Triceps Training: Anatomy, Key Exercises, Proper Form, and Programming

How to properly do triceps?

Proper triceps training involves a comprehensive understanding of their anatomy, selecting exercises that target all three heads effectively, and executing them with precise form, controlled movement, and progressive overload to maximize strength and hypertrophy while minimizing the risk of injury.

Understanding the Triceps Brachii

The triceps brachii, meaning "three-headed arm muscle," is the primary muscle on the posterior aspect of the upper arm. It comprises three distinct heads, each with unique origins but sharing a common insertion point on the olecranon process of the ulna:

• Long Head: Originates from the infraglenoid tubercle of the scapula. Due to its scapular origin, it is the only head that crosses both the shoulder and elbow joints, making it active in both elbow extension and shoulder extension/adduction.
• Lateral Head: Originates from the posterior surface of the humerus, superior to the radial groove. It is most visible and contributes significantly to the "horseshoe" shape of the triceps.
• Medial Head: Originates from the posterior surface of the humerus, inferior to the radial groove. This head is often considered the "workhorse" of the triceps, being active in nearly all elbow extension movements and remaining active even with light loads.

Primary Function: The overarching function of all three heads is elbow extension, straightening the arm. The long head also assists in shoulder extension and adduction, pulling the arm down and back towards the body.

Principles of Effective Triceps Training

To optimize triceps development and function, adhere to these fundamental exercise science principles:

• Full Range of Motion (ROM): Performing exercises through their complete anatomical range ensures maximal muscle fiber recruitment and promotes greater flexibility and joint health. For triceps, this typically means fully flexing the elbow at the bottom and fully extending it at the top, without locking the joint excessively.
• Mind-Muscle Connection (MMC): Actively focusing on contracting the triceps during the movement, rather than just moving the weight, enhances neural drive to the target muscle, potentially improving hypertrophy.
• Progressive Overload: To continually stimulate muscle growth and strength, you must gradually increase the demands placed on the triceps over time. This can be achieved by increasing weight, reps, sets, decreasing rest time, or improving exercise form.
• Variety: While foundational exercises are crucial, incorporating a variety of movements that target the triceps from different angles and with varying resistance profiles can ensure comprehensive development of all three heads.
• Proper Warm-up and Cool-down: Begin each session with light cardio and dynamic stretches to prepare the joints and muscles. Conclude with static stretches to improve flexibility and aid recovery.

Key Triceps Exercises and Proper Form

Here are several effective exercises for training the triceps, along with detailed form instructions:

Close-Grip Bench Press

This compound exercise is excellent for overall triceps mass and strength, particularly engaging the lateral and medial heads, with significant involvement from the chest and shoulders.

• Starting Position: Lie on a flat bench with your feet firmly on the floor. Grip the barbell with an overhand grip, hands slightly narrower than shoulder-width apart (typically 1-2 hand-widths inside your normal bench press grip). Unrack the bar directly over your chest.
• Execution:
  1. Lower the bar slowly and in a controlled manner towards your lower chest/upper abdomen, keeping your elbows tucked close to your body (they should track backwards, not flare out).
  2. Pause briefly at the bottom, feeling a stretch in your triceps.
  3. Press the bar back up to the starting position by extending your elbows, focusing on driving through your triceps.
  4. Avoid locking out your elbows forcefully at the top; maintain tension.
• Key Cues: Keep elbows tucked, control the descent, squeeze triceps at the top.

Overhead Triceps Extension (Dumbbell or Cable)

This exercise effectively stretches and activates the long head of the triceps due to its position in shoulder flexion.

• Starting Position:
  • Dumbbell: Stand or sit with a dumbbell held in both hands, palms facing each other, extended directly overhead. Keep your core tight and back straight.
  • Cable: Stand facing away from a high cable pulley, holding a rope attachment with both hands, arms extended overhead.
• Execution:
  1. Slowly lower the weight behind your head by flexing your elbows, keeping your upper arms stationary and close to your ears. You should feel a deep stretch in the long head of your triceps.
  2. Pause when your forearms are roughly parallel to the floor or slightly lower.
  3. Extend your elbows to press the weight back overhead, focusing on contracting your triceps to straighten your arms.
• Key Cues: Keep elbows pointed forward/up, avoid flaring elbows, control the eccentric phase, minimize shoulder movement.

Triceps Pushdowns (Rope or Straight Bar)

A classic isolation exercise, excellent for targeting the lateral and medial heads, and for achieving a strong triceps contraction.

• Starting Position: Stand facing a high cable pulley with a rope or straight bar attachment. Grip the attachment with an overhand grip (straight bar) or neutral grip (rope). Lean slightly forward at the hips, tuck your elbows close to your sides, and ensure your upper arms are perpendicular to the floor.
• Execution:
  1. Extend your elbows, pushing the attachment downwards until your arms are fully extended.
  2. With a rope, you can slightly pronate your wrists and "pull apart" the rope at the bottom for an intensified squeeze.
  3. Slowly return the attachment to the starting position by flexing your elbows, resisting the weight. Keep your upper arms stationary throughout.
• Key Cues: Keep elbows glued to your sides, initiate movement from the triceps, avoid swinging your body, achieve full elbow extension.

Dips (Bench or Parallel Bar)

A highly effective compound exercise that heavily recruits the triceps, chest, and shoulders.

• Starting Position:
  • Bench Dips: Sit on the edge of a sturdy bench, hands gripping the edge beside your hips, fingers pointing forward. Extend your legs out in front of you, either bent (easier) or straight (harder). Slide your hips off the bench.
  • Parallel Bar Dips: Grip parallel bars with a neutral grip, fully extending your arms to lift your body off the ground.
• Execution:
  1. Slowly lower your body by flexing your elbows, keeping them tucked close to your body.
  2. Descend until your upper arms are parallel to the floor or slightly below (for parallel bar dips, your shoulders should go below your elbows).
  3. Push back up to the starting position by extending your elbows, focusing on contracting your triceps.
• Key Cues: Keep chest up, control the descent, minimize forward lean (for more triceps focus), avoid shrugging your shoulders.

Skullcrushers (Lying Triceps Extension)

An isolation exercise that provides a great stretch for the triceps, particularly effective for the long head.

• Starting Position: Lie on a flat bench with your feet flat on the floor. Hold an EZ-bar or dumbbells with an overhand grip, arms fully extended directly over your chest.
• Execution:
  1. Keeping your upper arms stationary and perpendicular to the floor, slowly lower the weight by flexing your elbows. The bar should descend towards your forehead or slightly behind your head.
  2. Feel a strong stretch in your triceps.
  3. Extend your elbows to press the weight back to the starting position, focusing on contracting your triceps.
• Key Cues: Keep upper arms fixed, control the weight, avoid letting your elbows flare excessively, use a spotter if lifting heavy.

Common Mistakes to Avoid

• Using Too Much Weight: This often leads to poor form, reduced range of motion, and reliance on momentum or other muscle groups, diminishing triceps activation and increasing injury risk.
• Incomplete Range of Motion: Short-changing movements limits muscle fiber recruitment and the stretch-mediated hypertrophy response. Always aim for full elbow flexion and extension.
• Elbow Flaring: Letting your elbows spread wide during triceps exercises shifts tension away from the triceps and onto the shoulders, potentially causing discomfort or injury. Keep elbows relatively tucked.
• Ignoring the Long Head: Many triceps exercises primarily target the lateral and medial heads. Neglecting movements that put the long head in a stretched position (like overhead extensions) can lead to imbalanced development.
• Relying Solely on Isolation: While isolation exercises are valuable, compound movements like close-grip bench presses and dips allow for heavier loads and greater overall strength development. A balanced program includes both.

Programming Your Triceps Workout

Integrating triceps training into your routine requires consideration of frequency, volume, and placement.

• Frequency: For most individuals seeking hypertrophy, training triceps 2-3 times per week, with at least 48 hours of rest between sessions for the same muscle group, is effective.
• Sets and Reps:
  • Hypertrophy (Muscle Growth): 3-4 sets of 8-15 repetitions per exercise.
  • Strength: 3-5 sets of 4-8 repetitions per exercise.
  • Endurance: 2-3 sets of 15-20+ repetitions per exercise.
• Placement in Workout:
  • Push Day: Triceps are typically trained after chest and shoulders in a push-pull-legs split.
  • Arm Day: If you have a dedicated arm day, you might start with triceps or alternate with biceps exercises.
  • Full Body: Integrate 1-2 triceps exercises per full-body session.
  • Prioritize compound movements (e.g., close-grip bench, dips) earlier in your workout when energy levels are higher, then move to isolation exercises (e.g., overhead extensions, pushdowns).

When to Consult a Professional

If you experience persistent pain, joint discomfort, or difficulty achieving proper form despite careful attention, consult a qualified personal trainer, physical therapist, or sports medicine physician. They can assess your individual biomechanics, identify any underlying issues, and provide personalized guidance to ensure safe and effective training.
