The muscle that primarily contributes to the width of your arm is the triceps brachii. It makes up about two-thirds of the upper arm's muscle mass.
- The triceps is located on the back of your arm, extending from your shoulder to your elbow.
- When it contracts, it straightens your arm.
- By developing the triceps, you can increase the overall circumference of your arm, making it appear wider.
Although the biceps (the muscle on the front of your arm) contributes to arm size, it is responsible for arm thickness rather than width.
To further enhance arm width, focus on exercises that target the triceps, such as:
- Close-grip bench press: This exercise targets the triceps while also engaging the chest and shoulders.
- Overhead triceps extensions: This exercise isolates the triceps and allows for a full range of motion.
- Triceps dips: This exercise is a compound movement that works the triceps, chest, and shoulders.
Remember: Consistent training and proper nutrition are crucial for building muscle and increasing arm width.
