Standing Dumbbell Triceps Extension

Instructions

Stand upright and hold a dumbbell with both hands, positioning it over your head with arms fully extended.
Keep your elbows close to your head as you lower the dumbbell behind your head until your forearms touch your biceps.
Pause briefly at the bottom of the movement and then lift the dumbbell back to the starting position by extending your arms.
Repeat for the recommended number of repetitions.

Flaring elbows out to the sides instead of keeping them close to the head.
Leaning forward or backward, compromising balance and support.
Using excessive weight leading to swinging motion instead of controlled movement.
Not fully extending arms overhead, reducing triceps engagement.
