When you lift heavy weights, over time your bone density will start to increase, reducing the risk of osteoporosis. Your metabolism becomes more efficient, burning more calories even at rest. Connective tissues, such as tendons and ligaments, strengthen, enhancing joint stability. Hormonal changes will start to take place, with increased production of testosterone and growth hormone. Your nervous system adapts, improving muscle fiber recruitment and coordination. Cardiovascular health improves, with a stronger heart and lower resting heart rate. Body composition shifts towards more lean muscle mass and less fat. Overall, you become stronger, more resilient to injury, and metabolically healthier. #shorts #anatomy #muscle #weightloss
