
No, 100 bicep curls burns about 20 to 30 calories total. That’s less than one slice of bread. Your time would be better spent on compound exercises or walking.
Can I tone my arms with just bicep curls?
Partially. Curls build the bicep muscle, but your arms also have triceps (back of arm), shoulders and forearm muscles. You need exercises for all these muscles plus a calorie deficit to see definition.
How long does it take to see results from bicep curls?
Most people notice strength gains within 2 to 4 weeks. Visual changes take longer, usually 8 to 12 weeks of consistent training combined with proper nutrition.
Should I do bicep curls every day?
No. Muscles need 48 to 72 hours to recover and grow. Training biceps 2 to 3 times per week with at least one rest day between sessions works better than daily training.
What weight should I use for bicep curls?
Use a weight that lets you do 8 to 15 reps with good form. The last 2 to 3 reps should feel hard but not impossible. For most beginners, this is 5 to 10kg dumbbells.
Are bicep curls a waste of time?
No. They build arm strength and muscle. They just shouldn’t be your main exercise if fat loss is the goal. Include them as part of a complete program that emphasizes compound movements.
Do bicep curls build muscle or just tone?
Curls build muscle. Toning is just a word for building a bit of muscle while losing some fat. There’s no special toning mode. Your muscles either grow, shrink or stay the same.
How many sets of bicep curls should I do per week?
Research suggests 10 to 20 sets per muscle group per week for muscle growth. For biceps, 6 to 10 direct sets plus the indirect work from rows and pullups is usually enough.
Is it better to do heavy or light bicep curls?
Both work for building muscle. Studies show rep ranges from 5 to 30 can build muscle as long as you push close to failure. Mix it up with heavier weights and lower reps some days, lighter weights and higher reps other days.
Why aren’t my arms getting smaller even though I do curls?
Fat loss requires a calorie deficit. If you’re not losing fat from your arms, you’re probably eating too many calories. Track your food for a week to see where you stand.
While isolation exercises have their place, combining them with cardio like slow walking for belly fat reduction creates better overall results. Nutrition also matters significantly—learn what to eat to avoid bloating and keep your midsection looking lean. Work with a Southbank personal trainer to build an effective fat-burning routine.
