What is "maximum strength" focused on?

Maximum strength refers to the greatest amount of force that a muscle or group of muscles can generate in a single effort. This concept is primarily focused on lifting heavy weights, which is why the correct answer emphasizes high weight lifting. Training for maximum strength typically involves performing exercises with loads that are close to an individual’s one-repetition maximum (1RM), usually within the range of 85% to 100% of their maximum capacity. This type of training helps to increase muscle fiber recruitment and improves neuromuscular efficiency.

Other options like routines with low weights focus more on muscular endurance or cardiovascular training, which do not aim to maximize force output in the same way. Thus, maximum strength training distinctly targets the ability to lift heavy weights, leading to increased strength levels.
