One of the most commonly used triceps exercises in just about every gym in the world (not without good reason), skull crushers will tone and/or add mass to your arms. I recommend working within 6 to 12 reps for size, or 12+ reps for toning, but don’t expect to burn fat from the back of your arms by doing triceps exercises. It doesn’t work like that, unfortunately. Weight loss is done through maintaining a healthy diet!
