EXCERCISE INTENSITY -Simply put it can be categorised into three parts 1- Mild physical activity 2- moderate physical 3- Vigorous physical activity. According to Wikipedia– Exercise intensity refers to how much energy is expended when exercising. Perceived intensity varies with each person. It has been found that intensity has an effect on what fuel the body uses and what kind of adaptations the body makes after exercise. Intensity is the amount of physical power (expressed as a percentage of the maximal oxygen consumption) that the body uses when performing an activity. For example, exercise intensity defines how hard the body has to work to walk a mile in 20 minutes

According to MAYO CLI NIC -When exercising, one is working hard or hardly working? Exercising at the correct intensity can help you , get the most out of the physical activity .Even small amounts of physical activitivities are helpful, and accumulated activity throughout the day, adds up to provide health benefits.

One can also do a combination of moderate and vigorous activity. 2- Strength training. Do strength training for all major muscle groups at least twice a week.

It is due to a phenomenon of the brain known as neuroplasticity-That is regenerttion of neurons. Neuroplasticity also increases due to production of BDNFBrain derived neurofactor,which is increased during execise. Besides, it improves mood, better for sleep and sex life.
