intercostal muscles
During exercise, the body requires more oxygen to fuel the muscles, which leads to an increase in breathing rate (respiratory rate) and heart rate to deliver more oxygenated blood to the muscles. This helps to meet the increased energy demands of the body during physical activity. Regular exercise can improve cardiovascular and respiratory system efficiency, resulting in lower resting heart rate and more controlled breathing.
These would be the abdominal muscles.

The diaphragm and intercostals for breathing
The intercostal muscles are located between the ribs and help expand and contract the chest cavity during breathing. When you inhale, these muscles contract, lifting the ribcage and expanding the chest cavity, allowing air to enter the lungs. When you exhale, the intercostal muscles relax, allowing the ribcage to lower and the chest cavity to decrease in size, pushing air out of the lungs.
The diaphragm and external intercostal muscles are primarily involved in changing the thoracic volume during breathing. The diaphragm contracts during inhalation to increase thoracic volume, while the external intercostal muscles help lift and expand the rib cage.
Well your heart is used for breathing it's a cardiac muscle by the way :-()
Your resting cardiac out put is about five liters per minute. During the exercise the cardiac out put increases from five liters to more than twenty five liters per minute. Muscles get about twenty liters of blood per minute. The heart has to beat faster to provide this extra blood. Faster breathing provide the extra oxygen, that is needed for the metabolism of the muscles.
