Triceps Training: How to Effectively Target All Three Heads

How to Hit All Tricep Heads?

To comprehensively target all three heads of the triceps brachii—the long, lateral, and medial heads—it is essential to understand their individual anatomical functions and select a variety of exercises that manipulate arm position relative to the torso, particularly focusing on movements that involve both elbow extension and shoulder extension/adduction.

Understanding Triceps Anatomy

The triceps brachii, meaning "three-headed arm muscle," is the primary muscle on the posterior aspect of the upper arm. Its main function is elbow extension, straightening the arm. However, each head has a slightly different origin, which influences how it's best activated:

• Long Head: Originates from the infraglenoid tubercle of the scapula (shoulder blade). Because it crosses the shoulder joint, it assists in both shoulder extension (bringing the arm down from an overhead position) and adduction (bringing the arm towards the body). This head contributes significantly to overall triceps mass and length.
• Lateral Head: Originates from the posterior surface of the humerus, superior to the radial groove. This head is largely responsible for the "horseshoe" shape of the triceps and is highly visible when well-developed. It primarily acts on elbow extension.
• Medial Head: Originates from the posterior surface of the humerus, inferior to the radial groove. This head lies deep to the long and lateral heads and is active in nearly all elbow extension movements, particularly at the beginning and end of the range of motion. It is often considered the "workhorse" of the triceps.

Targeted Training Principles

To effectively stimulate all three heads, your training strategy must account for their unique biomechanical roles:

• Vary Arm Position: Changing the angle of your upper arm relative to your torso shifts emphasis among the triceps heads.
• Incorporate Shoulder Movement: Exercises that involve shoulder extension or adduction will place greater emphasis on the long head.
• Full Range of Motion: Ensure exercises are performed through their complete range to maximize muscle fiber recruitment.
• Controlled Execution: Focus on the mind-muscle connection, ensuring the triceps are doing the work, not momentum or other muscle groups.

Exercises for Comprehensive Triceps Development

While all triceps exercises engage all three heads to some degree, certain movements allow for greater emphasis on specific heads due to the arm and shoulder joint positions.

Emphasizing the Long Head

The long head is best targeted with exercises where the arm is overhead or where there is significant shoulder extension/adduction.

• Overhead Dumbbell/Cable Triceps Extensions: Performing extensions with the arms overhead places the long head in a stretched position, requiring it to work harder.
  • Execution: Sit or stand with a dumbbell held with both hands or a rope attachment from a low pulley. Extend your arms overhead, keeping elbows pointed forward. Slowly lower the weight behind your head by flexing the elbows, then powerfully extend back up.
• Close-Grip Bench Press (with Elbows Tucked): While a compound movement for the chest, keeping the grip close and elbows tucked significantly increases triceps activation, particularly the long head due to the shoulder adduction component.
  • Execution: Lie on a bench, grip the barbell with hands shoulder-width apart or slightly narrower. Lower the bar to your lower chest/upper abdomen, keeping elbows tucked close to your sides. Press the bar back up, squeezing the triceps at the top.
• Rope Triceps Pushdowns (Elbows Back): When performed with the elbows kept relatively stationary and slightly behind the body, this can emphasize the long head.
  • Execution: Stand facing a cable machine with a rope attachment. Keep your elbows tucked close to your sides and slightly behind your torso. Extend your forearms downwards, pulling the rope apart at the bottom.

Emphasizing the Lateral Head

The lateral head is often highly active in standard elbow extension movements, especially when the arms are close to the body or slightly flared.

• Straight Bar/V-Bar Triceps Pushdowns: A staple for triceps development, these allow for strong contraction of the lateral head.
  • Execution: Stand facing a cable machine with a straight or V-bar attachment. Keep your elbows tucked to your sides. Press the bar down until your arms are fully extended, squeezing your triceps. Control the ascent.
• Dumbbell Kickbacks: While controversial for heavy loading, if performed with strict form, kickbacks can isolate the lateral head.
  • Execution: Hinge at the hips, keeping your back straight and core engaged. Hold a dumbbell in each hand, upper arms parallel to the floor. Extend your forearms straight back, squeezing the triceps at the top.
• Dips (Triceps Emphasis): Lean forward slightly, keep your body upright, and tuck your elbows in to maximize triceps activation.
  • Execution: Use parallel bars or a dip machine. Lower your body by bending your elbows, keeping them tucked. Push back up by extending your arms.

Emphasizing the Medial Head

The medial head is active in virtually all triceps movements, but its contribution is particularly significant in the latter stages of elbow extension and when the forearms are pronated or supinated.

• Reverse-Grip Triceps Pushdowns: Using an underhand grip can shift some emphasis to the medial head, particularly as it works through a slightly different angle.
  • Execution: Use a straight bar or EZ bar on a cable machine. Grip with an underhand (supinated) grip. Keep elbows tucked and press down, focusing on the contraction.
• Close-Grip Push-ups: Similar to close-grip bench press, but bodyweight. Keeping hands close together and elbows tucked emphasizes the triceps.
  • Execution: Start in a push-up position with hands directly under your chest, fingers pointing forward. Lower your chest towards the floor, keeping elbows tucked close to your body. Push back up.

Structuring Your Triceps Workout

For comprehensive triceps development, aim to include at least one exercise that emphasizes the long head (e.g., overhead extension) and one or two exercises that target the lateral/medial heads (e.g., pushdowns, dips).

Example Triceps Workout:

1. Overhead Dumbbell Triceps Extensions: 3-4 sets of 8-12 reps (Long Head focus)
2. Straight Bar Triceps Pushdowns: 3-4 sets of 10-15 reps (Lateral/Medial Head focus)
3. Dips (Bodyweight or Machine): 3 sets to failure or 8-12 reps (Overall Triceps, good for Lateral/Medial)
4. Rope Triceps Pushdowns (Elbows Back or Rope Apart): 2-3 sets of 12-15 reps (Versatile, can target long or lateral depending on form)

Key Considerations for Optimal Growth

• Progressive Overload: To ensure continuous growth, consistently challenge your triceps by gradually increasing resistance, reps, sets, or decreasing rest times over weeks and months.
• Form Over Weight: Sacrificing proper form for heavier weight will not effectively target the triceps heads and increases injury risk. Focus on controlled movements and feeling the muscle work.
• Mind-Muscle Connection: Actively think about squeezing your triceps during each repetition. This helps recruit more muscle fibers.
• Nutrition and Recovery: Adequate protein intake, sufficient calories, and quality sleep are crucial for muscle repair and growth.

By understanding the unique contributions of each triceps head and strategically selecting exercises that target them through varied arm and shoulder positions, you can achieve comprehensive and balanced triceps development.
