Single Arm Dumbbell Overhead Tricep Extension
- Hold a dumbbell handle vertically with one hand, gripping it at the top of its “neck” so the base of your thumb is pressed against the weight, and raise it overhead like in the video.
- Let the dumbbell lower overhead naturally as low as possible, press back overhead until your arm fully straightens.
- Your forearm should firmly press into your bicep at the bottom part of each rep, and the bottom part of the dumbbell should touch the back of your shoulder.
- Allow your elbow to flare outward or inward, whichever is most comfortable. What matters is keeping your elbow pointed upward as high as possible.
