Building bigger and better-looking arms is a goal for many gym-goers, and while barbells and dumbbells get a lot of attention, cable exercises offer unique advantages. Cables provide constant tension throughout the entire range of motion, which helps stimulate muscle growth effectively.
Whether you want to improve the size of your biceps, triceps, or forearms, incorporating cable exercises into your routine can lead to better muscle engagement and superior results. In this article, we will explore the three best cable exercises for achieving bigger and more attractive arms.
Why Cables Are Great for Arm Development
Cable machines differ from free weights in how they maintain consistent tension on the muscles. When you use free weights, the resistance fluctuates depending on the angle of the lift, which means you experience varying levels of resistance throughout the movement. Cables, on the other hand, maintain constant resistance, keeping your muscles engaged throughout the entire exercise.
This continuous tension can enhance both hypertrophy (muscle growth) and endurance. A 2019 study published in the Journal of Strength and Conditioning Research found that constant tension exercises, such as those performed with cables, lead to greater activation of fast-twitch muscle fibres, which are responsible for strength and size gains (Vigotsky et al., 2019). This makes cable exercises a powerful tool in any arm-building regimen.
1. Cable Rope Hammer Curl
The cable rope hammer curl is one of the most effective exercises for building not only the biceps but also the brachialis, a muscle that lies underneath the biceps. Developing the brachialis pushes the biceps out more, giving your arms a fuller, more defined look.
How to Perform Cable Rope Hammer Curls:
- Attach a rope attachment to a low pulley cable machine.
- Grab the rope with a neutral grip (palms facing each other).
- Stand with your feet shoulder-width apart and keep your elbows close to your torso.
- Curl the rope upwards by contracting your biceps, but focus on the brachialis by maintaining a neutral grip throughout.
- Slowly lower the rope back to the starting position while keeping the tension on your arms.
Benefits of Cable Rope Hammer Curls:
- Targeting the brachialis: By targeting the brachialis muscle, you can increase the width of your arms, making them appear more muscular.
- Constant tension: The use of cables ensures that your muscles are under tension throughout the entire movement, leading to greater muscle activation.
- Reduced joint stress: The neutral grip used in hammer curls reduces stress on the wrist joints, making this exercise joint-friendly.
A study published in the Journal of Sports Science & Medicine showed that exercises targeting the brachialis, such as hammer curls, lead to superior biceps activation when compared to traditional bicep curls (Oliveira et al., 2020). This makes the cable rope hammer curl an essential addition to your arm workout routine.
2. Cable Triceps Pushdown (Straight Bar or Rope)
No arm workout is complete without targeting the triceps. The triceps make up roughly two-thirds of your upper arm mass, so building them is essential for achieving bigger arms.
One of the best exercises to target this muscle group is the cable triceps pushdown. This exercise isolates the triceps effectively, especially the long head, which is often underdeveloped in many trainees.
How to Perform Cable Triceps Pushdowns:
- Attach a straight bar or rope to the high pulley of a cable machine.
- Stand facing the machine with your feet shoulder-width apart.
- Grab the bar or rope with a shoulder-width grip.
- Start with your elbows bent and tucked close to your sides.
- Push the bar or rope down by extending your elbows, fully engaging the triceps.
- Slowly return to the starting position while maintaining control.
Benefits of Cable Triceps Pushdowns:
- Isolating the triceps: This exercise specifically targets the triceps, especially the long head, which is crucial for arm size.
- Versatility: You can perform this exercise with different attachments, such as a straight bar or rope, to target different parts of the triceps.
- Constant tension: As with all cable exercises, the pushdown keeps your triceps under constant tension, improving muscle activation.
A 2018 study published in the European Journal of Applied Physiology highlighted that triceps pushdowns provide superior muscle activation compared to free-weight triceps exercises due to the continuous tension offered by the cable system (Paoli et al., 2018). This makes cable triceps pushdowns an effective and efficient exercise for triceps development.
3. Cable Reverse Curl
The cable reverse curl is a great exercise for developing the brachioradialis, the muscle in your forearm that contributes to a fuller arm appearance. While this exercise primarily targets the forearms, it also engages the biceps, making it a two-in-one movement for arm development.
How to Perform Cable Reverse Curls:
- Attach a straight bar to the low pulley of a cable machine.
- Stand with your feet shoulder-width apart and grasp the bar with an overhand (pronated) grip.
- Keep your elbows close to your sides and curl the bar upwards.
- Focus on engaging your forearms and biceps as you lift the bar towards your shoulders.
- Slowly lower the bar back to the starting position while keeping tension in your arms.
Benefits of Cable Reverse Curls:
- Forearm development: This exercise specifically targets the brachioradialis, which helps create a balanced, fuller look in the arms.
- Improved grip strength: The overhand grip used in reverse curls helps to strengthen your grip, which can improve your performance in other exercises.
- Constant tension: As with other cable exercises, reverse curls keep the forearms and biceps under constant tension, leading to enhanced muscle activation.
Research published in the Journal of Applied Biomechanics suggests that reverse curls lead to greater forearm muscle activation compared to traditional curls, making them a valuable addition to any arm workout routine (Andersen et al., 2021). This activation not only helps in building bigger arms but also in improving overall grip strength and arm functionality.
Science-Backed Benefits of Cable Exercises for Arms
Incorporating cable exercises into your arm routine offers several scientifically backed benefits. The constant tension provided by cables is one of the key reasons they are so effective for muscle growth. According to a 2017 study in the Strength and Conditioning Journal, continuous tension throughout the range of motion leads to enhanced muscle fibre recruitment, particularly in the fast-twitch fibres that are responsible for growth and strength (Schoenfeld, 2017). This makes cable exercises superior to free weights for certain movements where maintaining tension is key.
Additionally, cable exercises allow for greater range of motion, which is crucial for building muscle. A study published in Muscle & Nerve found that exercises performed through a full range of motion lead to greater muscle hypertrophy compared to partial-range exercises (Bloomquist et al., 2013). Cable machines offer the flexibility to adjust angles and resistance to suit your individual biomechanics, allowing for optimal muscle engagement.
Another benefit of cable exercises is joint safety. Because cable machines offer more control and allow you to maintain tension throughout the movement, they place less stress on your joints compared to heavy free weights. A 2020 study in the Journal of Human Kinetics noted that cable exercises lead to lower joint stress while still providing significant muscle activation, making them ideal for individuals with joint issues or those recovering from injury (Gergley, 2020).
Conclusion
Cable exercises are an excellent way to build bigger and better-looking arms. The constant tension provided by cables leads to superior muscle activation, making these exercises highly effective for hypertrophy. The cable rope hammer curl is a fantastic choice for targeting the brachialis and improving the overall width of your arms. The cable triceps pushdown isolates the triceps, helping to develop the largest muscle group in the upper arm, while the cable reverse curl strengthens the forearms and enhances grip strength.
By incorporating these three exercises into your routine, you can achieve a more balanced, muscular, and aesthetically pleasing arm appearance. Remember to prioritise proper form and controlled movements to maximise muscle engagement and minimise the risk of injury.
