11 Best Cable Arm Exercises for Size & Strength

January 24, 2022

There's a reason why you walk into a gym and the cable machines are all taken like the benches on a Monday. Because the cable machine gives you great options to train your whole body. Plus, the variety of attachments from ropes, d-handles, and straight bars allows you to change grips and angles for better muscle development.

When it comes to training biceps and triceps, the cable machine has a prominent place right along side dumbbells and barbells. What makes the cable machine really special compared to free weights is the flat resistance. There is no strength curve, the resistance never changes throughout the range of motion. This means more hypertrophy for you.

In this post, our focus is using the cable machine to hit the arms. We put together the 11 best cable exercises for the biceps and triceps that you should add to your arm workout. We also go over things like the anatomy and function of the bi's and tri's, as well as the benefits of using the cable machine. Not only will this give you a deeper understanding of the implement and your muscles, but it will also become clear why we chose these particular arm exercises.

BICEPS AND TRICEPS ANATOMY AND FUNCTION

BICEPS ANATOMY

The biceps brachii (biceps for short) is made up of two muscle heads, the short head and long head, located on the front side of the upper arm. The long head of the biceps originates on the supraglenoid tubercle of the scapula and inserts on the radius bone near the elbow. The short head also originates on the scapula, near the A/C joint, and inserts radius bone (which is one of your forearm bones). Put simply, both heads have different origin points but they converge to form the same muscle belly (that bicep ball when you flex) and insert into the same place.

BICEPS FUNCTIONS

The biceps muscles cross the elbow and shoulder joint, so it acts on both joints. When both biceps heads shorten it leads to elbow flexion, which is the main movement of the biceps (i.e. a curl). The other main elbow movement is rotating the forearm outwards known as supination. This movement is more effective when the elbow is flexed. As the biceps cross the shoulder joint, they also assist in shoulder abduction, which is when the arm pulls away from the torso. Plus, it assists in shoulder adduction (coming back to the torso) and inward rotation of the arm.

Moreover, the biceps and triceps muscles work together to support the humeral head in the shoulder joint otherwise known as shoulder stability.

TRICEPS ANATOMY

The triceps is Latin for three and the triceps is a three-headed muscle that sits on the edge of the arm. This muscle makes up 60% of the upper arm. The medial head, lateral head, and long head come together at the same insertion point across the elbow at the humerus, but each has different origin points.

While the three heads have some individual functions, together the triceps primary movement is that of an elbow extensor (extending the arm at the elbow) because it crosses the elbow joint.

Now, to get specific, the medial head originates from the inferior two-thirds of the humerus (middle of the arm) and is between and underneath the other two heads. It is used for low force extension (which means it is activated any time your extend your elbow).

The long head originates from infraglenoid tubercle of the scapula (shoulder joint), which is near the glenoid fossa. Because it crosses the shoulder and elbows joint it functions as elbow and shoulder extension.

The lateral head originates from a narrow, linear ridge on the back of the humerus, above the radial groove. Its function is opposite of the medial head because it’s responsible for high force power production (really only activated when acting against resistance). It’s located on the outside of the arm hence the word lateral and it is the largest of the three heads.

TRICEPS FUNCTION

If you haven’t guessed by now the number one job of the triceps is to extend the elbow. Having strong triceps is important for a strong lockout for pressing exercises such as the bench, overhead presses, and push-ups. And because the long head crosses the shoulder joint its secondary job is to assist with shoulder extension and shoulder stability.

FOREARMS: Your arms also include your forearms, which consists of several major muscles that we will group together for the sake of simplicity and call them your forearm extensors and flexors. The forearms play an important role in the movement of your elbow, wrists and fingers. Weak forearms, mean weak grip strength, which can cause a kinetic chain effect up your elbow to your shoulder. In other words, you can NOT forget about the forearms. The cable exercises in the guide will also work your forearms.

Biceps’ Head Activation Tips:

Long Head Biceps Activation (Biceps Peak):

Bring your hands closer together (close grip).
Use a neutral grip, aka hammer grip.
Curling with your elbows at your side.
Curling with your elbows back behind you.

Short Head Biceps Activation (Biceps Width):

Curl with your elbows in front of your body (upper arm held up parallel with the floor).
Curl with a wide grip.
Curl with a supinated grip (palm held upward and outward.
Curl with your arms held laterally toward your body.

Triceps’ Head Activation Tips:

Medial Head Triceps Activation:

Use a reverse grip (underhand grip).
Keep your elbows at your sides.
Responds better to higher reps.

Lateral Head Triceps Activation:

Keep elbows at your side.
Use an overhand grip.
Responds better to heavier loads.

Long Head Triceps Activation:

Elbows overhead.
Elbows out in front of you (both overhead and elbow up work your long head from a stretched position).

BENEFITS OF TRAINING THE BICEPS AND TRICEPS

Besides the perfectly acceptable vanity reason of having some impressive guns, there are important reasons why you should include biceps and triceps exercises in your accessory routine:

Better Shoulder Stability: All the muscles which attach to the shoulder joint and scapula assist in shoulder stability. The biceps helps the rotator cuff to secure the humerus to the shoulder joint from both sides and this compression benefits your shoulder stability. Plus, the long head attaches to the shoulder to assist with most movements of the shoulder and to provide stability for the scapula.
Elbow Health: The triceps and biceps tendons attach in and around the elbow. Strengthening the triceps and biceps muscles also strengthen the tendons and bones surrounding the elbow joint too, to help keep your elbows healthy and strong.
Lift More Weight: You’re only as strong as your weakest link. Because the biceps and triceps assist in compound moves such as chin-ups, rows, bench, and overhead pressing, having strong bi’s and tri’s will help you lift more weight. Wouldn’t it be a shame for your triceps to give out and the barbell come crushing towards your chest? Or, in a more common scenario, your arms tiring out before the more major muscle group you are targeting had enough time under tension.
Better Sports Performance: Any sport where you hit a ball, fend off an opponent, or throw a ball hard and fast needs triceps and biceps strength and endurance. Why? Because a lot of sporting actions use elbow flexion and extension.

ADVANTAGES OF TRAINING ARMS ON THE CABLE MACHINE

More Core Work: Because most cable machine exercises are performed standing, training on the cable machine engages the muscles of the lower back, hips, obliques, and abs. Otherwise, known as the ‘core” Plus when you train unilaterally, this takes it all up a notch.
Constant Tension Throughout The Range Of Motion: Each free weight strength exercise has a strength curve. The strength curve is the force generated at each point throughout an exercise's ROM. Because of your joint angles, the resistance is not constant. But not so with the cable machine which provides constant tension throughout the ROM which can result in more muscle and strength.
Variety: There is a multitude of exercises that can be done on the cable machine with a choice of handles that allow you to vary your grip also. Plus, you can switch between exercises with minimum fuss which allows you to do more work in less time.
Muscle Development: With the cable machine's freedom of movement, combined with the ability to go high and low and to change handles, you’ll be able to train the muscles from a variety of angles for total muscle development.

11 BEST CABLE MACHINE ARM EXERCISES

Here are 11 cable triceps and biceps exercises that will train the gun show to maximum capacity. Are you ready to flex? Then let’s go.

1. Reverse Cable Biceps Curl

Using a straight bar attachment with an overhand grip the reverse biceps curl trains the smaller forearm extensor muscles that can get overpowered by the larger forearm flexor muscles. Although the extensor muscles are small, training them will go a long way to keeping your elbows healthy. This exercise will of course also work your biceps. The reverse grip curl best activates the long head of the biceps due to the pronated grip.

How to do the Reverse Cable Biceps Curl:

With the cable machine on its lowest setting hold a straight bar with an overhand grip, your knuckles facing away from you.
Keep your wrists in neutral while you curl the straight bar to the front of your shoulders.
Pause for a second and slowly return to the starting position.
Resets and repeat for reps.

Form tips: The reverse overhand grip is your weakest grip for curls and for this reason, you will use less weight than other variations. It is imperative to keep the wrists in neutral through this exercise.

Best rep range: 8-15

2. Underhand Cable Biceps Curl

The underhanded grip biceps curl trains both heads of the biceps and the biggest forearm muscles and is by far your strongest grip. This allows you to load up more than any other variation. When using the straight bar, you can vary your grip in and out to train the short and long head of the biceps (more wide = more short head).

How to do the Underhand Cable Biceps Curl:

With the pulley on the lowest setting, hold a straight bar with an underhand grip with the grip width of your choice.
Walk back until the weight stack is separated and your feel tension.
Curl the straight bar to the front of your shoulders and squeeze the biceps at the top of the contraction.
Slowly lower until elbows are straight.
Reset and repeat for reps.

Form tips: Keep your upper back tight to prevent leaning too far forward. Vary the width of your grip from set to set to train both the short and long heads of the biceps.

Best rep range: 8-20

3. Unilateral Cable Preacher Biceps Curl

For this you can pull the preacher bench to the cable machine or simply set up an incline bench some distance away from the cable machine which simulates an effective bicep curl variation of the preacher's biceps curl. The preacher curl is a great exercise for the short head as it involves elbow flexion with your elbows out in front of you. If done unilaterally with a stirrup handle, you can strengthen imbalances between biceps while taking the biceps through a large range of motion.

How to do the Unilateral Cable Preacher Biceps Curl:

Set up the pulley a few rungs above the bottom and attach the handle to the cable.
Walk back and place your upper arm on the incline bench with an underhand grip with your elbow straight.
Curl the handle to the top of your shoulder and pause for a second.
Slowly lower until your elbow is straight.
Reset and repeat.

Best rep range: 8-12

Form tips: Keep your posterior upper arm glued to the bench at all times. This will put the focus entirely on the biceps.

4. Cable Rope Curl

The cable rope curl needs to be a staple in your cable arm routine because it’s similar to dumbbell hammer curls. The neutral grip is easier on your elbows and shoulders because your shoulder is neither externally nor internally rotated. Hammer curls train the long head of the bicep and the brachioradialis which is an important and neglected forearm muscle.

How to do the Cable Rope Curl:

Start by clipping a rope attachment to the cable machine, set at the lowest setting on the pulley.
Grip the rope on both ends in a neutral grip and walk back until you feel the tension.
Keeping your wrists in neutral, curl until the rope is near your shoulders.
Pause for a second and then slowly lower down until your arms a straight.
Slowly lower down to the starting position and repeat for reps.

Best rep range: 12-20

Form tips: Spreading the rope apart at the end of the movement will give your biceps an extra contraction. If the end of the ropes handles bother you, hold it lower down.

5. Overhead Cable Biceps Curl

The overhand cable biceps curl trains the biceps laterally instead of anteriorly. And this exercise great option to target the biceps (both heads, with emphasis on the short head) and grow your arms from a different angle. Depending on the cable machine you need to be able to fully flex and extend your elbow. If the cable machine is too small, do one arm at a time.

How to do the Overhead Cable Biceps Curl:

Set the pulley on each side at shoulder height with a stirrup handle.
Stand in the middle of the cable machine with a handle in each hand.
With both arms straight pull the handles towards your shoulders
Keep your wrists in neutral and squeeze the biceps at the end of the curl.
Slowly straighten your arms to return to the starting position.
Reset and repeat.

Best rep range: 12-15

Form tips: Fully flex and extend your elbows and perform the exercise with tempo to really feel the biceps muscles working.

6. Supine Cable Biceps Curl

When you’re looking to spice up your cable curl game, try supine cable curls. This variation gives you more stability which drives more action to your biceps. Plus, because you’re lying down, you cheat less, again putting more focus on the biceps. And you’re training them from a different angle for better muscle development. A standard grip with a straight bar attachment is great for both heads of the biceps, but you can play around with grip width and attachments if you want to emphasize the activation of a specific biceps head.

How to do the Supine Cable Biceps Curl:

Set up the pulley with a straight bar attachment at hip height and place a weight bench at leg length away from the cable machine.
Hold the straight bar with both hands and lie back on the bench and place your feet on the cable machine or on the floor.
Hold the straight bar with your elbows straight and core engaged to keep your back neutral.
Then curl the attachment until your biceps are fully flexed with the wrists in neutral.
Slowly return to the starting position and reset and repeat.

Best rep range: 8-20

Form tips: Make sure you keep your back flat on the bench and only use your biceps to curl the weight. Start on the lighter side until you get the hang of it.

7. Supine Cable Triceps Extension (Skull Crusher)

Similar setup to the supine cable bicep curl except the weight is behind you. Think of a triceps skull crusher but with a cable machine. Because you’re lying down it drives more engagement to the triceps, and you cannot use other parts of the body. The large range of motion and the pre-stretch before the contraction make this a solid option for building muscular triceps. As for triceps muscle head activation, since your arms will be out in front of you, it emphasizes the long head, but it is also great for the lateral head and medial head.

How to do The Supine Cable Triceps Extension:

Set up the pulley above weight bench height with a rope attachment
With the weight stack behind you, grab the rope with both hands and lie down on the bench with your feet on the ground.
Bend the elbows to lower back behind your head.
Straighten the elbows, keeping the wrists in neutral, and squeeze the triceps when fully extended.
Bend the elbows as you’re returning to the starting position.
Reset and repeat.

Best rep range: 12-20

Form tips: Keep your body glued to the bench to only use your triceps.

8. Unilateral Cable Triceps Pushdown

Like with all unilateral exercises the unilateral triceps extension will strengthen muscle imbalances between sides if any exist. Using a d-handle attachment, you can perform triceps pushdown with an overhand or underhand grip. Changing your grip and position with the exercise will allow you to effectively train all 3 heads of the triceps.

A v-handle is also good if going overhand as it pronates your hands almost halfway between neutral and overhand, which is easy on the wrists and allows for greater loads.

How to do The Unilateral Cable Triceps Pushdowns.

Set the pulley to its highest point with a d-handle or v-handle.
Take an under/overhand grip and bring your arm to your side and have a slight forward lean of your torso.
Your arm should be flexed.
Pushdown until your elbow is fully extended and pause.
Slowly return to the starting position and reset and repeat.

Note: You can also use a straight bar attachment to do underhand (reverse grip) triceps pushdowns, which will better emphasize your medial triceps head.

Best rep range: 8-15

Form tips: Slight forward lean of the torso hits the triceps more effectively.

Try to hit it from a different angle too!

9. Overhead Triceps Extension

Overhead triceps extension hits all three triceps heads but with a focus on the long head. This is not the strongest triceps muscle (that’s the lateral head) but it is the biggest and adding muscle to this will make your arms look bigger for more flex appeal. This variation will improve your lockout strength, particularly with any overhead press variation.

How to do The Cable Overhead Triceps Extension:

Set a pulley to its highest point (or lower point depending on how it feels for you and your stature) with a rope attachment.
Grab the attachment with both hands and then turn around so you are facing away from the machine.
Stand in a split stance with the attachment behind your head and elbows bent.
Extend your elbows to pull the rope attachment over your head.
Squeeze your triceps at the end of the movement.
Slowly return to the starting position and reset and repeat.

Best rep range: 8-20

Form tips: While in the split stance lower your head and look at the ground. Spreading the rope apart at the end of the movement will add further tension to your triceps.

10. Decline/Incline Bench Cable Triceps Extension (aka Decline/Incline Skull Crusher)

This is a difficult exercise to set up seeing you need an adjustable weight bench, but this variation really hits the triceps hard. Because you are angling your body, you’re increasing the ROM and your arms have further to travel to complete the rep, This means a greater stretch and more muscle-building potential for you.

How to do The Decline Bench Cable Triceps Extension:

Set the cable pulley on its lowest setting with a decline bench a foot in front of it.
Lay back on the decline bench, secure your feet and grab the attachment with both hands.
Straighten the elbows and squeeze the triceps when fully extended.
Bend the elbows to slowly return to the starting position.
Reset and repeat.

Note: For a greater, allow your hands to come behind your head more, this is great for increasing muscle recruitment of the triceps, especially the long head.

Best rep range: 8-12

Form tips: This exercise puts a great stretch on the triceps for more hypertrophy gain, but it is tough on the elbows so let discomfort be your guide.

11. Unilateral Cable Triceps Kickbacks

Unilateral cable triceps kickback is another solid option to further enhance your triceps game. Similar to the dumbbell version but only better because you have constant tensions throughout the ROM. You have the option not to use any attachment here, it’s a matter of personal preference.

How to do The Unilateral Cable Triceps Kickbacks:

Adjust the pulley to its highest point with or without an attachment.
Grab the cable with one hand with your elbow bent and close to your torso and back to create tension.
Then hinge at the hips while resting your non-working hand on your thigh.
Extend your elbow, bringing the hand down and back.
Slowly return to the starting position and reset and repeat.

Best rep range: 8-15

Form tip: If grip strength is an issue better to use an attachment. When you hinge, feel it in your hamstrings and not your back.
