Prior experience plays a critical role in determining fitness levels. Individuals with a background in sports or physical activity often possess better muscle memory, learning efficiency, and understanding of proper form. This familiarity allows them to engage more effectively in new workouts or sports, potentially leading to quicker improvements. Additionally, their past experiences might influence their motivation and mental resilience during challenging workouts. On the other hand, those with little to no prior experience may face more significant barriers to starting their fitness journey but can achieve success through proper guidance and gradual progression.
