One way of tapping into your own natural resources is to purposely subject the body to reduced oxygen intake for a short period of time. When the human body is exposed to situations in which there are reduced oxygen levels – such as high altitude, or by holding the breath – adaptations take place that force the body to increase oxygenation of the blood. Even if you are not a competitive athlete, using these techniques will allow you to get the most out of your workout and accelerate whatever fitness programme you undertake. Who doesn’t want to do more with less effort?
