How to do the dumbbell triceps extension
The dumbbell triceps extension trains your triceps. Here is how to do it with good form.

Step by step
- Grab a dumbbell and stand tall.
- Lift the weight overhead and place your hands flat against the top weight plate with your palms facing the ceiling.
- Bring your shoulders back and engage your abs.
- Take a breath and lower the dumbbell behind your head while keeping your elbows to the sides of your head.
- Bend your arms until you feel a stretch, and extend your elbows as you breathe out.
