Incline Bench Press Alternate Arm
The incline bench press alternate arm targets the upper chest by pressing one arm at a time on an incline bench. Alternating arms challenges core stability and anti-rotation strength while maintaining consistent upper chest and shoulder engagement.
How to do it
- Set an incline bench to 30-45 degrees and lie back holding a dumbbell in each hand at chest height.
- Press one arm upward until fully extended while keeping the other dumbbell at chest level.
- Lower the extended arm back to chest height, then press the opposite arm upward.
- Alternate arms in a controlled manner for the desired number of repetitions.
- Keep your core engaged and avoid rotating your torso throughout the movement.
Form cues
- Keep your feet flat on the floor and core braced.
- Press one dumbbell up while holding the other steady.
- Control the weight as you lower it back to your chest.
- Prevent your torso from rotating as you alternate.
Breathing: Inhale as you lower the dumbbell back to your chest, and exhale firmly as you press the weight upward.
Common mistakes
- Rotating the hips or torso to help push the weight up, which reduces chest engagement and strains the core.
- Rushing the movement instead of maintaining a steady, controlled pace on each arm.
- Flaring the elbows too wide, which places unnecessary stress on the shoulder joints.
Muscles worked
Primary: pectorals. Secondary: triceps, front delts, core.

Why alternate arms instead of pressing both at the same time?
Alternating arms increases the time under tension for each side and challenges your core stability to prevent your torso from twisting.
What should I do if I feel this in my shoulders instead of my chest?
Check your bench angle to ensure it is not set too steep, and focus on keeping your shoulder blades pulled back and down against the bench.
Can I do this exercise with barbells?
This specific movement is designed for dumbbells so you can move each arm independently. A standard barbell bench press keeps both arms locked together.
