O is for Osteoblasts and Osteoclasts. These are the two types of cells responsible for keeping our bones in balance. The blasts build the bone, and the clasts consume the bone. Too many osteoblasts and you’ll keep growing, too few and the osteoclasts will eat up all your bone!!!!!!
When these are in balance over the course of a year, about 5%-10% of your bone is replaced.
When we break a bone, our bodies increase the bone-building process due to the trauma of the break. We can mimic this trauma daily in a very subtle way by doing activities that cause impacts. So, for example skipping for 5 minutes a day would activate the bone rebuilding process.
