dumbbells skull crushers

Dumbbell skull crushers are an effective isolation exercise primarily targeting the triceps muscles. They work all three heads of the triceps simultaneously (medial, lateral, and long heads), promoting balanced arm development and strength. This exercise also helps improve shoulder mobility and stability, important for everyday movements like lifting and pushing. To perform dumbbell skull crushers, you lie back on a bench with a dumbbell in each hand held above your head, then bend your elbows to lower the dumbbells toward the sides of your head before extending your arms back to the starting position. Using dumbbells allows each arm to work independently, helping to correct strength imbalances. Among the benefits are increased triceps strength for daily functional activities, enhanced arm definition, and better shoulder mobility. Dumbbell skull crushers can be included in upper body or arm workouts, typically with 4 sets of 10-12 reps using a controlled motion for best results. Variations include using EZ bars, cable machines, or a straight bar for different grips and tension.
