“Bone is a dynamic organ, tightly regulated by a multitude of homeostatic controls, including genetic and environmental factors.”1
Wolff’s law = Morphogenesis
“Wolff’s law theorizes that repetitive loading of bone will cause adaptive responses enabling the bone to better cope with these loads.”1
“Smaller loads are unlikely to lead to adaptation of morphology. The highest loads occur primarily in posture and locomotion, simply because of the effect of body weight.” 2
The environmental factor, such as mechanical stimulation regulate bone formation that leads to skeletal adaptation.2 When you apply more loading, strain, and strain above the bone maintenance thresholds, the bone density is greater. The genetic factors cannot be changed, however, the environmental factors such as weight training and cardio exercises can influence bone strength during the growth period.
The spine is mainly loaded by axial compression.3 The best form of training for your spine are mainly upright, continuous and loading exercises as simple as walking, jogging, running, skipping or adding squats and lunges to your weights routine.
Interesting Fact:
A group of women residents in Mae Hong Son Province in Northern Thailand called the Padungor “long-necked” wear brass rings around their neck with an addition of more rings over the years. 4 The weight and force of the rings push the collar bones down and elongates the bones in the neck.

Terminology
Osteoclasts
Break down mineral deposits (old bone tissue) by releasing acid and collagenase enzymes.
Osteoblasts
Build new bone by producing calcium and phosphate mineral deposits to replace the old bone tissues.
