Bench presses - both dumbbell and barbell - work the chest muscles but not always to the extent you would think.
Especially if your shoulders and triceps have a tendency to overpower the chest muscles.
This is where an exercise like a squeeze press would be a great addition to your workouts.
The chest muscles are worked when adduction takes place (the arm moves closer to the mid-line of the body).
By squeezing two dumbbells together it puts the chest in constant adduction throughout the exercise.
If you want a quick demo of how this would feel - place your hands together in front of you and squeeze them hard. You should feel your chest muscles kicking in.
