Reverse Plate Curls
Reverse plate curls have you pinch a single weight plate between your fingers and thumbs, palms facing down, and curl it up toward your chest. The pinch grip and the pronated hand position combine two challenges most curls only give you one at a time, making this a simple but surprisingly demanding way to build forearm and grip strength alongside the brachialis. It's an accessible entry point into reverse curls since almost every gym has a spare plate lying around.
Why it works
A normal curl is graded by how much weight moves; this one is graded by whether your fingers can hold onto the plate at all. Pinching a smooth plate between your fingertips and thumb, rather than wrapping your hand fully around a bar, forces your finger flexors and thumb to work isometrically just to keep the plate from sliding out of your hand, on top of the pronated grip already shifting curl work from the biceps toward the brachialis and forearm muscles. That combination is why a plate that feels light to carry can still make your forearms burn well before your biceps ever feel challenged, which is exactly the point of the exercise. Most plates also have smoother, more slippery faces than a knurled barbell, which removes the small mechanical advantage a textured grip normally gives you and puts even more of the load directly on raw finger strength.
Set up
- Choose a single flat weight plate you can comfortably pinch between your fingers and thumb.
- Stand tall with your arm hanging at your side, palm facing your body and the plate held in a pinch grip.
- Pin your elbow to your side and brace your core before the first rep.
How to do it
- Keeping your elbow pinned to your side, curl the plate up toward your chest by bending your elbow.
- Maintain the pinch grip the entire time; don't let your palm rotate to help hold the plate.
- Raise the plate until your forearm is close to vertical, without swinging your shoulder forward.
- Pause briefly at the top, then lower the plate under control back to the starting position.
- Switch arms once you've completed all reps on one side.
Form cues
- Pinch with fingers and thumb, not a full wrap.
- Elbow stays pinned to your side.
- Lower slower than you raise.
- Stop the set the moment your grip starts to fail.
Breathing: Exhale as you curl the plate up, inhale as you lower it back down.
Common mistakes
Choosing a plate too heavy to pinch securely from the first rep.
Fix: Start with a plate light enough to hold with a confident, secure pinch for every rep of the set.
Letting the palm rotate or the wrist bend to help support the plate.
Fix: Keep the plate held purely by your fingertips and thumb, with your wrist staying flat throughout the movement.
Swinging the shoulder or leaning back to help curl the plate up.
Fix: Keep your upper arm still against your side and let your forearm do the lifting on its own.
Dropping the plate instead of setting it down once grip fails.
Fix: End the set the moment you feel your pinch slipping, and lower the plate to the floor deliberately rather than letting it fall.
How to program it
- Two or three sets of 6 to 10 reps per arm is plenty, since grip fatigue usually ends the set well before the muscle itself is exhausted.
- This pairs naturally with other grip and forearm work, so two sessions a week is a reasonable amount alongside your regular curl or pulling training.
- Save it for the end of a session, since a fatigued grip here will carry over and make heavier gripping exercises done afterward noticeably harder.
- Increase plate weight in the smallest increments your gym has available; even a couple of extra pounds changes the pinch difficulty a lot.
Safety notes
- Keep your toes clear of the plate's path in case your grip fails and it drops.
- Stop increasing the plate weight once your form starts to break down, since a plate that's too heavy to pinch safely is more likely to slip unpredictably than to build useful strength.

Frequently asked questions
What muscles do reverse plate curls work?
Mainly the brachialis and forearm flexors from the pronated curling motion, plus the finger and thumb muscles working isometrically to maintain the pinch grip on the plate.
How heavy a plate should I use for reverse plate curls?
Start with something you can pinch confidently for every rep, often a 5 to 10 pound plate to begin. The pinch grip is usually the limiting factor long before the curling motion itself feels hard.
Can I do reverse plate curls with two hands on one plate?
Yes, holding a heavier plate with both hands works too, though training one arm at a time is more common since it isolates the grip challenge on each side individually.
Why does my grip give out before my arm feels tired during reverse plate curls?
That's the exercise working as intended. The pinch grip on a smooth plate is often the weakest link, so it's common for your fingers to fatigue well before the brachialis or forearm muscles doing the actual curling.
