Final answer:
Adaptations linked to the intensity of a training program include changes in muscle size, strength, and endurance. When performing sets to muscle fatigue but not exhaustion, the muscle adapts by increasing its ability to handle heavier loads.
Step-by-step explanation:
Adaptations linked to the intensity of a training program include changes in muscle size, strength, and endurance. When performing sets to muscle fatigue but not exhaustion, the muscle adapts by increasing its ability to handle heavier loads. This adaptation leads to muscle growth and improved performance. However, extreme intensity without proper rest can cause muscle soreness and other adverse effects.
