Losses and age
I was just thinking about PE gains and potential losses of these gains if stopping exercising completely. Some say that they have lost nothing while others mention big losses. I have not been investigating these comments but could they be related to age? When you are young the body has more flexibility and better capacity to adjust to temporary changes, e.g. in skin increment. The opposite is true when you are old leading to worse flexibility. This put together would indicate that the potential of losing your PE gains is bigger when you are young as compared to when you get old.
Am I right in this assumption?
