Could the Zottman Curl Be the Ultimate Bicep and Forearm Exercise?
When it comes to building an impressive physique, most lifters zero in on the headline muscle groups — chest, lats, biceps, legs (hopefully). That’s only natural. Classic split training programs often dedicate entire days to these major body parts. But if your goal is to craft a complete, balanced, and competition-ready physique, you can’t ignore the finer details.
True muscular symmetry comes from training every inch of your arms — and that includes the often-overlooked forearms. Our team at Generation Iron is going to break down the Zottman Curl, an exercise that is guaranteed to blast your forearms.
Why Forearm Development Matters
Strong, muscular forearms don’t just look impressive — they also play a critical role in overall upper-body performance. Your grip strength is directly tied to how much weight you can pull on deadlifts, rows, and pull-ups, and it heavily influences your endurance during high-rep sets. Neglecting forearm training can become a limiting factor for progress in other lifts.
The trouble is, forearms are notoriously stubborn. They can be difficult to grow because they’re heavily used in daily activities and tend to recover quickly from training stress. That means you need targeted, strategic movements that specifically overload the forearm muscles.
Enter the Zottman Curl
One of the best old-school methods for building forearms and biceps at the same time is the Zottman curl — a movement named after legendary 1890s strongman George Zottman, known for his Herculean feats of strength and famously thick forearms.
The Zottman curl combines the benefits of a standard dumbbell curl and a reverse curl into one seamless motion. It allows you to overload the biceps on the way up (concentric phase) and then place heavy tension on the brachioradialis and forearm extensors on the way down (eccentric phase).
How to Perform the Zottman Curl
- Start Position: Stand tall holding a dumbbell in each hand with a supinated (palms-up) grip.
- Curl Up: Perform a traditional bicep curl, keeping your elbows tucked and upper arms stationary.
- Rotate at the Top: Once you reach the top of the curl, rotate your wrists 180° so your palms face downward (pronated grip).
- Lower Slowly: Lower the dumbbells under control in this pronated position, emphasizing a slow eccentric to fully engage your forearms.
- Reset: Rotate your wrists back to palms-up and repeat for 8–12 reps.
Pro tip: Use moderate weight and strict form. Focus on time under tension rather than going heavy. This will maximize both bicep and forearm activation.
Benefits of the Zottman Curl
- Builds bicep peak and forearm thickness simultaneously
- Improves grip strength and pulling power
- Adds variety to your arm workouts
- Reduces strength imbalances between biceps and forearms
- Time-efficient for athletes with busy training splits
Adding Zottman Curls to Your Workout
For best results, add Zottman curls toward the end of your arm day after your heavy compound lifts. Start with 3 sets of 10–12 reps. As your forearms adapt, increase the time under tension by slowing the lowering phase to 3–4 seconds per rep.
They also work well as part of a superset with traditional curls, hammer curls, or reverse curls to fully exhaust the biceps and forearms.
Bottom Line
If you want a pair of arms that are as strong as they look, Zottman curls deserve a place in your training arsenal. This classic movement has stood the test of time — and for good reason.
