What Happens When We Train? When one trains with weights a stress is placed upon the body. Both the skeletal muscle and nervous systems are stressed by the imposed demand of lifting heavy loads. The nature of this stress and how it affects the body from a physiological perspective is open to discussion and not universally agreed upon by the scientific community. For the purposes of this article we will not delve too excessively into the science of the issue but rather focus on some generally accepted ideas regarding training induced stress and how the body reacts to it. What is Recovery? The skeletal muscle cells incur damage from heavy weight training. The body's response is referred to as recovery. Without recovery the only consequence of training would be harm to the body. Most training systems advocate 1-7 days worth of rest from weight training for a particular muscle or muscle group in order to allow for recovery and hopefully for the adaptation of increased size, strength, or both.
