The body responds to different types of strength training by undergoing various physiological adaptations. Resistance training induces muscle hypertrophy, which involves increasing the size of muscle fibers in response to progressive overload. Different training modalities, such as heavy weightlifting, endurance training, and plyometrics, trigger distinct adaptations, including changes in metabolic pathways, joint strength, and muscle endurance. Regularly varying training stimuli can help develop well-rounded fitness and prevent plateaus, thereby enhancing overall physical performance.
