The primary aim of a regimen focused on muscular fitness is to develop both strength and endurance in the muscles. This encompasses enhancing the ability of muscles to exert force (strength) and their capacity to sustain activity over time (endurance). Strength training helps build muscle mass, increases metabolism, and can prevent injury by strengthening the muscles around joints. Endurance training complements this by improving the muscles' ability to sustain repeated contractions over extended periods, which is crucial for performance in various physical activities.

In contrast, options such as improving only cardiovascular health and solely focusing on flexibility do not encompass the broad objectives of muscular fitness. While cardiovascular health is important for overall fitness, it is a separate aspect from muscular fitness. Similarly, flexibility is crucial for overall body function and can aid in injury prevention, yet it does not directly address the development of muscle strength and endurance. Lastly, the goal of increasing body fat percentage contradicts the purpose of fitness regimens, as most fitness goals aim to reduce or manage body fat for better health and performance.
