Final answer:
The Pyramiding Training Principle is true; it starts with higher reps and lower weight, gradually increasing the weight to stimulate muscle adaptation and growth.
Step-by-step explanation:
The statement about the Pyramiding Training Principle is indeed true. This training method involves starting a body part session with higher reps and lower weights, and then gradually adding more weight while decreasing the repetitions. This strength training strategy aligns with the necessity of progressively overloading the muscles to stimulate growth and strength gains. The logic behind this is that muscles need to be challenged with heavier loads than they are accustomed to in order to grow. Starting with lighter weights allows for a warm-up and muscle endurance, while the gradual increase in weights pushes the muscles to adapt to higher stress levels, leading to increases in muscle size and strength. This method ensures that the muscles are thoroughly stimulated across a range of intensities for optimal development.
