Ever stood in the gym, dumbbells in hand, wondering which curl will give you those head-turning arms?
You’re not alone! Arm workouts are a favorite for fitness buffs, from beginners dreaming of bigger biceps to athletes chasing functional strength. Two exercises often steal the spotlight: the classic bicep curl and the lesser-known Zottman curl. Both promise stronger, more defined arms, but which one’s right for you?
In this post, we’ll break down the differences, benefits, and best uses of these arm-building powerhouses. Whether you’re aiming for sleeve-busting biceps or forearms that grip like a vice, we’ve got you covered with practical tips, expert insights, and a touch of science to guide your next workout.
What Is a Bicep Curl?
The bicep curl is the rockstar of arm exercises, a go-to move for anyone looking to sculpt their upper arms. It’s simple, effective, and a staple in gyms worldwide.
When you do a bicep curl, you’re mainly targeting the biceps brachii, the muscle that gives your arms that iconic “pop.” But it also works the brachialis (under the biceps) and brachioradialis (a forearm muscle) to a lesser extent.
Types of Bicep Curls
You’ve got options with bicep curls, which makes them versatile:
- Dumbbell Bicep Curl: Great for unilateral training to balance both arms.
- Barbell Bicep Curl: Allows heavier weights for maximum strength gains.
- EZ-Bar Curl: Easier on the wrists, perfect for those with joint issues.
- Cable Bicep Curl: Constant tension for a unique burn.
- Preacher Curl: Isolates the biceps by locking your arms in place.
- Concentration Curl: Hyper-focuses on one arm for peak contraction.
Why Do Bicep Curls?
Bicep curls are a must for anyone chasing bigger, stronger arms. According to a 2018 study in the Journal of Strength and Conditioning Research, bicep curls activate the biceps brachii more than most other isolation exercises, making them a top pick for hypertrophy (muscle growth).
They also boost your pulling strength, which helps with compound lifts like deadlifts or rows. Plus, let’s be honest—who doesn’t want arms that look great in a t-shirt?
Common Mistakes to Avoid
It’s easy to mess up bicep curls if you’re not careful:
- Swinging the Weights: Using momentum cheats your muscles. Keep it slow and controlled.
- Lifting Too Heavy: Ego-lifting leads to bad form and injuries. Choose a weight you can handle.
- Moving Elbows: Your elbows should stay tucked by your sides, not flaring out.
Equipment Needed: Dumbbells, a barbell, an EZ-bar, or a cable machine.
Testimonial: “Bicep curls transformed my arms in just 12 weeks,” says Sarah, a 28-year-old fitness enthusiast. “I started with light dumbbells and focused on form, and now my arms are stronger and more defined than ever!”
What Is a Zottman Curl?
The Zottman curl is like the bicep curl’s cooler, more versatile cousin. Invented by 19th-century strongman George Zottman, this exercise combines the best of both worlds: it builds your biceps and your forearms in one move.
During the lift, you use a supinated grip (palms up) to target the biceps, then rotate to a pronated grip (palms down) to hit the forearms on the way down.
Muscles Worked
Zottman curls are a two-for-one deal:
- Concentric Phase (lifting): Hits the biceps brachii.
- Eccentric Phase (lowering): Engages the brachioradialis and forearm flexors/extensors.
Why Do Zottman Curls?
Zottman curls are a game-changer for balanced arm development. A 2020 study in Sports Medicine found that exercises with eccentric loading (like the Zottman curl’s lowering phase) can reduce injury risk by strengthening muscles under tension.
They’re also a favorite for athletes like climbers or wrestlers who need grip strength. Plus, they add variety to your routine, keeping your workouts fresh and your muscles guessing.
Common Mistakes to Avoid
Zottman curls require a bit more finesse:
- Rushing the Lowering Phase: Slow down to maximize forearm gains.
- Incorrect Wrist Position: Keep wrists straight to avoid strain.
- Using Too Much Weight: The forearm portion limits how heavy you can go, so don’t overdo it.
Equipment Needed: Just a pair of dumbbells.
Testimonial: “I added Zottman curls to my routine, and my grip strength went through the roof,” says Mike, a 35-year-old rock climber. “They’re tough, but my forearms are way stronger for climbing now.”
Step-by-Step: How to Do Each Curl
Bicep Curl Technique
- Stand tall with a dumbbell in each hand, palms facing up (supinated grip).
- Keep your elbows close to your sides and shoulders relaxed.
- Curl the weights up toward your shoulders, squeezing your biceps at the top.
- Lower the weights slowly back to the starting position.
- Exhale as you lift, inhale as you lower.
Zottman Curl Technique
- Stand with a dumbbell in each hand, palms facing up.
- Curl the weights up like a regular bicep curl, squeezing at the top.
- At the top, rotate your wrists so palms face down (pronated grip).
- Slowly lower the weights, keeping control to work the forearms.
- Rotate wrists back to starting position and repeat.
- Exhale on the lift, inhale on the lower.
Pro Tip: Record yourself or ask a trainer to check your form. Proper technique is everything!

Key Differences Between Zottman and Bicep Curls
Here’s how these two stack up:
Grip and Muscle Focus
- Bicep curls use a supinated grip to zero in on the biceps.
- Zottman curls switch grips, hitting both biceps and forearms.
Range of Motion
- Bicep curls follow a straightforward up-and-down path.
- Zottman curls add wrist rotation for extra muscle engagement.
Complexity
- Bicep curls are beginner-friendly and easy to master.
- Zottman curls require more coordination due to the grip change.
Training Goals
- Bicep curls are king for building big biceps and aesthetics.
- Zottman curls shine for functional strength and balanced arms.
| Exercise | Key Focus | Difficulty Level | Benefit |
|---|---|---|---|
| Bicep Curls | Biceps | Easy | Builds size and improves aesthetics |
| Zottman Curls | Biceps and Forearms | Moderate | Enhances functional strength and balance |
Benefits and Drawbacks of Bicep Curls
Pros
- Super easy to learn, perfect for newbies.
- Maximizes bicep growth for that chiseled look.
- Tons of variations to keep things interesting.
Cons
- Doesn’t do much for forearms.
- Easy to plateau without mixing up reps or weights.
Benefits and Drawbacks of Zottman Curl
Pros
- Builds biceps and forearms for all-around arm strength.
- Boosts grip for sports like tennis or grappling.
- Eccentric focus helps prevent injuries.
Cons
- Trickier to get the form right.
- You’ll need lighter weights because of the forearm work.
When to Use Each Exercise
Bicep Curls
- Perfect for beginners who want to focus on bicep size.
- Ideal for bodybuilders chasing that peak bicep look.
- Great for heavy, high-volume sessions to push muscle growth.
Zottman Curls
- Awesome for athletes needing grip and forearm power (think CrossFit or MMA).
- Helps break through plateaus by adding variety.
- Supports functional fitness and injury prevention.
Mixing Both: Try doing bicep curls early in your workout for heavy lifting, then finish with Zottman curls for forearm focus.
