Skull Crushers: How To Do, Muscles Worked, Dumbbell vs. Barbell

Skull crushers are a popular triceps exercise that can be done with either dumbbells or a barbell. This exercise is highly effective in building mass in the triceps and shaping the upper arm. There are different variations of skull crushers, including using a straight barbell, E-Z curl bar, or dumbbells. The choice of bar depends on individual goals and limitations. It’s important to find the best option that suits your preferences and allows for optimal performance.

The straight barbell variation of skull crushers allows for a deeper contraction but may cause discomfort in the wrists or elbows. If you experience any discomfort, the E-Z curl bar is a good alternative. Dumbbells, on the other hand, offer a more balanced movement and can help correct strength imbalances between arms.

To perform skull crushers, start by lying on a bench with the weight pressed over your chest. Lower the bar towards your forehead, engaging only the triceps, and then raise it back up. It’s crucial to use appropriate weights and maintain proper form throughout the exercise. The resistance curve of skull crushers is such that the bottom range is the weakest and the top range is the strongest.

The dumbbell skull crusher is another variation that targets the triceps and can help improve lockout strength in pressing movements. To perform this exercise, lie on a bench and hold a dumbbell in each hand. Lower the weights to the sides of your face, and then extend your elbows to raise the weights back up.

Skull crushers provide several benefits, including increased triceps strength and muscle mass, improved lockout strength, better elbow health, and strengthened connective tissues. Whether you’re a strength athlete, regular gym-goer, or looking to build triceps strength and size, skull crushers can be a valuable addition to your workout routine.

To get the most out of your skull crusher workout, it’s essential to use proper form. This exercise primarily targets the triceps, but it also engages other muscles in the upper arms and shoulders. By maintaining correct technique, you can effectively stimulate muscle growth and minimize the risk of injury. Here are some key points to remember when performing skull crushers:

1. Start by lying on a flat bench with your feet planted firmly on the ground. Hold the barbell, E-Z curl bar, or dumbbells with an overhand grip, arms extended, and palms facing towards your feet.
2. Lower the weight towards your forehead by bending your elbows, ensuring that your upper arms remain stationary throughout the movement. It’s important to keep your elbows tucked in and your wrists straight to avoid strain.
3. Avoid locking out your elbows completely at the top of the movement to maintain tension in the triceps. Instead, focus on achieving a controlled contraction.
4. Exhale as you extend your arms back to the starting position, using your triceps to lift the weight. Remember to keep your shoulders stable and your core engaged.

While performing skull crushers, it’s crucial to pay attention to the resistance curve. The bottom portion of the movement is the weakest range, so it’s essential to use appropriate weights that allow you to maintain proper form. Gradually increase the weight as your strength improves.

Muscles Worked in Skull Crushers

Skull crushers primarily target the triceps muscles, which are located on the back of the upper arm. This exercise is known for its ability to isolate and strengthen the triceps, making it a popular choice for individuals looking to improve arm definition and pressing strength.

The triceps brachii muscle is the primary muscle worked during skull crushers, and it consists of three heads: the long head, lateral head, and medial head. The long head is the largest and most visible part of the triceps, contributing to the overall shape and size of the upper arm.

When performing skull crushers, the triceps are responsible for extending the elbow joint and moving the weight against resistance. This exercise helps build strength and muscle mass in the triceps, leading to improved performance in pushing movements such as bench presses, overhead presses, and dips.

Muscle	Primary Function
Triceps brachii (long head)	Elbow extension, shoulder extension
Triceps brachii (lateral head)	Elbow extension
Triceps brachii (medial head)	Elbow extension

By targeting the triceps with skull crushers, individuals can develop stronger and more defined upper arms. This exercise also helps strengthen the connective tissues surrounding the elbow joint, promoting elbow health and reducing the risk of injuries associated with overuse or strain.

To maximize the benefits of skull crushers, it is important to use proper form and choose weights that allow for controlled and smooth movements. Gradually increasing the weight over time can help challenge the muscles and promote further strength gains.

Benefits of Doing Skull Crushers

Adding skull crushers to your workout routine offers a range of benefits for both strength athletes and regular gymgoers. This exercise primarily targets the triceps, helping to build mass and shape the upper arms. By focusing on the triceps muscles, skull crushers can enhance pressing strength and improve lockout ability in movements like bench presses and overhead presses.

One of the advantages of skull crushers is that they promote elbow health and strengthen the connective tissues surrounding the joint. This can be particularly beneficial for individuals who experience discomfort or pain in their elbows during pressing exercises. Performing skull crushers with proper form and gradually increasing the weights can help strengthen the muscles and reduce the risk of injury.

The choice between using a barbell or dumbbells for skull crushers depends on individual goals and limitations. The straight barbell allows for a deeper contraction but may cause discomfort in the wrists or elbows. In contrast, using an E-Z curl bar can be a good alternative for those experiencing discomfort. Dumbbells offer a more balanced movement and can help correct strength imbalances between arms.

To perform skull crushers with dumbbells, lie on a bench and hold a dumbbell in each hand. Lower the weights to the sides of your face, and then extend your elbows to raise the weights back up.
