The Dumbbell Seated Triceps Extension is a classic strength-training exercise that targets the triceps, the muscles responsible for extending the elbows and making up the majority of the upper arm. This exercise is a favorite among lifters because it promotes muscle isolation, builds strength, and enhances arm definition. Whether you’re a beginner or an advanced lifter, the Dumbbell Seated Triceps Extension is an excellent addition to any upper-body routine.
Introduction
Building strong and well-defined triceps is crucial for overall upper-body strength and aesthetics. The Dumbbell Seated Triceps Extension emphasizes the long head of the triceps, which is often underutilized in other exercises. By performing this movement in a seated position, you eliminate the need for balance, allowing you to focus entirely on form and muscle engagement.
