Additionally, hormones are responsible for many adaptations in the muscles. Although such hormones are produced both at rest and during exercise, their concentration is markedly higher during exercise. This phenomenon has been related to the higher physical performance observed in exercise-trained individuals when compared with untrained individuals. Furthermore, strength training typically results in an increase in muscle mass and muscle strength.1
After regular exercise, the muscle mass increases and that leads to increased burning of fat for energy production. Thus, the amount of body fat is controlled and obesity is prevented. For good health and fitness, fat should be broken up just about daily in the muscles. This is also influenced by improvement in the controlling mechanism for body glucose level through regular exercise. Therefore, physical activity has been advised for maintaining body weight and making the muscles firm and toned. Overall, improvements in muscular fitness and health, as well as speed/agility have been observed in those who exercise regularly.2,3
