Overhead tricep extension

When performing the exercise, it's important to keep your elbows close to your head and avoid letting them flare out to the sides. Keep your core tight and your back straight, and avoid arching your back or leaning forward. You can adjust the weight of the dumbbell to make the exercise more or less challenging, and you can also perform the exercise one arm at a time if desired.

Sit on a bench with a backrest, or do it standing and hold a dumbbell in both hands with an overhand grip.

1. Raise the dumbbell overhead, extending your arms fully with your palms facing each other.

2. Lower the dumbbell behind your head, bending your elbows so that they are pointing upwards.

3.  Extend your arms and lift the dumbbell back up to the starting position, straightening your elbows.

Repeat the exercise for the desired number of repetitions.
