In general everybody is a well-oiled functioning machine with all it needs.
Our bodies are amazing, and will adapt to keep us balanced and upright. We can find this means rolling our feet in, making one leg work as if it is shorter, curving our backs or even sticking our heads forward to make sure we are balanced. These adaptations require parts of our bodies to work differently than they were designed. This is when overuse or misuse of our muscles and joints may start to present as pain.
Like a gymnast running up to the springboard to launch into their routine on the gymnastic horse. If they strike the springboard badly, the routine happens awkwardly and injuries are more likely to occur. If they strike well and balanced, their routine will flow easily and elegantly.
