Dumbbell work is the solution if benching causes shoulder pain, you train alone without a reliable spotter, or you find that barbell training does not result in a larger chest.
1. You can do more reps and exercises:
Dumbbells enable you to drop the weights below chest level, extending the pecs to their full extent and activating more muscle fibers.
2. Dumbbells are great for joints:
The human body is just superficially symmetrical. Your shoulders, hips, wrists, and other joints are partially symmetrical.
3. Dumbbells are great for overall strength and growth:
When using dumbbells, you can’t do that since you have to steady and push with equal power from both sides of your body, and you’ll feel any imbalance instantly.
4. Pecs are more effectively trained with dumbbells:
When you bench-press a set of dumbbells, you’ll feel your chest muscles constrict at the peak of the exercise to keep the weights from escaping out to the sides.
