Beginners typically experience rapid strength gains due to neuromuscular adaptations, as their bodies are not accustomed to resistance training. These adaptations involve improved communication between the brain and muscles, enabling beginners to perform exercises more efficiently. In contrast, experienced lifters often see slower, more gradual gains due to their bodies adapting to the stress of training, necessitating more complex programming (like periodization) to stimulate further progress. Their focus often shifts to muscle hypertrophy and performance improvements rather than sheer strength alone, making continued progression more challenging.
