Most times, we are only concerned about the benefits that come when we exercise our body that we fail to ask questions about what brings about those benefits. The various molecular changes that occur in the body when we exercise are what generate these benefits. There's no doubt exercise is good; it is important for the healthy functioning of the body.
These molecular changes take place in the cells. According to some findings, when we exercise our body, these molecular changes occur very quickly at the protein and gene levels. The effects of these changes strengthen the rate at which some organs function in the body.
For instance, molecular changes that occur in the cells prevent proteins that are found in the cells from damage. Molecular changes also prevent us from developing different kinds of diseases. That is why people are always advised to exercise their bodies to prevent them from type 2 diabetes, cancer, high blood pressure, heart disease, etc.
