One-Arm Dumbbell Triceps Extension
The one-arm dumbbell triceps extension is an effective exercise for isolating and strengthening your triceps. This exercise offers the unique benefit of allowing you to train each arm separately, which helps correct muscle imbalances.
Execution
-
1
Begin by choosing a suitable dumbbell and sit on a bench or stand with your feet shoulder-width apart.
-
2
Hold the dumbbell in one hand and raise your arm so it is straight above your shoulder. Your elbow should point toward the ceiling, with your arm almost fully extended.
-
3
Inhale and slowly bend your elbow to lower the dumbbell behind your head. Make sure that only your forearm moves.
-
4
Exhale and use your triceps to bring the dumbbell back to the starting position.
-
5
Repeat the movement for the desired number of repetitions, then switch arms.
Benefits
- Improves symmetry between both arms.
- Increases focus and isolation on the triceps.
- Can help improve overall arm strength and shape.
Common Mistakes
- ! Performing the exercise too quickly, which can lead to less effective muscle activation and an increased risk of injury.
- ! Using weights that are too heavy, causing technique to deteriorate.
- ! Not fully extending the arm at the end of the movement, which reduces the effectiveness of the exercise.
Primary Muscles
The primary muscle group trained with this exercise is the triceps brachii. The forearms are also lightly engaged for stability.
Possible Alternatives
- Triceps dips: For an exercise that uses more body weight.
- Two-Arm Overhead Triceps Extension: For when you want to train both arms simultaneously.
- Cable Triceps Pushdown: For constant resistance throughout the movement.
