Overhead One Arm Dumbbell Triceps Extension Download the app: https://mytraining.pro/ Read our community blog: http://friends.mytraining.pro/ (Starting Position) – While standing up or sitting on a flat bench with back support, grab a dumbbell with one hand. – Then, lift the weight and hold it directly behind your neck with your elbow bent and pointing up, and your upper arm close to your head. – The palm gripping the dumbbell should be facing forward. This is the starting position. (First Movement) Now, exhale as you use your triceps to push the dumbbell up until your arm is extended. (Second Movement) Hold the contraction for a moment, and then inhale as you slowly lower the weight back to the starting position. (General Tips) Only your forearm should move during this exercise, so be sure to keep the rest of your body stationary. When you finish your reps on that arm, switch sides and perform the same number of reps with the other arm.
