Strength training is significant for bone health because it promotes increased bone density and strength. When muscles exert force against weights, it stimulates the bone-building cells known as osteoblasts. This process can mitigate the effects of osteoporosis and other age-related bone degenerative conditions. Regular strength training, ideally performed at least twice a week, enhances not just bone health but also overall muscle function, stability, and balance, reducing the risk of falls and fractures in older adults.
