The barbell skull crusher, also known as the barbell lying triceps extension, is a popular and effective exercise for targeting the triceps muscles. This exercise is performed by lying on a bench and extending the arms to lower a barbell towards the forehead (hence the name "skull crusher") before extending the arms back to the starting position. It is a key movement for building strength and size in the triceps and is often included in upper body workout routines.
Benefits of the Barbell Skull Crusher:
-
Triceps Development: The primary benefit of the barbell skull crusher is its focus on the triceps. By isolating the triceps, this exercise helps build muscle mass and strength in the upper arms, making it an essential part of any triceps training programme.
-
Improves Arm Strength: Regularly performing skull crushers helps increase the strength of the triceps, which can improve performance in other compound lifts that rely on tricep strength, such as the bench press, overhead press, and push-ups.
-
Enhanced Muscle Definition: For those looking to define the arms and achieve a more sculpted look, the skull crusher is an excellent exercise. By targeting the long head of the triceps, which is often underdeveloped, it helps create a more balanced and defined appearance in the upper arms.
-
Isolation Movement: Unlike compound exercises such as the bench press or push-ups, the skull crusher is an isolation movement that specifically targets the triceps. This allows for more focused muscle engagement and is ideal for those looking to build muscle in the arms.
-
Improves Elbow Stability: The movement helps improve the stability of the elbow joint by strengthening the muscles around it, which can contribute to better performance and injury prevention during other upper body exercises.
-
Variety in Training: Incorporating the skull crusher into your workout routine adds variety to your triceps training. It can be used to break through plateaus and stimulate muscle growth in a different way compared to other triceps exercises.
Form of the Barbell Skull Crusher:
-
Starting Position:
- Begin by setting up a flat bench and loading an appropriate weight onto a barbell. Ideally, have a spotter nearby when using heavy weights to ensure safety.
- Lie flat on the bench with your feet firmly planted on the ground. Your head, back, and hips should be in contact with the bench, and your arms should be fully extended, holding the barbell with an overhand (pronated) grip, with your hands about shoulder-width apart.
-
Grip:
- Take a firm grip of the barbell with your palms facing upwards (overhand grip). Your hands should be positioned so that the bar is directly over your chest in the starting position, with your elbows slightly bent to avoid locking them out.
-
Lowering the Barbell:
- Keeping your upper arms stationary and perpendicular to the floor, slowly lower the barbell towards your forehead (or just behind it for a deeper stretch, depending on your flexibility). Focus on using your triceps to control the movement, not your shoulders or wrists.
- As you lower the bar, keep your elbows tucked in (not flaring out), ensuring that the movement is being driven by your forearms, not your upper arms.
-
Extending the Arms:
- Once the barbell reaches the desired point (near your forehead), pause briefly, and then push the bar back up by extending your elbows. Be sure to extend your arms fully at the top of the movement to engage the triceps fully.
- Keep your elbows in place and avoid letting them flare outwards during the extension phase. The movement should be smooth and controlled.
-
Breathing:
- Inhale as you lower the barbell towards your forehead, and exhale as you push the barbell back up. Proper breathing helps maintain control and supports the effort required to complete each repetition.
-
Repetitions and Sets:
- Aim for 3-4 sets of 8-12 repetitions, depending on your goals. For strength, use heavier weights with fewer reps (e.g., 4-6), while for muscle growth (hypertrophy), moderate weights with higher reps (8-12) are typically recommended.
Safety Tips:
- Control the Weight: Never let the weight drop too quickly during the lowering phase. Always control the barbell throughout the entire movement to avoid unnecessary strain on the elbows and wrists.
- Elbow Position: Keep your elbows slightly bent throughout the movement. Avoid locking your elbows out at the top to reduce the risk of hyperextension.
- Proper Grip: Ensure your grip is secure and that your hands are placed correctly to prevent the bar from slipping. If you're using heavy weights, a spotter can help ensure safety.
- Avoid Overextending: While it’s important to get a full range of motion, do not overextend your arms at the top of the movement. Hyperextending your elbows can cause strain on the joint.
In summary, the barbell skull crusher is an excellent exercise for developing and defining the triceps. By following proper form and focusing on controlled movements, it can help you build muscle and improve strength in the arms. Whether you’re looking to enhance your triceps development or add variety to your upper body workouts, the barbell skull crusher is a valuable addition to any training routine.
