Different fitness levels impact exercise choices by influencing exercise intensity, duration, and type. Beginners may start with low-intensity activities like walking or cycling to build their fitness foundation, while more experienced individuals might engage in high-intensity workouts or specialized training. Additionally, those with higher fitness may actively seek to challenge themselves through interval training or advanced exercise forms. Understanding one’s fitness level helps tailor workouts to avoid injury while promoting progression. Regular assessment ensures that individuals continue to make gains aligned with their fitness goals.
