Dumbbell Bench Press

Muscles Dumbbell Bench Press Works

Muscles used

• Pecslarge chest muscles covering the front of the chest
• Tricepsback of the upper arms
• Front deltsfront of the shoulders
• Serratus anteriorsaw-shaped muscle along the side of the ribs under the armpit
• Rectus abdoministhe front abs, commonly called the six-pack

Main musclePress the dumbbells up from the sides of your chest as your elbows extend. The main muscle driving this movement is your pecs. Your pecs bring your upper arms toward the centerline and press the dumbbells over your chest.

Supporting musclesYour triceps help straighten your elbows, your front delts assist the press, and your serratus helps keep your shoulder blades stable so the dumbbells do not wobble.

How it should feelAs you lower the dumbbells, your chest should stretch open. As you press up, your chest should squeeze inward and feel firm.

Signs you're offIf the dumbbells drift outward or only your front shoulders feel loaded, you are likely stabilizing with your shoulders and arms more than pressing with your chest. If your lower back arches hard, your trunk is losing position.

Remember thisPress the dumbbells up and slightly in over your chest while keeping them steady.
