The triceps is a muscle that makes up most of the upper arm mass and consists of three segments, or heads. When developed and defined, these three muscles form a distinctive inverted V shape that runs from the back of the shoulder to the elbow along the back of the arm. This shape is often referred to as the horseshoe and is considered a tell-tale sign of an intense workout routine.

What You'll Learn
The triceps make up most of the upper arm mass
The triceps is a large muscle on the back of the upper arm in many vertebrates, including humans. It is an extensor muscle of the elbow joint and an antagonist of the biceps and brachialis muscles. The triceps, also known as the triceps brachii, has three parts or heads: the long head, the lateral head, and the medial head. The long head is the largest of the three. The triceps is responsible for extending the forearm at the elbow joint, opposing the action of flexors such as the biceps brachii. It can also fixate the elbow joint when the forearm and hand are used for fine movements, such as writing.
The triceps are active anytime the elbow is straightened. The incline press, flat bench press, and overhead press all work the triceps in almost exactly the same way. For the best development of the triceps, it is recommended to choose a variety of exercises where the upper arm is in a different position relative to the trunk: overhead, behind you, and in front of you. For example, one exercise involves holding a single dumbbell overhead, keeping your elbows close to your ears, your face forward, and your neck upright, and then bending your arms until you feel a deep stretch in your triceps.
The head that is most responsible for the horseshoe shape is the lateral head, which is located on the outward-facing side of the humerus. The long head is located along the bottom side of the humerus, and the medial head lies deeper than the other two, covered by them. The long head has a secondary function of assisting the Latissimus Dorsi in adduction of the arm (bringing the arm down toward the body). Working the triceps when the long head is neither stretched nor fully contracted allows it to handle more weight, adding another dimension for development.

The lateral head is responsible for the horseshoe shape
The triceps muscle, located at the back of the upper arm, is made up of three segments, or heads: the lateral head, the medial head, and the long head. The lateral head is located on the outward-facing side of the humerus, running from the back of the shoulder down to the elbow. When well-developed and defined, this lateral head forms a horseshoe, or croissant, shape.
To target the lateral head and enhance the horseshoe shape, specific exercises can be performed. One such exercise is the cable pressdown, which is a popular choice in triceps programs. Additionally, movements with thumbs pointing up, such as rope extensions, will emphasize the outer head and contribute to the horseshoe appearance. It is important to vary the angles and positions of exercises to stimulate muscle growth and development.
The triceps muscle, as its name suggests, has three heads that work together to extend the elbow and straighten the arm. The lateral head, being on the outside of the arm, plays a crucial role in creating the horseshoe shape when viewed from the back. By training the triceps from different angles and using various movements, individuals can effectively develop the lateral head and accentuate the horseshoe appearance.
In summary, the lateral head of the triceps muscle is primarily responsible for the horseshoe shape. This shape is aesthetically pleasing and indicative of well-developed arm muscles. By incorporating specific exercises and variations into a training routine, individuals can effectively target the lateral head and enhance the horseshoe appearance of their triceps.

The long head is the largest of the three heads
The horseshoe muscle is a reference to the triceps brachii, a muscle that makes up most of the upper arm mass. The triceps, as the name suggests, has three heads: the lateral head, the medial head, and the long head. The long head is the largest of the three heads and is located along the bottom side of the humerus. When a person stands with their arms hanging down, the long head is the section of the muscle closest to their side.
The long head of the triceps originates from the scapula (shoulder blade) and attaches to the humerus. It is responsible for assisting in the action of pushing the upper arm backward and behind the body. For example, when a person pushes themselves forward with ski poles, the long head of the triceps is actively engaged. Additionally, the long head has a secondary function of assisting the latissimus dorsi muscle in adduction of the arm, which involves bringing the arm down toward the body.
The long head of the triceps can be effectively targeted through various exercises. One such exercise is the French press, where an individual stands or sits with a weight directly overhead and lowers it in a controlled manner for a deep stretch. It is important to keep the elbows pointing up and not angled excessively to the sides. Another exercise is the skullcrusher, where a person lies on a flat bench and extends a weight directly over their upper body with locked arms.
To isolate the long head of the triceps, a specific position can be assumed where the individual lies on their back with their arms extended toward the ceiling. In this position, the long head is neither stretched nor fully contracted, allowing it to handle more weight and facilitating its development. Overhead movements, such as triceps extensions, are also recommended by experts to effectively work the long head.
Overall, the long head of the triceps plays a crucial role in upper arm movement and can be targeted through specific exercises to promote muscle growth and strength. By incorporating a variety of exercises and angles into a workout routine, individuals can effectively develop the long head and achieve well-defined horseshoe-shaped triceps.

The medial head is located towards the body's midline
The horseshoe muscle is a reference to the triceps brachii, a muscle that makes up most of the upper arm mass. The triceps consist of three segments, or heads: the lateral head, the medial head, and the long head. The medial head is located towards the midline of the body.
The medial head runs from the back of the upper arm, close to the shoulder joint, down to the elbow. Parts of the medial head are obscured by the lateral and long heads. However, the lower portion of the muscle can be seen and felt just above the middle of the elbow on the back of the arm.
While the lateral head is most responsible for the horseshoe shape, the medial head is also involved in creating this distinctive look. The medial head's position towards the body's midline contributes to the overall shape and appearance of the triceps.
To effectively target the medial head, various exercises can be performed. For example, tricep extensions and cable pressdowns can isolate the triceps and stress the medial head fibres. Additionally, exercises such as French presses, skullcrushers, and dumbbell extensions can also be incorporated to work the triceps from different angles and promote overall development.
By focusing on the medial head and incorporating a variety of exercises, individuals can enhance the horseshoe shape of their triceps and achieve their desired aesthetic goals.

Exercises for building horseshoe triceps
The horseshoe muscle, or the triceps brachii, is a large muscle at the back of the upper arm that straightens the elbow joint and is important in pushing movements. It is desirable to bodybuilders and fitness enthusiasts due to its distinct shape, which resembles a horseshoe when fully developed and can be seen under the skin of the upper arm. This muscle is often targeted by those wanting to increase upper body strength and improve the aesthetic appearance of their arms. Here are some exercises to build and strengthen the horseshoe triceps:
Close-Grip Bench Press: This exercise is a compound movement that primarily targets the triceps while also working the shoulders and chest. By using a closer grip (approximately 12-15 inches wide), the emphasis is shifted more onto the triceps. Lie on a flat bench with a barbell directly on top, hands shoulder-width apart or slightly narrower, and lower the bar to your chest before pressing it back up, keeping your elbows tucked in.
Tricep Pushdown: This isolation exercise uses a cable machine or resistance bands and works the triceps through a pushing motion. Attach a straight bar or rope handle to a high pulley, stand facing the machine, and pull the bar down until your elbows are at your side, keeping your elbows tucked into your body. Push the bar back up until your arms are fully extended, and repeat.
Skull Crushers: Also known as lying triceps extensions, this exercise isolates the triceps and can be performed with a barbell, EZ-bar, or dumbbells. Lie on a flat bench with the weight directly on top, and lower it toward your forehead while keeping your elbows up and tucked in. Then, extend your arms back up without locking your elbows. This movement works the triceps through a full range of motion.
Dips: Bodyweight dips are a compound exercise that work multiple muscle groups, including the triceps, shoulders, and chest. Using dip bars or parallel bars, lower yourself down until your elbows are at a 90-degree angle, and then push back up through your palms, keeping your body straight. For an increased challenge, add weight by wearing a weighted vest or holding a dumbbell between your feet.
Kickbacks: This isolation exercise targets the triceps and can be performed with a cable machine or dumbbells. For cable kickbacks, attach a single handle to a low pulley and kneel on a pad facing the machine. Keep your upper arm tucked into your side and parallel to the floor, and extend your arm back until it is straight, then return to the starting position. Dumbbell kickbacks can be performed in a similar fashion, kneeling on a bench and using one dumbbell at a time.
These exercises, when incorporated into a well-rounded training program and combined with proper nutrition and recovery, can effectively build and define the horseshoe triceps. Remember to allow for adequate rest and recovery between workouts to promote muscle growth and repair.
