Exercises strengthen bone because they stimulate the work of osteoblasts instead of osteoclasts. True False

True. Regular exercise, particularly weight-bearing and muscle-strengthening exercises, can help increase bone density and reduce the risk of osteoporosis and fractures. This is because when you exercise, you put stress on your bones, which stimulates bone-forming cells known as osteoblasts to produce more bone. This helps to increase bone mass and strength. On the other hand, osteoclasts are cells that break down bone tissue, a process known as bone resorption. While this is a normal part of bone remodeling, excessive bone resorption can lead to bone loss and weakened bones. Therefore, by promoting the work of osteoblasts over osteoclasts, exercise can help to strengthen bones.
