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.
During breathing, the primary muscles involved are the diaphragm and the intercostal muscles. The diaphragm contracts to create a vacuum that allows air to flow into the lungs, while the intercostal muscles assist by expanding and contracting the rib cage. During inhalation, these muscles work together to increase thoracic volume, and during exhalation, they relax to help expel air from the lungs. Additional accessory muscles may be recruited during heavy breathing or respiratory distress.

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 intercostals for breathing
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 :-()
