Reverse Curls: Flip Your Grip To Build Bigger Biceps

You can’t do much better than the tried-and-true biceps curl when it comes to pure activation in the biceps brachii, but performing them in every single arm workout really gets old fast. There’s gotta be a better way. Well, there is. Turn that frown upside-down, fit fam, and turn that grip upside-down, too!

The reverse curl is a biceps curl variation that swaps out your standard supinated grip for an overhand grip. This positioning offers the same major activation in your biceps brachii while increasing activation in surrounding muscles like the brachialis and brachioradialis. The result? Greater strength gains, improved grip strength, and, of course, bigger biceps.

Caine Wilkes, OLY, USAW-L1, and GGR senior staff writer, provides tips for doing reverse curls with proper form, variations, alternatives, benefits, and more. Check it out below!

How To Do Reverse Curls

The reverse curl features a starting position and movement pattern nearly identical to the standard barbell curl, with the distinction being the difference in the grip. You may do reverse curls using free weights, resistance bands, or even a cable machine. Additionally, you may choose to perform this biceps exercise standing or seated.

How to do it:

1. Stand holding a loaded barbell in front of your body with a pronated grip.
2. Flex your elbows to curl the bar up and toward your chest and shoulders.
3. Squeeze your biceps at the top, then slowly lower the weight back down to the starting position.
4. Repeat for reps.

Modifications

• Dial it back: Using a reverse grip makes the standard biceps curl much harder, especially on the forearm muscles, so beginners may consider working with lighter weights and a supinated grip before working up to reverse biceps curls.
• Make it harder: Going heavier is always an option, but you can up the ante in other ways. Swap out reverse curls for close-grip pull-ups or Zottman curls, or perform a 21s workout to intensify the effect on your biceps and stimulate hypertrophy.

How To Do Reverse Curls At Home

You can do reverse curls with all sorts of equipment, so you can get your reps in whether you’re working out at a super high-end commercial gym or your own barebones garage gym. Straight barbells, EZ-curl bars, dumbbells, kettlebells, resistance bands, cable machines—the list goes on.

You’re definitely not restricted to traditional workout equipment, either. Lifting a heavy jug of laundry detergent, a gallon jug of water, or a loaded laundry basket will work just as well. As long as you’re using an overhand grip, you’ll hit the target muscles all the same.

Reverse Curl Variations

Dumbbell Reverse Curl

Using a pair of dumbbells instead of a barbell makes sure each arm bears the full brunt of the exercise so you can help correct muscular imbalances and strength deficits. Dumbbell reverse curls also enable a fuller range of motion.

Kettlebell Reverse Curl

Using kettlebells instead of dumbbells offers the same benefits; however, the weight distribution makes the movement even more challenging by recruiting more stabilizer muscles for more work per rep.

Reverse Cable Curl

A study performed by the American Council on Exercise¹ found that the cable curl was one of the best biceps exercises of all time. So, doing the reverse curl with a cable machine provides that same high level of activation for massive gains.

Reverse Curl Alternatives

The standard biceps curl and reverse curl exercises are great, but you’ll need more if you want to program a comprehensive arm workout. So, here are a few more upper body and arm exercises to help you build muscle and get a good pump on! 

Hammer Curl 

Why do it: “Hammer curls involve the same movement pattern as a standard biceps curl or reverse curl, but with a neutral grip,” says Caine Wilkes, OLY, USAW-L1. “This positioning offers more stability to your wrist and elbow joints and often allows the lifter to work with heavier weights.”

How to do it:

1. Stand with your feet shoulder-width apart and two dumbbells held with a neutral grip.
2. Flex your elbows to curl the dumbbells toward your shoulders.
3. Squeeze your biceps at the top, then slowly return to the starting position.
4. Repeat for reps.

Wide-Grip Bent-Over Barbell Row

Why do it: The wide-grip bent-over barbell row as a reverse curl alternative is a double-edged sword. On one hand, using a wider grip during rowing exercises decreases activation in the biceps brachii, according to the Journal of Strength and Conditioning Research²; on the other hand, you get significantly more activation in your forearm muscles, contributing to some huge increases in grip strength.

How to do it: 

1. Stand over a loaded barbell with your feet shoulder-width apart.
2. Hinge forward, grip the bar with a wide overhand grip, and deadlift it off the floor.
3. Tilt your torso forward, keeping your back straight and your arms fully extended.
4. Row the barbell toward your stomach, pinching your shoulder blades at the top.
5. Squeeze the contraction, then slowly lower the weight back down.
6. Repeat for reps.

Pull-Up

Why do it: Pull-ups and chin-ups are among the best bodyweight biceps exercises you can do, targeting muscles like your back, chest, triceps, and (of course) biceps in one succinct movement. They can also help improve your lifting strength, grip strength, and muscle size.

How to do it: 

1. Grab onto a pull-up bar using an overhand grip and enter a dead hang.
2. Engage your lats and bend your elbows to pull your body toward the bar.
3. Continue until your chin passes over the bar.
4. Squeeze the contraction, then lower yourself back down with control.
5. Repeat for reps.

Zottman Curl

Why do it: Why do standard and reverse curls when you can do one curl variation that offers the best of both worlds? The Zottman curl involves twisting from a reverse grip to a supinated grip as you move, hitting your biceps, forearm flexors, and forearm extensors.

How to do it: 

1. Stand holding a pair of the best dumbbells with your palms facing forward.
2. Engage your biceps and flex your elbows to curl the dumbbells toward your shoulders.
3. Squeeze your biceps at the top, then rotate your forearms so your palms now face away from you.
4. Lower your dumbbells back down to the starting position with control.
5. Rotate your forearms so your palms face forward again.
6. Repeat for reps.

Preacher Curl

Why do it: “Biceps curls require keeping your elbow stationary, which gets tough once you’re working with heavy weights,” says Caine. “The preacher curl solves the problem by providing a place for your upper arm and elbow to rest, so you rely solely on elbow flexion and the strength of your biceps to do the movement.”

How to do it: 

1. Adjust a preacher pad so that your upper arms and chest can rest against it.
2. Load a barbell or EZ-curl bar to your desired weight.
3. Grip the bar using an underhand grip, keeping your elbows fully extended, then sit down and lay your arms flat on the preacher pad.
4. Flex your elbows to curl the bar toward your shoulders, keeping your upper arms and elbows in place.
5. Continue until your elbows are fully flexed, squeezing your biceps at the top.
6. Slowly return the bar to the starting position.
7. Repeat for reps.

Benefits of Reverse Curls

The standard biceps curl, reverse curl, and other curl variations generally target the same muscle groups, so what makes the reverse curl so beneficial?

May Increase Your Grip Strength and Shoulder Stability

The primary muscle used during the standard biceps curl exercise is the biceps brachii, but the exercise also hits the brachialis and brachioradialis muscles to some degree. These forearm muscles are largely responsible for your grip strength.

According to Sports (Basel)³, the reverse curl—due to its pronated grip—works these vital muscle groups to build greater grip strength. The reverse grip also increases activation in your anterior deltoid, helping stabilize your shoulder joint.

Provides Training Diversity

The standard biceps curl is one of the few isolation exercises that target the biceps brachii, so we highly recommend that your arm workouts include some form of biceps curls if you want to build bigger biceps. That said, you may find yourself getting mind-numbingly bored doing the same old biceps curl exercise for every workout.

The reverse curl offers some variety to help you stave off training boredom, but that’s not all. According to PLoS One⁴, “varying exercise selection [has] a positive effect on enhancing motivation to train” but also “[elicits] similar improvements in muscular adaptations,” which may equal greater gains.

Another study in the Journal of Strength and Conditioning Research⁵ confirmed these findings, indicating that systematically switching things up with new exercise variations “seems to enhance regional hypertrophic adaptations and maximize dynamic strength.”

So, working curl variations like the reverse curl into your programming may improve motivation and increase strength and hypertrophy gains, too. Win-win!

May Strengthen Your Wrist Joint

Proper reverse curl form involves maintaining a strong, stable, neutral wrist positioning, meaning you must activate your wrist extensors from start to finish. So, similar to how wrist curls work the smaller muscles that support your wrist, the reverse biceps curl does the same and, over time, may contribute to stronger, more stable wrists.

More wrist mobility and stability is great for navigating your everyday life with minimal risk of injury, but it also translates to better weightlifting performance in the gym, which, in turn, fuels sizable gains all around.

Common Reverse Curl Mistakes

It doesn’t matter if you’re blasting out barbell reverse curls, doing them with dumbbells, or cranking out reps with kettlebells; your results will leave something to be desired if you don’t do the exercise with proper form. Here are a few common mistakes to avoid.

Using Too Much Momentum

The tricky thing about using momentum for reverse curls (and most curl variations, for that matter) is that you may not realize you’re doing it, especially when you’re standing.

“The reverse curl is all about flexing your elbows to curl the weight toward your shoulders,” says Caine Wilkes, OLY, USAW-L1, “but, as fatigue sets in, you tend to get a little extra help from your hips or upper-body muscles. This takes the emphasis off the target muscle groups and hurts your results.”

To prevent body English from diminishing your gains, keep your elbows stationary throughout the entire movement. You want to use elbow flexion to move the weight, and that’s it!

Improper Wrist Positioning

Using a reverse grip places more strain on the wrist, which ultimately may contribute to greater wrist strength and stability. Improper wrist positioning, however, may hamper these gains and, instead, increase your risk of injury.

“Holding the weights with an overhand grip will pull your wrists forward into a flexed position, which results in stress on the joint and may cause or contribute to an injury,” says Caine. “You have to fight against this pull and maintain strong, rigid, neutral wrists.”

Start with lighter weights and progress gradually to give yourself your best chance at maintaining the proper neutral wrist positioning.

Lifting With Poor Posture

It doesn’t matter if you’re doing bar reverse curls, upright rows, deadlifts, or some other standing exercise; you must lift with good posture to maximize movement efficiency, generate power, and keep your risk of injury low.

“Holding a heavy barbell in front of your body may pull you forward and cause you to round your back or shoulders forward unintentionally,” says Caine, “this is inefficient and may be the reason why you get hurt in the gym.”

Before you do a single rep, check in with your form. Here’s a quick rundown of what you want:

• Neutral neck
• Eyes tracking forward
• Tall chest
• Straight back
• Shoulders down and back
• Core braced
• Elbows tucked into your torso
• Wrists neutral and strong
• Knees slightly bent
• Feet shoulder-width apart

Working out in front of a mirror may help you spot problems with your form, but you can’t beat the convenience of having a certified personal trainer supervising. Consider working with one if you’re having trouble with your form.

Muscles Worked by Reverse Curls

The reverse curl is a single-joint movement categorized as an isolation exercise, but that doesn’t mean that only one muscle or muscle group gets activated. The primary muscles involved in the reverse curl include:

• Biceps brachii: The main objective of biceps curls and curl variations is to hit this major muscle of the upper arm, which assists with elbow flexion and shoulder stabilization. While the biceps are functional, most lifters like working them for aesthetics.
• Brachialis: The brachialis sits beneath the biceps brachii and is the actual primary mover involved in elbow flexion, making it arguably more integral to the movement.
• Brachioradialis: The brachioradialis muscle, a forearm muscle that greatly assists with your grip, receives a ton of activation during the reverse curl due to the wrist positioning. 
• Core: If you’re performing your reverse curls standing, you’ll need to brace your core to maintain a rigid, upright posture.

Reverse Curls: Final Thoughts

The reverse-grip biceps curl is a highly-effective biceps curl variation that may:

• Help build bigger biceps
• Improve your grip strength
• Enhance your shoulder, elbow, and wrist stability
• Keep your arm workouts fresh and varied

So, don’t stick to the same standard curl every week; switch things up and work the reverse curl into your next training session!
