Alternating DB Incline Bench (How To, Benefits & Modifications)

The Alternating Dumbbell Incline Bench Press is a compound exercise that targets the chest while engaging the shoulders and triceps. Performing the movement with one arm at a time challenges your stability, activating the core and stabilizer muscles. This variation is great for building unilateral strength and correcting imbalances.

Primary Muscles Worked: Pectoralis Major (Upper Chest)
Secondary Muscles Worked: Anterior Deltoids, Triceps Brachii
Equipment Needed: Dumbbells, Incline Bench

Step-by-Step Instructions

1. Set-Up:
   • Adjust the bench to an incline (30–45 degrees).
   • Sit on the bench with a dumbbell in each hand, resting them on your thighs.
   • Lean back and press both dumbbells up so they are directly above your shoulders with your palms facing forward.
2. Execution:
   • Lower one dumbbell in a controlled manner until your elbow forms a 90-degree angle or the dumbbell is in line with your chest.
   • Press the dumbbell back up to the starting position.
   • Repeat the movement with the opposite arm while keeping the other arm locked out at the top.
   • Continue alternating arms for the desired number of reps.
3. Tips for Proper Form:
   • Keep your shoulder blades retracted (pulled back) to protect your shoulders.
   • Avoid letting your lower back arch excessively—engage your core throughout.
   • Use a full range of motion to maximize muscle activation.

Key Benefits

• Targets the upper chest more effectively than a flat bench press.
• Improves unilateral strength and balances out muscle imbalances.
• Engages the core and stabilizer muscles due to the alternating movement.

Modifications and Variations

• Easier Option: Use lighter dumbbells or perform the movement with both arms pressing simultaneously.
• Harder Option: Use heavier dumbbells or pause at the bottom of each rep for added time under tension.

Common Mistakes

• Rushing the Movement: Perform the exercise with control to avoid losing stability.
• Uneven Pressing: Ensure the non-moving arm stays locked out while the other arm is working.
• Flared Elbows: Keep your elbows slightly tucked (at about a 45-degree angle) to protect your shoulder joints.
