Zottman curls combine supinated curls on the way up with pronated lowering on the way down. You curl with palms up (working biceps), rotate at the top, then lower with palms down (working forearms and brachioradialis). This dual-action trains both muscle groups in a single exercise.
When to use it
Use when you want to train biceps and forearms together efficiently.
Who it's for
Intermediate lifters wanting complete arm development.
Curl up with palms facing the ceiling as normal. At the top, rotate your wrists 180 degrees so palms face down. Lower the weight slowly with the overhand grip, controlling the eccentric. At the bottom, rotate back to palms up for the next rep.

We slot it into the right day with sets, reps, and progression you can follow.
Stand holding dumbbells with palms facing forward.
Curl weights up with supinated (underhand) grip.
At the top, rotate wrists to pronated (overhand) grip.
Lower the weights with overhand grip.
At the bottom, rotate back to underhand grip.
Repeat for desired reps.
The rotation targets both biceps and forearms.
Control the negative with the overhand grip.
Use moderate weight to maintain proper form.
Use Zottman curls when you want to train biceps and forearms efficiently in the same movement. They work well as a secondary movement or finisher in arm workouts. The forearm-heavy eccentric makes them excellent for grip development.
Rotating too early - reduces bicep engagement on curl.
On pulling movements like the Zottman Curl, this mistake typically means your arms are doing work that should come from your Biceps brachii. Initiate every rep by engaging your Biceps brachii first, then let your arms follow.
Dropping weight too fast on negative - misses forearm work.
Rushing through the Zottman Curl reduces the time your Biceps brachii spends under tension — which is one of the main drivers of growth. Aim for a controlled 2-second lowering phase on every rep.
Using too heavy weight - compromises rotation.
Loading more weight than you can control on the Zottman Curl forces compensatory movement patterns that bypass your Biceps brachii. Drop the weight until you can perform every rep with clean form — your results will actually improve.
Intermediate lifters wanting complete arm development.
Lower reps with heavier weight builds raw strength. Your muscles and nervous system adapt to handle more load over time. This range is best for strength-focused goals.
This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.
Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.
General guideline: 3 sets of 10-12 reps. Rest 60 seconds.
