Understanding how to become a lifeguard begins with being a strong swimmer and completing a certified training course, such as the National Pool Lifeguard Qualification (NPLQ) or the National Beach Lifeguard Qualification (NBLQ). Next, you’ll need to pass a fitness test demonstrating your swimming and rescue skills and obtaining current first aid and CPR certifications. Once qualified, you can apply for lifeguard positions at pools, beaches, or water parks. Staying physically fit and participating in ongoing training will help you thrive in this rewarding role.
