Why Are Chest Muscles So Important?

The chest muscles, also known as the pectoral muscles, include the pectoralis major, pectoralis minor, and the muscles that form the walls of the thorax such as the intercostal muscles.¹

The chest muscles are crucial for supporting respiration, upper body movements, and maintaining posture. Respiration is a critical physiological process necessary for delivering oxygen to tissues and removing carbon dioxide from the body. The primary muscle of inspiration is the diaphragm, which, when contracting, increases thoracic volume and decreases intrathoracic pressure, allowing air to flow into the lungs.^{1, 2, 3}

There are different variations of exercises to strengthen the chest muscles, including free weight exercises such as the dumbbell press and variations of pressing movements like flat, incline, and decline bench presses.³

To implement exercises for health benefits, start by:

1) Incorporating resistance training for the chest muscles into your workout routine, which can include exercises such as push-ups, bench presses, and dumbbell flyes.

2) Engaging in activities that require the use of your chest muscles, such as swimming, rowing, or rock climbing, naturally strengthens these muscles through functional movement.

3) Practising proper breathing techniques to ensure the respiratory muscles, including the diaphragm and intercostal muscles, are functioning optimally and improving overall respiratory health.

4) Paying attention to posture, both during exercise and in daily life, to maintain alignment and reduce strain on the respiratory muscles.
