What is One Arm Supinated Dumbbell Triceps Extension? One arm supinated dumbbell triceps extension is an isolation exercise that targets the triceps muscles. By using a supinated (underhand) grip with a dumbbell, this exercise places emphasis on the long head of the triceps, helping to build strength and size in this muscle group.
Tutorial
- Starting Position:
-
Stand or sit on a bench with your back straight.
-
Hold a dumbbell in one hand with an underhand grip, palm facing up. - Extend your arm straight up above your head. 2. Execution: - Lower the dumbbell behind your head by bending your elbow.
-
Keep your upper arm stationary and close to your head throughout the movement. - Extend your arm back to the starting position by straightening your elbow. 3. Repetitions: - Aim for 3-4 sets of 10-15 repetitions on each arm.
Common Mistakes
-
Arching the back: Keep your back straight to avoid strain and maintain proper form.
-
Using momentum: Control the movement throughout the exercise to fully engage the triceps. - Not lowering the weight enough: Ensure the dumbbell goes behind your head to engage the triceps effectively.
Tips for Better Results
-
Use a controlled tempo: Focus on the eccentric (lowering) phase to maximize muscle engagement.
-
Engage your core: Maintain core stability to support your back and overall posture. - Choose an appropriate weight: Start with a lighter weight to master form before progressing to heavier weights.
