Quite right. Incorrect exercise, too intense training or incorrectly selected weight in strength training can be very harmful to your health. In order to achieve your fitness goals in the fastest and most efficient way, you need to consult a personal trainer (or a qualified physical therapist if you are going through an injury recovery period) to get a personalized training plan that is appropriate for your age, fitness and health condition. If you want to learn more about the theory and methods of sports training or to get a personal trainer certification, then you should read this post https://traineracademy.org/training/nasm-study-guide/ . Here, the process of preparing for the NASM personal training practice exam is described in great detail and clearly, there are links to the necessary study materials and a fairly well-structured step-by-step plan for repeating and / or studying the curriculum of the course.
