Muscle strength refers to the maximal force a muscle or muscle group can generate during a single contraction. It is a fundamental component of physical fitness and is crucial for everyday activities such as lifting objects, walking, and maintaining posture. Muscle strength is influenced by several factors including muscle mass, the number of muscle fibers recruited, the type of muscle fibers present (slow-twitch vs. fast-twitch), and neuromuscular efficiency, which is the ability of the nervous system to activate and coordinate muscle fibers.

Developing muscle strength typically involves resistance training exercises. These exercises involve working muscles against an opposing force, such as weights, resistance bands, or bodyweight. Progressive overload, a principle of training where the stress placed on the muscles is gradually increased over time, is essential for continued strength gains. This can be achieved by increasing the weight lifted, the number of repetitions, or the sets performed. Regular training also leads to adaptations within the muscle, including hypertrophy (an increase in muscle fiber size) and improved motor unit recruitment.

Beyond athletic performance, adequate muscle strength plays a vital role in health and well-being. It contributes to metabolic health by increasing calorie expenditure, helps prevent injuries by supporting joints and improving balance, and can mitigate age-related muscle loss (sarcopenia), which can lead to reduced mobility and independence.
