Comments and tips

  • When you have finished, bring the dumbbell around your back and rest the lower end on your shoulder. Grab the bar securely with both hands, one on top of the other, raise your knee, and gently bring the other end of the dumbbell down onto your knee.
  • When performing the seated dumbbell overhead triceps extension, keep your elbows close to your head. This will keep the emphasis on your triceps brachii. If you have to open up your elbows (move them away from your head) to raise the dumbbell, it means that the dumbbell is too heavy.
  • Your upper arms must be kept vertical. If your shoulder flexibility does not permit this, sit with your hips forward and rest your back on a chair.
  • Try not to raise the dumbbell directly over your head, as this can be dangerous. Tilt your head forward a little, and raise and lower the dumbbell behind your back.
  • The point of sitting down is to reduce your ability to cheat by using body momentum to raise the dumbbell.
  • See also the overhead barbell triceps extension, the seated two-arm overhead dumbbell triceps extension, and the seated Olympic triceps bar overhead triceps extension.
  • You can also try this in a standing position, as in the standing dumbbell overhead triceps extension.
