Osteoporosis affects 10 million people in the US and is described as the generalized loss of bone density, causing skeletal weakness. When the amount of bone falls below a certain threshold, fractures occur with little or no trauma. There are 206 bones in your body and every one is crucial to staying active and pain-free as you age. Exercise is one of the most beneficial things that you can do for your bones. Choose weight bearing exercises, especially weight lifting, to keep your bones strong and to prevent bone loss. To improve bone density, the key is to keep your feet on the ground such as walking, running or aerobic dance. The impact of your heel hitting the floor sends a vibration through your skeleton that stimulates cell growth in the bones. Exercise prevents bone loss. This is an issue you need to address whether you are 20, 30, 40, 50, 60, or beyond!
