Triceps brachii, commonly known as triceps, are a group of three muscles located on the posterior aspect of the upper arm. They are responsible for extending the elbow joint and are commonly targeted in weight-training exercises. While dumbbells are a popular choice for triceps exercises, there are many other effective ways to work this muscle group without them.
Bodyweight exercises, such as dips, push-ups, and triceps extensions, can be very effective in building triceps strength and mass. Resistance bands and suspension trainers can also be used to perform a variety of triceps exercises. Additionally, there are many machines at most gyms that can be used to target the triceps.
