10 Best Cable Concentration Extension (on Knee) Alternatives for Home & Rehab
If you can’t perform the Cable Concentration Extension (on Knee), use exercises that maintain isolated elbow extension and unilateral control. Good substitutes include single-arm cable overhead extensions, one-arm dumbbell kickbacks, diamond push-ups, bench dips, and skull crushers. Cue: keep your upper arm stationary and drive only at the elbow to maximize triceps activation.

1. Cable One Arm Tricep Extension
89.9% MatchHow to perform this exercise
- With your right hand, grasp a single handle attached to the high-cable pulley using a supinated (underhand; palms facing up) grip. You should be standing directly in front of the weight stack.
- Now pull the handle down so that your upper arm and elbow are locked in to the side of your body. Your upper arm and forearm should form an acute angle (less than 90-degrees). You can keep the other arm by the waist and you can have one leg in front of you and the other one back for better balance. This will be your starting position.
- As you contract the triceps, move the single handle attachment down to your side until your arm is straight. Breathe out as you perform this movement. Tip: Only the forearms should move. Your upper arms should remain stationary at all times.
- Squeeze the triceps and hold for a second in this contracted position.
- Slowly return the handle to the starting position.
2. Cable Standing One Arm Triceps Extension
85.9% MatchHow to perform this exercise
- Stand with your feet shoulder-width apart, facing the cable machine.
- Hold the cable handle with your right hand, palm facing down, and position your arm so that it is fully extended and parallel to the ground.
- Keep your elbow stationary and close to your body.
- Slowly bend your elbow, lowering the cable handle towards the back of your head.

- Pause for a moment at the bottom, then push through your hands to straighten your arms and return to the starting position.
4. Cable Kickback
80.9% MatchHow to perform this exercise
- Stand facing a cable machine with your feet shoulder-width apart.
- Hold the cable handle with your right hand and step back to create tension in the cable.
- Bend your knees slightly and hinge forward at the hips, keeping your back straight.
- Keep your upper arm close to your body and your elbow bent at a 90-degree angle.
- Extend your forearm backward, straightening your arm fully.
5. Chain Handle Extension
80.4% MatchHow to perform this exercise
- You will need two cable handle attachments and a flat bench, as well as chains, for this exercise. Clip the middle of the chains to the handles, and position yourself on the flat bench. Your elbows should be pointing straight up.
- Begin by extending through the elbow, keeping your upper arm still, with your wrists pronated.
- Pause at the lockout, and reverse the motion to return to the starting position.
6. Cable Rope Incline Tricep Extension
78.9% MatchHow to perform this exercise
- Attach a rope to a high pulley and adjust the incline bench to a comfortable angle.
- Stand facing away from the pulley with your feet shoulder-width apart.
- Grasp the rope with an overhand grip and extend your arms straight overhead.
- Keep your elbows close to your head and your upper arms stationary throughout the exercise.
- Lower the rope behind your head by bending your elbows until your forearms touch your biceps.
7. Cable Rear Drive
78.4% MatchHow to perform this exercise
- Attach a handle to a low pulley cable machine and stand facing away from the machine.
- Grasp the handle with an overhand grip and extend your arms straight out in front of you.
- Keeping your elbows stationary, pull the handle back towards your body, squeezing your triceps at the end of the movement.
- Slowly return the handle to the starting position and repeat for the desired number of repetitions.
8. Cable Alternate Triceps Extension
78.1% MatchHow to perform this exercise
- Stand facing the cable machine with your feet shoulder-width apart.
- Hold the cable handle with your right hand and bring your arm up so that your upper arm is parallel to the ground and your elbow is bent at a 90-degree angle.
- Keep your upper arm stationary and extend your forearm backward, fully straightening your arm.
- Pause for a moment, then slowly return to the starting position.
- Repeat with your left arm.
9. Cable Lying Triceps Extension
78.1% MatchHow to perform this exercise
- Lie on a flat bench and grasp the straight bar attachment of a low pulley with a narrow overhand grip. Tip: The easiest way to do this is to have someone hand you the bar as you lay down.
- With your arms extended, position the bar over your torso. Your arms and your torso should create a 90-degree angle. This will be your starting position.
- Lower the bar by bending at the elbow while keeping the upper arms stationary and elbows in. Go down until the bar lightly touches your forehead. Breathe in as you perform this portion of the movement.
- Flex the triceps as you lift the bar back to its starting position. Exhale as you perform this portion of the movement.
- Hold for a second at the contracted position and repeat for the recommended amount of repetitions.

- Pause for a moment, then slowly extend your arms back out to the starting position.
- Repeat for the desired number of repetitions.
Why You Might Need a Cable Concentration Extension (on Knee) Alternative
You might swap this exercise because you lack a cable station, have knee discomfort from the kneeling position, or need a greater loading option for hypertrophy. Rehabilitation protocols and unilateral imbalances also drive substitutions. Choose movements that still isolate elbow extension—this preserves lateral and medial head recruitment—while adjusting shoulder position to reduce long-head strain. For example, an overhead dumbbell extension increases long-head length tension; a kickback emphasizes lateral-head peak contraction. Keep the elbow fixed and control the eccentric to protect joints and sustain triceps loading.
How to Choose the Right Substitute
Select a substitute based on equipment, desired muscle emphasis, and stability needs. If you want long-head stretch and heavier load, pick overhead extensions and cue a vertical forearm path with a slight shoulder flexion. For strict isolation with minimal shoulder involvement, choose kickbacks or cable pushdowns and keep the upper arm rigid. For rehab or home use, use bands or bodyweight (diamond push-ups) and focus on slow eccentrics to preserve tension. Prioritize exercises that allow progressive overload and let you maintain full elbow extension range of motion.
Frequently Asked Questions
What muscles does Cable Concentration Extension (on Knee) work?
It primarily targets the triceps brachii—lateral and medial heads for elbow extension and the long head when the shoulder is extended. Keep your elbow anchored and extend only at the elbow to isolate the triceps while the core and shoulder stabilizers resist rotation.
What is the best bodyweight alternative to Cable Concentration Extension (on Knee)?
Diamond push-ups are the best bodyweight substitute for triceps isolation; place hands close beneath the sternum and keep elbows tight. Cue a straight forearm path and controlled eccentric to maximize triceps activation while minimizing shoulder involvement.
Can I build muscle without doing Cable Concentration Extension (on Knee)?
Yes. You can achieve hypertrophy with other isolation and compound movements that load elbow extension, such as skull crushers, dips, and weighted pushdowns. Focus on progressive overload, full elbow extension, and slow eccentrics to stimulate triceps growth.
