Every time you pick something up or hang onto something heavy, your forearms are doing work. They get plenty of indirect volume from daily life and heavy pulling. If you want them bigger and stronger, though, they need progressive overload like any other muscle.
Direct forearm training isn’t a popular topic, but a handful of simple cable exercises can add real size and strength to your lower arms. This article covers the best ones.
Cables keep constant tension on the working muscle through the entire range of motion, which is exactly what you want for hypertrophy work. With a few attachments, you can train every action of the forearm: flexion, extension, deviation, and rotation. Most people just do wrist curls, and they’re leaving a lot on the table.

Cable Wrist Curls
Benefits of cable wrist curls
The cable wrist curl is the staple of direct forearm training. If you only add one exercise from this list, make it this one.
The cable wrist curl directly targets the wrist flexors, which make up a large portion of the forearm. Think of your wrist flexors as the bicep of the lower arm, whereas the extensors are the triceps of the lower arm.
Beyond size, wrist curls build grip strength that carries over to the deadlift, farmer’s carries, and the Olympic lifts.
How to perform cable wrist curls
You can do these standing or seated with your forearms supported on your thighs. The instructions below cover the standing version. In the video, Jim Stoppani demonstrates the seated version. Try both and see which feels better.
- Adjust the cable pulley to the lowest position, attach a straight bar to the cable, and select an appropriate amount of weight.
- Stand facing the cable with a shoulder-width stance. Lean over and grab the cable with a supinated grip (palms facing up) that’s just inside shoulder width.
- Stand up straight with your arms extended in front of you and your wrists straight. There should be some tension on the cable. This is the starting position.
- Begin the movement by taking a deep breath, bracing your core, and curling your wrist towards your forearm. Keep your upper arm stable and elbow straight throughout the entire movement. The only thing that should be moving is your wrist.
- Once you reach peak contraction, pause for 1-2 seconds before exhaling and lowering the bar back to the starting position by extending your wrist back to neutral.
- Repeat for the desired number of repetitions.

Cable Reverse Wrist Curls
Benefits of cable reverse forearm curls
If you’re doing cable wrist curls regularly, pair them with cable reverse wrist curls. You can even superset them (one movement right after the other, no rest) to save time.
The cable reverse wrist curl targets the wrist extensors, the opposite side of the forearm from the flexors. If you want complete forearm development, run wrist curls and reverse wrist curls in the same program. Doing only one is like training your biceps and skipping your triceps.
Like cable wrist curls, these strengthen your grip. They’re also easy to learn and cheap on recovery, so there’s little downside to adding them.
How to perform cable reverse forearm curls
Same deal as the cable wrist curl: standing, or seated with your forearms supported. The instructions below cover the standing version.
- Set the cable pulley to the lowest position, attach a straight bar or cambered bar to the cable, and select an appropriate amount of weight.
- Stand facing the cable with a shoulder-width stance. Lean over and grab the cable with a pronated grip (palms facing down) that’s slightly inside shoulder width.
- Stand up straight, then bend your elbows until your arms form a 90-degree angle. Your wrist should be in a neutral position. This is the starting position. Make sure to keep your upper arms stable and elbow bent to 90-degrees throughout the entire movement. The only thing that should be moving is your wrists.
- Begin the movement by inhaling, bracing your core, and extending your wrist back towards your forearm.
- At the top of the rep, hold the contraction for 1-2 seconds before slowly moving your wrist back to neutral.
- Repeat for the desired number of repetitions.

Cable Radial Deviation
Benefits of cable radial deviation
Cable wrist curls and reverse cable wrist curls are the most popular exercises for building the forearms, but the wrist does a lot more than just flex and extend. Two other motions that the wrist can perform are radial deviation and ulnar deviation, also known as abduction and adduction.
These look minor, but they hit forearm muscles that flexion and extension miss. They also build wrist mobility and stability, which pays off if your wrists take a beating from pressing.
During radial deviation you’re working the flexor carpi radialis and extensor carpi radialis. The radius is the forearm bone on your thumb side (more on anatomy below). You do this one arm at a time, so it also helps even out side-to-side imbalances.
How to perform cable radial deviation
- Adjust the cable pulley to the lowest setting, attach a D-handle to the cable, and select an appropriate amount of weight.
- Stand facing away from the cable pulley with a shoulder-width stance. Bend down and grab the handle with your weaker side (left or right) using a neutral grip (palms facing torso with thumb forward).
- Stand up straight with your arm extended and hold the handle at your side. The only thing that should be moving is your hand and wrist.
- Begin the movement by inhaling, bracing your core, and moving your thumb up towards your wrist via radial deviation.
- Once you can’t go any farther up, hold for 1-2 seconds before exhaling and returning your hand back to neutral.
- Repeat for the desired number of repetitions and do the same thing on the other side.

Cable Ulnar Deviation
Benefits of cable ulnar deviation
If you are performing radial deviation exercises, performing ulnar deviation is important because it’s the opposite movement pattern. The cable ulnar deviation exercise targets the flexor carpi ulnaris and extensor carpi ulnaris. The ulna is the other bone that makes up the forearm and it’s located on your pinky side.
This one builds wrist strength and stability through a range most lifters never train. If you have cranky wrists, cable ulnar deviation and cable radial deviation are worth adding to your program.
Since this exercise is performed unilaterally, start with your weaker side and match the number of reps you get with the other arm. This will help correct any strength imbalances.
How to perform cable ulnar deviation
- Adjust the cable pulley to the lowest position, attach a D-handle to it, and select an appropriate amount of weight.
- Stand facing away from the cable pulley with a shoulder-width stance.
- Grab the cable with your weaker side using a neutral grip (palms facing your torso with your thumb facing up). With your arm extended, position it at the side of your body and keep it there throughout the entire movement. The only thing that should be moving is your hand and wrist.
- Begin the movement by inhaling, brace your core, and bring your pinky towards your forearm via ulnar deviation.
- Once you can’t go any farther, hold the contraction for 1-2 seconds.
- Slowly lower your wrist back to neutral.
- Repeat for the desired number of repetitions and do the same thing on the opposite side.

Reverse Cable Curls
Benefits of reverse cable curls
Reverse cable curls are known as a bicep exercise, but they’re also one of the best forearm builders you can do.
Besides the biceps brachii and brachialis, reverse cable curls work the brachioradialis, which is the most superficial muscle on the radial (thumb) side of the forearm. It’s one of the largest muscles in the forearm, so building it up with reverse cable curls is a quick way to make your forearms look bigger.
Reverse cable curls also strengthen the forearm extensors, so you get biceps and forearm work in one exercise. You can load them heavier than anything else on this list, which makes progressive overload easy.
You can use a straight bar or an EZ bar. The EZ bar is usually friendlier on the wrists; here’s our full breakdown of EZ curl bar vs straight bar curls if you’re not sure which to grab. For more curl variations that hit the forearms, see our list of cable curl alternatives.
How to perform reverse cable curls
- Adjust the cable to the lowest setting, attach a straight bar or EZ bar to the cable, and select an appropriate amount of weight.
- Stand facing the cable with a shoulder-width stance. Bend over and grab the bar with a double overhand (pronated) grip that’s about shoulder-width apart.
- Stand up straight with your arms extended in front of you and take 1-2 steps away from the tower.
- Assume a shoulder-width stance, lock your elbows at the sides of your body, and keep your upper arm stable throughout the entire movement. This is the starting position.
- Inhale, brace your core, and begin the movement by bending your arms at the elbows.
- Once you’ve reached full flexion, pause for 1-2 seconds.
- Exhale as you slowly lower the bar back to the starting position.
- Repeat for the desired number of repetitions.
Watch the video below for a video demonstration of the reverse cable curl.
Cable Zottman Curl (Pronation & Supination)
Benefits of cable Zottman curls
The Zottman curl is an old-school bicep curl variation with a twist (literally). The Zottman curls consist of a traditional supinating bicep curl, but on the way down, you twist into a reverse curl. Although it’s an effective bicep exercise, the primary reason that it made this list is because you perform supination and pronation in the same movement.
Similar to ulnar and radial deviation, pronation and supination are two minor, yet important actions that the forearms perform. The forearm muscles responsible for pronation are the pronator teres, pronator quadratus, and brachioradialis. On the other hand, the forearm muscles responsible for supination are primarily the supinator, along with the biceps brachii.
The Zottman curl trains all of these muscles in one exercise. It’s usually done with dumbbells, but a D-handle works fine for the cable version: one arm at a time, or both at once if your gym’s cable stacks are close together.
How to perform cable Zottman curls
- Adjust a cable pulley to the lowest position, attach a D-handle to the cable, and select an appropriate amount of weight.
- Stand facing away from the cable, bend down and grab the cable with your right or left arm (whichever is weaker) with a supinated grip (palms facing up).
- Stand up straight and take 1-2 steps away from the cable pulley until there’s tension on the cable. Assume a shoulder-width stance and hold the handle at your side with your arm extended. Keep your elbow locked at your side and upper arm stable throughout the movement.
- Inhale, brace your core, and begin the movement by flexing your arm at your elbow. Focus on bringing your pinky higher than your thumb to achieve greater supination at the top of the rep.
- Once you’ve reached full flexion, hold for 1-2 seconds.
- On the eccentric (lowering) portion, pronate your forearms (palms facing down) and slowly extend your arms back to the starting position.
- Before doing the next rep, move your forearms/wrists back into supination and repeat for the desired number of repetitions.
- Match the number of reps with the other arm.

Cable Static Hold
Benefits of the cable static hold
The last exercise on our list is a cable static hold. One of the most popular ways to increase your grip strength is simply by holding something heavy for a given period. Static holds are typically performed with dumbbells while walking for a certain distance, also known as farmer’s carries.
Static holds hammer your traps and upper back along with your grip, and they make a great finisher when your forearms are already cooked. A rope attachment makes it harder. If you’re building out a full cable day, our cable low back exercises pair well at the end of the same session.
No video needed for this one: grab the attachment, stand up, and don’t let go.
How to perform the cable static hold
- Adjust the cable pulley to the lowest position, attach a rope attachment to the cable, and select an appropriate amount of weight.
- Stand facing the cable, lean forward, and grab the rope with a neutral or pronated grip.
- Take 1-2 steps away from the cable and assume a shoulder-width stance.
- Keep your arms fully extended in front of your body.
- Hold the cable for as long as you can. Time yourself and aim to beat your time or use a heavier weight for the same amount of time.

Forearm Anatomy
Roughly 20 muscles make up the forearm, and they can be categorized by their location. The anterior compartment of the forearm is where you will find all of the muscles that flex the wrist and fingers. It’s divided into three layers – superficial, intermediate, and deep.
The superficial layer contains the flexor carpi ulnaris, palmaris longus, flexor carpi radialis, and prontator teres. The intermediate layer only contains the flexor digitorum superficialis. The deep layer contains the pronator quadratus, flexor digitorum profundus, and flexor pollicis longus.
The posterior compartment of the forearm is where you’ll find all of the wrist and finger extensors. It’s divided into just two layers – superficial and deep. The superficial layer contains seven muscles including:
- Brachioradialis
- Extensor carpi radialis longus and brevis
- Extensor digitorum
- Extensor digiti minimi
- Extensor carpi ulnaris
- Anconeus
The deep layer of the posterior compartment contains the following muscles:
- Supinator
- Abductor pollicus longus
- Extensor pollicus longus and brevis
- Extensor indicis

Frequently Asked Questions
The number of times per week you train forearms depends on your ability to recover, how much week volume you’re performing, and availability to train based on your schedule. According to Renaissance Periodization, the optimal training frequency for forearm hypertrophy is somewhere between 3-6 sessions per week.
If you can only make it to the gym 3 times per week, then training your forearms for 5 days isn’t going to work. It is critical to set realistic expectations. Even if you can train 6 days per week, if your forearms are still very sore after the second time of training them, allow them to rest and recover before hitting them again.
Although 3-6 times is the recommendation, you’re going to have to find out what training frequency works best for you.
The forearms are involved in several different exercises, so they don’t necessarily need direct work to maintain. However, if you notice that your grip is weak or you would simply like to increase the size of your forearms, adding in some isolation exercises is a good idea.
If you’re rehabbing from a wrist injury, then performing direct forearm training will likely help decrease the recovery time and hopefully prevent future injuries. Forearm and wrist issues are quite common in the lifting community, so consider doing forearm training to stay in the game a little longer!
The forearms can benefit from training intensities between 30%-85% of your 1-rep max. For optimal results, perform at least half of your direct forearm training between 60-70%. The other half can be performed above 70% and/or below 60%.
Some exercises lend themselves better to a higher training intensity (heavier weight) such as reverse curls and static holds. On the other hand, corrective exercises such as radial and ulnar deviation should be performed with a lighter intensity (lower weight).
For forearm hypertrophy, it’s recommended to do at least 50% of your forearm training in the 10-20 rep range. The other 50% should be evenly divided between the 5-10 rep range and the 20-30 rep range.
As long as you are training close to failure (within 1-4 reps), any of the rep ranges listed above will result in muscle growth and strength gains. Using a variety of rep ranges keeps training fun and stimulates different muscle fiber types, which is ideal for overall hypertrophy.
