Good triceps make you look like a bigger arm,because they have mostly volume in your arm. Mostly people don’t understand this , they focus in biceps for their workout and think that everything on their arms has been changed.The unilateral decline triceps extension is powerful to keep arm bigger. Hold your single dumbbells and hop on decline bench. Try to keep your hand stay after your head with stright with your elbow. Take dumbell up and down in vertical only for best solution.
