The overhead press is used to improve strength in triceps and shoulders. This exercise works best when done with weights. The author recommends that you do not use a weight that is too heavy for you. If you can't do 10 repetitions of this exercise, you should use a lighter weight. Also, Dr. Berntson suggests that you use one-piece dumbbells, not the kind with removable plates.
Step 1: Sit up straight and place your feet flat on the floor.
Step 2: Grasp a pair of dumbbells and raise them up to your shoulders, palms facing forward.
Step 3: Raise the weights above your head by straightening your arms.
Step 4: Bring the weights together so that they touch each other over your head.
Step 5: Gently lower the weights back down to the level of your shoulders.
Repeat for a total for 10-15 repetitions.
If you have never done this exercise before, your arms may feel fairly wobbly and uncoordinated. This is normal and will go away if you continue doing this exercise for a couple of weeks.
