The type of training that focuses on improving muscle strength is known as strength training or resistance training. This involves using weights, resistance bands, or body weight to create a load that muscles must work against, leading to increased strength and muscle mass. Strength training is beneficial for individuals of all ages, but it is particularly important for the elderly, as it promotes muscle preservation, enhances metabolic rate, and improves functional abilities, thereby reducing the risk of falls and injuries. Engaging in a structured strength training program is essential for maintaining a strong and functional body throughout life.
