Triceps are the muscle group that helps extend the elbow forcefully, pulls back the arm and adducts the shoulders, or pulls the arm closer to the body. When the triceps contract isometrically to maintain a specific angle of the elbow, they help with the performance of fine motor movements such as writing, typing or playing a musical instrument. They're also used when we do push-ups, throw a ball, punch a target or gesticulate. The triceps collection has a number of workouts that will help you develop greater control over your triceps and develop better upper body strength.
