The triceps is a large muscle located at the back of your upper arm. It is responsible for extending the elbow, which means it helps straighten your arm. The name "triceps" comes from the Latin word for "three heads," referring to its three distinct muscle bundles. Strong triceps are important for various activities, from pushing movements like push-ups to lifting heavy objects. To strengthen your triceps, you can perform exercises such as tricep dips or overhead tricep extensions. These workouts not only improve arm strength but also enhance overall upper body performance. A well-developed triceps can contribute to better athletic performance and a more toned appearance.
