Including strength training in a fitness routine is significant for building and maintaining muscle mass and enhancing overall body strength. Strength training increases metabolic rate, aiding in weight management by burning more calories at rest. It also improves bone density, reducing the risk of osteoporosis. Additionally, this type of training promotes functional fitness, making daily activities easier while boosting overall physical performance. Regular strength training is essential for achieving a well-rounded fitness regimen and supporting long-term health.
