Tips From Expert

  • Keep elbows tucked Keep your elbows tucked for the duration of the set. This will reduce the involvement of the shoulders, improving the isolation of the triceps.
  • Focus on breathing – Concentrate on breathing, inhaling as you lower the barbell and exhaling as you lift it back up.
  • Create a solid base – Place your feet firmly on the floor and tense your core muscles. This will ensure you lift from a solid base, reducing unwanted movement.
  • Tense your tricep – During the lifting phase of each repetition, concentrate on tensing your tricep muscle. This will improve your mind-muscle connection, and enhance your results.

How to Put in Your Workout Split

The barbell lying triceps extension is an excellent isolation exercise. Unlike other tricep isolation exercises, it utilizes the barbell and flat bench. This allows you to lift more weight from a stable base.

What makes this even better is its versatility, as it can be programmed in a range of workouts and training splits, including:

  • Full Body – Barbell lying triceps extensions fit perfectly at the end of your full-body workout. Because they are such an excellent triceps builder, they can be programmed as your standalone tricep exercise, even with a light weight.
  • Upper/Lower – The barbell lying triceps extensions are a great addition to your upper body workout. Unlike your full-body routine, the upper-body routine has plenty of room to pair it with other tricep exercises. This provides you with some lethal triceps-building combos for serious muscle growth. 
  • Bro Split – The bro split and barbell lying triceps extension are a match made in heaven. A favorite among the bodybuilding community, this triceps exercise slots right in. To improve those gains, pair it with triceps dips. Or better yet, plug it into your complete triceps barbell workout
  • Strength Training – Strength training focuses on the big three lifts; the bench press, deadlift, and squat. However, accessory exercises are used to improve those movements. The barbell lying triceps extension is great for developing your triceps strength, which can improve your bench press and overhead press.
  • Push/Pull – Your push-day workout is an excellent place to program the barbell lying triceps extension. The triceps contribute to all push movements, making this isolation exercise a great addition to your push-day lineup. You can add them at the end of your workout, allowing you to overload them after performing your larger compound lifts. This creates stronger triceps and improves your other push-day exercises.

The barbell lying triceps extension is often programmed toward the end of workouts as an isolation exercise. This leaves more energy for compound lifts at the beginning of the session.

Primary Muscle Groups

Triceps Long Heads

Large muscles located at the back of your arms between your shoulder and elbow. Most outside portion of the tricep.

Effect On Triceps Long Heads

The triceps brachii consist of three heads; the long head, medial head, and lateral head. 

The triceps long head is closest to the body; originating from the scapula and inserting into the elbow. 

During the barbell lying triceps extension, these attachments provide stability and help us keep our arms tucked. As the barbell lowers, these fibers continue to lengthen and contract when we lift.

The barbell lying triceps extension is effective because it takes the long head fibers through a full range of motion.

Unlike tricep pushdowns or dips, which start beside the body, the lying tricep extension begins with the tricep at length. From there it continues to lengthen, going through a greater range of motion which is shown to enhance results.

Secondary Muscle Groups

Triceps Lateral Heads

Muscles located on the back of your arm between your shoulder and elbow.

Triceps Medial Heads

Small muscles located at the back of your arms. Deep to the triceps long heads between the shoulder and elbow.

Effect On Triceps Lateral Heads

The triceps lateral head sits on the outer side of the posterior arm. Considered to be the strongest of the three heads, it originates from the upper arm and inserts at the elbow, extending the elbow when activated.

The lateral fibers contribute to the lowering and lifting phases of the barbell lying triceps extension. This leads to considerable growth of the lateral head fibers, creating a greater width and posterior arm definition.

Effect On Triceps Medial Heads

The triceps medial head is located between the long head and lateral head. Like the lateral fibers, the medial head originates from the upper arm and attaches to the elbow, providing extension at the elbow.

During the barbell lying triceps extension, these fibers engage and perform an eccentric contraction to lower the barbell. Once you have reached the bottom, they contract to straighten the elbow to return to the starting position.

Equipment

Flat Bench Without Rack

Barbell

Barbell

You can use this for a range of arm exercises. Ensure the seat is at the right height. A good alternative would be the incline bench.

Flat Bench Without Rack

This is great for pressing and pulling movements. Ensure the safety catch is firmly locked in. If you can't find this bench, use one with a rack for barbell exercises.

Who Should Do?

Everyday Gym Goers

The barbell lying triceps extension suits almost every gym goer looking to build muscle mass. While lowering a loaded barbell down to your forehead may look daunting, it can easily be modified to suit all levels.

The exercise slots nicely into most workouts. Using a spotter makes it a safe and effective way to create monster triceps. 

Strength Athletes

The barbell lying triceps extension is a brilliant accessory exercise for strength athletes. The role of a strength athlete is to perform the deadlift, squat, and bench press at maximum output. 

By performing smaller compound and isolation exercises, strength athletes can target areas of weakness and increase strength. This results in a more complete biomechanical movement, and greater lifting capacity.      

Bodybuilders

Popularized by bodybuilders, the barbell lying tricep extension remains one of the gym’s best lateral head of triceps exercises. The stable bench and barbell mean you can safely approach your maximum weight.

The firm base of the bench reduces unwanted movement and supports additional weight placed on the barbell. This stability allows lifters to focus on contracting the triceps brachii and performing quality reps, which is ideal for building symmetrical, lean muscle mass.   

Who Should Not Do?

Absolute Beginners

The barbell lying triceps extension should be avoided if it’s your first time at the gym. Yes, the movement is suitable for all levels, however, without a spotter or the advice of a professional, it can lead to injury.

If you decide to perform the exercise, we suggest asking for a staff member’s assistance. They will show you the correct technique, share tips, and spot you for your set. This will ensure your safety during the set.

Individuals With Shoulder Injuries

Avoid performing the barbell lying triceps extension if you suffer from shoulder injuries or pain. The lying tricep extension is safe, however, when the barbell is lowered toward the forehead it can place a great deal of stress on the shoulder.

The shoulder is a shallow joint, requiring additional stability when lifting above the head. If you have dislocated your shoulder in the past, you may lack the stability and control to perform the movement.

During the lowering phase of the barbell lying triceps extension, the shoulder joint is put in a compromising position. If you are working with a shoulder injury, this could result in dropping the weight on your head.

People With Lower Back Injuries

Performing the barbell lying triceps extension may be difficult for those with lower back pain. When the barbell is lowered toward the head, the core must brace and activate to stop your lower back from arching. This can cause pain or discomfort for anyone experiencing pain in the lower back

While the exercise targets the triceps, our shoulders, core, and legs must brace to maintain a firm base. If you suffer from lower back pain and lack core stability, you may aggravate your existing injury.  

Benefits Of The Barbell Lying Triceps Extension

Triceps Development

If you are serious about your triceps training, try the barbell lying triceps extensions. As mentioned, the stable bench gives you a firm base on which to focus your technique. 

The barbell has greater weight capacity, meaning you can increase the weight for big gains. 

These elements make it perfect for your barbell arm workout, and fantastic for increasing muscle growth, improving definition, and enhancing strength. 

Better Pressing Strength

The barbell lying triceps extension is a great way to boost your pressing strength. Our triceps are one of the main muscle groups in all pressing movements including bench press, shoulder press, and dips.

Isolating the triceps with an accessory movement can increase pressing strength. This results in a more balanced and complete compound pressing movement.

Enhanced Physique

The barbell lying triceps extension is excellent for enhancing your physique. The flat bench provides stability that allows you to focus on performing quality repetitions.

Anatomically, the triceps sit below the posterior shoulder. When we increase the triceps mass and improve the definition, the borders become more defined; creating a look of greater separation. This leads to a lean, athletic-looking posterior deltoid and triceps; enhancing our overall posterior physique.

Simple To Adjust And Progress

The barbell lying triceps extension may look complex, but it is easy to adjust and progress once you have perfected your technique.

Beginners can easily start with the barbell and gradually increase resistance using 2.5kg weight plates. This ensures you are safely progressively overloading, which ensures growth. 

Frequently Asked Questions

Are barbell tricep extensions good?

The barbell tricep extension is an excellent exercise for increasing muscle mass. The stable bench and the barbell’s added weight capacity means you can safely progressively overload your triceps.

What is the difference between skull crushers and lying barbell tricep extensions?

Skull crushers and lying barbell tricep extensions are the same exercise. They are called skull crushers because the barbell is lowered toward the forehead. If the bar were to be dropped, it would crush your skull.

How do you target your triceps with a barbell?

You can target the triceps with a barbell by doing seated and lying barbell tricep extensions. While they both target the triceps, lying extensions will improve stability and reduce arching of the lower back.
