Triceps Extensions (Single-Arm) is an exercise that targets the triceps muscles. To perform this exercise, you will need a dumbbell and a bench. Here are the steps:
Hold a dumbbell in one hand and raise it above your head with your arm fully extended.
Keep your upper arm close to your head and slowly lower the dumbbell behind your head, keeping your elbow stationary and only moving your forearm.
Once your forearm reaches parallel to the ground, raise the dumbbell back to the starting position.
Repeat for the desired number of repetitions, then switch to the other arm.
Engage your core and maintain proper form throughout the exercise.
