The primary goal of cardiopulmonary resuscitation (CPR) in fitness contexts is to restore effective circulation and breathing in a person experiencing cardiac arrest. CPR involves a set of life-saving techniques, including chest compressions and rescue breaths, which can help maintain blood flow to the brain and vital organs, increasing the chances of survival until medical help arrives. In fitness environments, knowing CPR is essential for trainers and participants alike, as emergencies can occur during physical activity. Being trained in CPR ensures that individuals are prepared to act swiftly and effectively in critical situations to save lives.
