Mechanical loading has profound influences on bone remodeling. Disuse or lack of loading causes an acceleration of bone turnover with bone resorption overwhelming bone formation resulting in a rapid loss of bone mass. This type of bone loss is observed in astronauts who spend extended periods of time in the weightless environment of a space station or shuttle. Overuse of bone can cause small cracks or focal damage within the tissue, which in turn stimulates bone remodeling as a reparative process. One of the important roles of bone turnover is to continuously replace and repair damaged bone tissue. Osteoclasts target microcracks within bone tissue preferentially and remove compromised bone tissue. The damaged tissue is then replaced by new bone tissue. If damage accumulates faster than the tissue can be repaired, larger microcracks develop and propagate to form a stress fracture.

*You don’t have to enjoy deadlifting 

*You don’t have to be a cardio-junkie 

*You don’t want to have to squat 1.5 times your bodyweight

*You need not look forward to progressing from push ups- pikes- dips-one arm push ups

You need to train simply because your bones demand it. To remain dense and robust. Stress fractures are not inevitable. Loss of bone density is not a given.

You have some say in how much calcium gets deposited back onto your bones. 

Or you can do it for vanity or pump like most of the training world does and get the strong bones as a bonus.
