Muscular strength is a muscle’s ability to apply force against resistance. In sports, it represents a fundamental physical quality appearing in combination with endurance and flexibility. Working on one’s strength aims at increasing muscular power as well as improving execution speed and precision of movements.
The dictionary defines endurance as follows: ability to resist physical and mental fatigue and suffering. Endurance training aims at increasing one’s cardio-vascular capacity for improved resistance during physical effort.
Flexibility is a physical quality allowing execution of movements with the greatest possible amplitude or joint movement. When associated with stretching and relaxing and aimed at muscular, articular and periarticular systems, flexibility has a predominant role to play in everyday life.
