Tricep Dumbbell Kickbacks target the triceps by extending the arms backward while keeping the upper arms stationary. Hold a dumbbell in each hand, hinge slightly at the hips, and keep your elbows close to your torso. Extend your forearms fully behind you, then return slowly to the starting position. This controlled movement builds tricep strength, improves muscle definition, and enhances arm endurance while emphasizing proper form and joint safety.
