Now that you have made your decision, try and figure out what is wrong with you. What is it that actually makes you unfit. There may be a chance that there will only be a minute problem with you and you may not be aware of it. It could be anything from unhealthy eating to a less nutritious diet. You only need to analyse. What is staying fit after all? Isn’t it eating healthy? Moreover, each one of us does a few fitness conscious things anyway. Observe those and take inspiration from them. You will see that the journey is a fairly easy one.
