Which training method focuses on increasing strength through progressively heavier weights?

1. High-intensity interval training (HIIT)

2. Progressive overload

3. Bodyweight training

4. Concentration training

The correct answer is: Progressive overload

The training method that focuses on increasing strength through progressively heavier weights is progressive overload. This principle is fundamental in strength training, as it involves gradually increasing the amount of weight used in exercises over time. The aim is to challenge the muscles beyond their current capabilities, leading to adaptation and growth in muscle strength and size. Progressive overload can be achieved not only by adding weight but also by varying other factors such as the number of repetitions, sets, or rest intervals. However, the hallmark of this approach is the systematic increase in resistance, leading to continuous improvement in strength. This method is essential for athletes and individuals looking to improve their performance and achieve their fitness goals effectively. The other options, while they involve different aspects of training, do not specifically focus on the systematic increase of weight to stimulate strength gains. For example, high-intensity interval training (HIIT) is more about alternating periods of intense effort with rest, bodyweight training emphasizes exercises that utilize the individual's own weight, and concentration training typically refers to mental focus rather than a specific strength training methodology.
