After you have made your decision to get fit and healthy, take the time to consider why you have made this decision. It could be for selfconfidence, the oppisite sex, health concerns,or money. What ever the reasons are aslong as they are important to you that is all that matters.  If workouts for building muscle and losing fat are your main objective then you will want to consider weight training, etc.  It does not matter how many reasons there are there could be 1 or there could be 40, as long as they are important to you is all that matters.  Just stay motivated.
