The Subtle But Essential Role Of The Triceps Brachii In The Deadlift

Obviously, the triceps is not what I consider to be a prime mover for the deadlift, unlike the hamstrings, glutes, lats, and erector spinae. However, maximally contracting your triceps prior to pulling the weight off the floor will improve your deadlift in the following ways:

  1. Decrease the chance of a biceps brachii tear
  2. Lengthen your upper extremity to the max, helping decrease the distance (albeit small) the bar travels from the floor to lockout
  3. Help lock down your lats prior to the start of the lift
  4. Increase your grip and contribute to the overall tension in the body and the “wedge” prior to liftoff through the principle of irradiation
  5. Look really cool in photographs of your deadlift


By maximally contracting the triceps, you also maximally lengthen the biceps prior to the start of the deadlift. Why is this important? A lot of lifters, whether in the gym or at a competition, leave a little slack in their arms, consciously or not, before they start the lift. This creates an automatic lengthening followed very quickly by a rapid straightening of the elbow, all under an extreme load while the weight is coming up.

Over time, this will create cumulative micro-trauma in the bicep, especially at the insertion on the forearm. This can lead to a weakening of the biceps and persisting pain, especially near the elbow joint. At some point, if left uncorrected, the lifter will suffer a partial or complete tear of the muscle, forcing him or her to take time away from the barbell to recover.

As we teach at the SFL Barbell Certification, starting the pull with a maximally contracted triceps, takes all the slack out of the upper extremity, preventing the micro-trauma from occurring at the start. This in turn will allow the biceps to adapt to the lengthened position under load, making it more resilient over time.


I love physics and math. Everything we do at StrongFirst is influenced by these two disciplines, and the deadlift is a great example. Let’s take a look at the calculation for work: Work = Force x Distance

In our scenario:

  • Work is the amount of energy expended to move the loaded barbell a certain distance
  • Force is the weight involved
  • Distance the length of travel of the barbell

By maximally contracting your triceps, and achieving full extension of the elbow (0o degrees) before the barbell starts to move vertically, you actually decrease the distance the bar travels. This contraction of the triceps is similar to “pulling your kneecaps up” during the kettlebell swing, in which you are contracting your quads and achieving full extension of the knee. You also create a better wedge at the beginning in addition to preventing curling of the bar during the lockout phase by maintaining the contraction of the triceps.

Note: “Curling” refers to lifters’ bending their elbows to “assist” the lockout. Most of the time this is also associated with some sort of shrugging of the shoulders to “aid” in the completion at the top.

I tell the students at the SFL Barbell Certification that I want to see all three heads of the triceps as they set up for the deadlift. Seeing all three heads present ensures a proper lengthening of the upper extremity and decreases the stress to the bicep. Plus, the slack is taken out of the arms, helping ready the body for the lift.

Triceps Brachii in the Deadlift

All three heads of the triceps should be visible in the deadlift.

Again, by lengthening your arms (contracting your triceps) at the beginning of the movement, thedistance the bar travels from start to finish will decrease, thereby lowering the amount of work you need to do to lift heavy weight.


If you have attended an SFL, you undoubtedly heard me say, “Use your….” which by the end of the cert weekend, everyone finishes for me by shouting out the word, “Lats!” In the deadlift, we use the lats to help lock down the torso and contribute to its stiffness during the lift, helping make the deadlift a true hip hinge versus a many-body-parts-hinge that we see a lot of.

What does this have to do with this article? The triceps is made of three heads, hence the name. It has a long head, lateral head, and a medial head. When perusing an anatomy book, you will see the long head attaches to the scapula below the glenoid cavity. Just like the lats, it helps to extend and adduct the humerus. When you are setting the lats for the deadlift, contract your triceps hard and you will feel a further increase in the ability of your lats to “squeeze” and tighten.

Now, holding that position, and with your arms hanging straight down by your sides, watch what happens when you contract your triceps hard. I’ll wait… Did you feel that? Now do that right before you pull off the floor and not only will it help lock down your lats, it will also help keep your arms straight at lockout and help you finish at the top.


In addition to helping lock down your lats before the lift starts, maximally contracting your triceps will raise the tension-o-meter needle in your body. Remember, the more tension you can develop before lifting heavy weight, the greater the chance you will be successful during your set and the lesser the chance you’ll be injured.

Crush the bar with your grip, maximally contract your triceps to lengthen your arms and help lock the lats down, anti-shrug as hard as you can (LATS!), and squeeze your abs—and guess what? You just generated more power and strength by creating a “wedge” to deadlift from.

Interesting to note is that most lifters don’t use the triceps properly when deadlifting. Go watch someone deadlift at the nearest gym. They may be crushing the bar, even using their lats and abs, but their triceps will be soft, creating a crack in the tension system while at the same time leaking energy and potentially setting themselves up for injury in the future. I see this all the time when I am refereeing powerlifting meets.


Enough said! It’s awesome to see someone deadlifting heavy weight and see the three heads of the triceps working hard. You know at this point the athlete is generating a tremendous amount of tension and is serious about moving some weight.

Next time you are deadlifting, squeeze those triceps as hard as you can before the weight leaves the floor. Show all three heads of the triceps throughout the lift. You will generate more strength and power and reduce the incidence of injury to your biceps tremendously. Enjoy the increase in your deadlift!
