How to Do the Machine Inner Chest Press

Follow these steps to perform the Machine Inner Chest Press with correct form:

1Adjust the seat height and position yourself on the machine with your back flat against the pad.
2Grasp the handles with an overhand grip and position your elbows at a 90-degree angle.
3Push the handles forward until your arms are fully extended, exhaling during the movement.
4Pause for a moment at the end of the movement, then slowly return to the starting position, inhaling as you do so.
5Repeat for the desired number of repetitions.

Muscles & Anatomy

The machine inner chest press uses a pressing motion with the hands moving toward the center of the body, which specifically targets the sternal fibers of the pectoralis major (the inner chest — the portion closest to the sternum). Unlike standard flat press movements, the convergent path of this machine creates horizontal adduction at the end range, where the pec fibers run most horizontally and contract most forcefully. The result is a chest press that combines elbow extension (triceps) with horizontal adduction (pec), and produces a peak contraction where both are maximally active simultaneously.

Pro Tips for Better Results

1Adjust the seat so the handles are at mid-chest height. Too high emphasizes the anterior deltoids; too low reduces the range of horizontal adduction.
2At the end of the press, actively squeeze both arms toward each other — don't just extend the elbows. The medial (inner) squeeze is the defining feature of this exercise versus a standard press.
3Control the return slowly — 3 seconds eccentric. The inner chest is trained as the pec fibers lengthen under tension on the return. Dropping the weight fast wastes this stimulus.

Common Mistakes to Avoid

✗ Not squeezing at full extension

Fix: The 'inner chest' stimulus comes from the horizontal adduction at the end range. Fully pressing out and squeezing both handles toward center is where the target muscle is maximally active.

✗ Shoulders rolling forward as the handles come together

Fix: Maintain scapular retraction — shoulders back and down throughout. Shoulder protraction at the end of the press creates anterior shoulder impingement risk.

✗ Trying to use too much weight

Fix: This machine is a detail and finisher exercise — not a strength machine. Use moderate weight and focus on the peak contraction quality.

✗ Seat position not aligned with the machine's intended path

Fix: Each machine is different — spend time with the seat adjustment before loading weight. A poorly fitted machine position limits range and stresses the wrong structures.

How to Program the Machine Inner Chest Press

Sets & Reps

3–4 sets of 12–15 reps. The inner chest press is a hypertrophy-focused accessory — moderate reps with a peak squeeze on every rep.

Frequency

1–2 times per week on push or chest days.

Where to Place It in Your Workout

Use as the last chest exercise of the session after heavy pressing. It's a detail exercise best done when the pecs are already pre-fatigued.

How to Progress

Increase by 5–10 lbs on the stack when all reps include a 1-second squeeze at full extension and 3-second eccentric.

Variations & Alternatives

Cable Crossover

Two cables set at mid height, crossing over each other at chest level. Provides constant tension (not just peak) throughout the range of motion. Considered more effective for inner chest stimulation than the machine version.

Dumbbell Fly

Performed on a flat bench with dumbbells. Maximally stretches the pecs but loses tension at the top. Complement the machine press with dumbbell flies to cover both the stretch and contraction.

Resistance Band Press

Using resistance bands anchored behind you to press with increasing tension toward the center. Good for home training and mimics the convergent resistance pattern of the machine.
