How To Do An Overhead Dumbbell Triceps Extension


Take a glance around at your fellow gym-goers next time you visit the weights room and it’s almost certain that you’ll see one or two of them doing biceps curls or some other laser-focused biceps exercise. It’s far rarer that you’ll spot someone paying similarly specific attention to their triceps, which is a shame – because if you’re chasing sleeve-bursting upper arms, you need titanic triceps just as much as, if not more than, bulging biceps.

Many exercises such as press-ups or bench presses work the triceps as a secondary muscle, but the triceps extension puts them firmly in the limelight. As a result of this extra focus, you should find that your triceps get stronger in rapid fashion.

You can do the triceps extension standing, sitting or lying down, and either flat or on an incline/decline. You can also do it with different types of weight, like barbells or an EZ-bar, but the advantage of doing it with a dumbbell in each hand is that you will be able to spot and work on any arm strength imbalances. Just be sure you don’t overdo it with the weight, because it’s vital to go through the full range of movement with the exercise to work the triceps correctly and struggling with a dumbbell that’s too heavy will hamper your form.

How To Do The Overhead Dumbbell Triceps Extension

Start standing with your feet shoulder width apart and one dumbbell held in both hands in front of you. Raise the dumbbell above your head until your arms are stretched out straight. Ideally you want to be able to rest the weight evenly in both palms, rather than grabbing the dumbbell handle with one hand over the other. Slowly lower the weight back behind your head, being careful not to flare your elbows out too much. Once your forearms move beyond parallel to the floor bring the weight back up to the starting position. Your upper arms should remain in place throughout the movement.

Aim for four sets of eight to 12 reps.

If you only have one set of dumbbells at home or your gym is limited in its range and most pairs are too heavy, you’ll need to avoid the full move. Holding too-heavy weights above your head is never a good idea. What’s more, this exercise requires you to move your triceps through a full range of motion to work them properly, and going too heavy makes this difficult and increases your risk of a muscle injury.

Instead, take just one of the dumbbells and hold it securely in both hands. This will allow you to perform the reps safely and properly to work the muscles fully because, as with all moves, quality reps count more than quantity.

You can still superset this move with standard or diamond press-ups to work your triceps more thoroughly, as well as strengthening your chest and shoulders. Just remember to focus on moving your triceps through a full range of motion with every rep to ensure you activate more muscle fibres. Because the more fibres that get called into action, the bigger and faster your muscles will grow.
