Estimate calories burned from bicep curls based on your body weight, weight lifted per curl, total curls, and optional curl style or pace.
How Many Calories Do Bicep Curls Burn?
Bicep curls are a low-calorie isolation lift because the movement is driven mainly by the elbow flexors rather than the hips, chest, or back. In most workouts, 20 to 40 total curls burn only a few calories, while 60 to 100 curls usually land in the teens or low 30s depending on body weight and the load used.
| Body Weight | Load Per Curl | Total Curls | Calories Burned |
|---|---|---|---|
| 130 lb | 15 lb | 60 | 13.7 |
| 150 lb | 25 lb | 60 | 18.3 |
| 180 lb | 35 lb | 60 | 23.7 |
| 200 lb | 45 lb | 60 | 28.3 |
Bicep Curl Calorie Formula
The calculator uses a simple rep-based lifting formula:
Calories Burned = Total Curls × (0.0025 × Body Weight in kg + 0.012 × Load in kg) × Style Factor × Pace Factor
In the Basic version, style and pace stay at 1.00. In the Advanced version, curl style and rep pace can raise or lower the total slightly.
| Advanced Setting | Factor | Effect |
|---|---|---|
| Standard Curl | 1.00 | Baseline |
| EZ Bar / Barbell Curl | 1.05 | Slight increase |
| Hammer Curl | 1.08 | Small increase |
| Preacher / Concentration Curl | 0.90 | Slight decrease |
| Fast Pace | 0.92 | Lower calories per curl |
| Normal Pace | 1.00 | Baseline |
| Controlled Pace | 1.10 | Higher calories per curl |
What Changes the Number Most?
- Total curls: doubling your curls nearly doubles calories burned.
- Weight lifted: moving from a 15 lb dumbbell to a 35 lb dumbbell materially raises calories per rep.
- Body weight: larger lifters burn more because more mass is stabilized through the set.
- Curl style and pace: hammer curls and slower controlled reps push the total slightly higher.
| 150 lb Person | 20 Curls | 40 Curls | 60 Curls | 100 Curls |
|---|---|---|---|---|
| 15 lb Curl | 5.0 | 10.1 | 15.1 | 25.2 |
| 25 lb Curl | 6.1 | 12.2 | 18.3 | 30.6 |
| 35 lb Curl | 7.2 | 14.4 | 21.6 | 36.1 |
What Muscles Do Bicep Curls Work?
Bicep curls mainly train the biceps brachii, with strong assistance from the brachialis and brachioradialis. Standard supinated curls emphasize the biceps most, hammer curls shift more work to the brachioradialis, and preacher-style curls reduce body swing so the elbow flexors do more of the work. Because these are relatively small muscles, curls build the arms well but do not burn as many calories as rows, presses, squats, or deadlifts.
Frequently Asked Questions
Do alternating dumbbell curls count as 10 or 20 curls?
Count each arm movement as 1 curl. If you do 10 reps on the left and 10 on the right, enter 20 total curls.
Do hammer curls burn more calories than standard curls?
Usually yes. Hammer curls often let you handle slightly more load and involve more brachioradialis, so the calorie total is a little higher.
Are barbell curls higher than dumbbell curls?
Often slightly higher, mainly because total load is usually greater with an EZ bar or barbell.
Are bicep curls a good calorie-burning exercise?
They are better for building arm strength and size than for maximizing calorie burn. Compound lifts and cardio move the calorie total up much faster.
How can I burn more calories during curls?
Do more total curls, use a heavier weight you can control, shorten rest periods, or choose hammer or EZ bar variations at a controlled pace.
