Before exercise can affect bone density, it needs to be high impact and weight bearing.
Activities such as running, weightlifting and high intensity interval training can have a profound effect on bone formation this brings about an increase in the load on your bones, which eventually forces them to adapt so as to tolerate the strain that comes with those activities.
Whenever you lift a weight, jump and land over and over again, a compressive force is created which causes fluid to flow within your bones tissue.
The degree of flow is relative to the strain imposed by the exercise.
The greater the strain, the greater the exercise’s potential impact on bone transformation.
