Anaerobic exercise benefits overall fitness by improving muscle strength, power, and endurance. This type of training, which includes activities like weightlifting and sprinting, enhances muscle mass and boosts metabolic rate. By engaging in anaerobic activities, individuals can increase their tolerance to lactic acid buildup, leading to better performance in both aerobic and anaerobic activities. Furthermore, regular anaerobic training contributes to improved body composition, increased bone density, and greater functional strength for daily tasks, overall enhancing physical health and fitness.
