Incline Barbell Bench Press: How To, Muscles Worked & Common Mistakes

The incline barbell bench press is the best exercise for developing the upper chest — the clavicular head of the pectoralis major. While the flat bench press builds overall chest mass, the inclined angle shifts the emphasis upward, targeting the area just below your collarbone that gives the chest its full, three-dimensional look from the front. A well-developed upper chest is what separates a complete chest from one that looks flat at the top regardless of how much you bench press.

If your upper chest is lagging behind your middle and lower chest — which is extremely common — the incline bench press is the exercise that fixes it.

Incline Barbell Bench Press – Muscles Worked

Primary muscles:

• Pectoralis major (clavicular head) — the upper portion of the chest, directly targeted by the inclined pressing angle
• Anterior deltoid — the front of the shoulder assists throughout the press, more heavily than in the flat bench press due to the upward angle
• Triceps brachii — kicks in powerfully to lock out the movement at the top

Secondary muscles:

• Serratus anterior — stabilizes the shoulder blade throughout
• Core — braces to keep your back stable against the bench

How the Incline Angle Changes the Exercise

The angle of the bench is the most important variable in the incline bench press — and the one most people get wrong:

• 15–30 degrees — minimal upper chest emphasis, very similar to flat bench press
• 30–45 degrees — the sweet spot for most people. Significant upper chest activation with manageable shoulder involvement
• 60–75 degrees — shifts the exercise toward a shoulder press, with the anterior deltoid becoming the primary mover rather than the upper chest

45 degrees is the most commonly recommended starting point for upper chest development. If your gym’s incline bench is fixed at 45 degrees, that works perfectly. If it’s adjustable, experiment between 30 and 45 degrees to find the angle where you feel the most upper chest activation.

How to Perform the Incline Barbell Bench Press

1. Set the bench to 30–45 degrees and position it in a squat rack or use a dedicated incline bench with a barbell rack.
2. Lie back against the bench with your feet flat on the floor. Your eyes should be roughly below the barbell.
3. Grip the bar slightly wider than shoulder width — the same grip width you’d use for flat bench press.
4. Retract your shoulder blades — squeeze them together and pull them down into the bench. This is the most important setup cue for protecting your shoulders.
5. Unrack the bar and hold it directly above your upper chest with arms fully extended.
6. Lower the bar slowly toward your upper chest — just below your collarbone. Keep your elbows at roughly 45–75 degrees from your torso, not flared straight out.
7. Lightly touch your upper chest and press the bar back up in a slight arc to the starting position, exhaling as you drive.
8. Repeat for your desired reps.

Incline Barbell Bench Press Pro tip: The bar should touch your upper chest — not your lower chest or your neck. If it’s landing on your lower chest, your bench angle is too low or you’re not pressing in the right arc. If it’s heading toward your neck, your elbows are too far back. Upper chest is the target — visualize the bar traveling toward that spot on every rep.

Incline Barbell Bench Press – Common Mistakes to Avoid

1. Bench angle too steep The most common incline bench press mistake. A bench set above 45 degrees dramatically increases anterior deltoid involvement and reduces upper chest activation — at 60–70 degrees you’re essentially doing a shoulder press. Keep the angle between 30 and 45 degrees for genuine upper chest emphasis.

2. Flaring elbows to 90 degrees Same principle as flat bench press — elbows flared straight out to the sides puts your shoulder joints under significant stress. Keep them at roughly 45–75 degrees from your torso throughout every rep.

3. Bouncing off the chest Lower the bar under control and let it touch your upper chest lightly before pressing back up. Bouncing removes the eccentric stimulus and puts unnecessary stress on your sternum and shoulder joints.

4. Not retracting your shoulder blades This is especially important on the incline because the upward angle naturally pulls your shoulders forward. Actively squeezing your shoulder blades together and down before every set creates a stable base and keeps your shoulder joints in a safe position throughout the press.

5. Letting your lower back arch excessively A slight natural arch is fine and normal. But dramatically arching your lower back and lifting your hips to help press the weight defeats the purpose of the incline angle entirely. Keep your glutes on the bench and your lower back with a natural arch only.

6. Going too heavy too soon The upper chest is typically weaker than the middle chest — most people can lift significantly less on incline than flat bench. Accept this and use appropriate weights rather than loading up to match your flat bench numbers and sacrificing form.

Incline vs. Flat Bench Press

Both exercises are essential for complete chest development — they target different portions of the same muscle:

• Flat bench press — neutral angle, emphasises the middle sternal head of the pectoralis major, allows the heaviest loading. See our Barbell Bench Press page
• Incline bench press — upward angle, emphasises the upper clavicular head, slightly more shoulder involvement, typically 10–20% less weight than flat bench

Most training programs place the incline bench press as the second exercise after flat bench — heavy flat pressing first for overall chest strength, incline pressing second for upper chest development.

Where It Fits in Your Workout

The incline barbell bench press is a compound pressing movement and belongs early in your chest session — either as your primary exercise if upper chest development is a priority, or as your second exercise after flat bench press. Follow it with isolation work like dumbbell flys, cable crossovers, and low cable crossovers to complete your chest training.
