Routines

Ok you found your BMR and have an idea of what you need to eat in a day. Now what? Well now you can start making up routines! This is my favorite part, since I will ALWAYS have to keep changing it, and try to find new ways to make it exciting! I recommend starting off with a full-body, light-weight workout for anyone that's either starting, or haven't done a workout in more than a year and don't have very physically strenuous jobs.
What I recommend is taking a total of 1-2 minutes per exercise, and repeating it 2 or 3 times, depending on how many exercises you have and how you feel after the first set of exercises. After the first workout, I'd wait at least a day, maybe two before doing the workout again. After a few weeks, your body should starts getting used to that, and I'd recommend starting to specialize the workouts to target more specific parts of the body. For example, have one day be arms, then the next chest and back, then legs. Then same thing again. Once your body starts getting accustomed to that, get even more specific. One day biceps, next day triceps, then chest, then back, etc. Now this sounds like it will only be a month before you're targeting specific areas, but the more specific you get, the longer it takes to get to the next area, so it may take you anywhere from 2-6 months before you're really targeting very specific areas.
Speaking of targeting areas, another thing to remember if you have a fat loss goal is...let me say this clearly, YOU CAN'T SPOT-LOSE FAT! I'm sorry if that came on a little strong, but there are SO MANY people that think they can lose fat only in the belly area, and that's not how it works! So trying to make an abs-only diet and regimen won't be as successful as doing a full-body workout.
A good thing to remember when making a routine is the exercises tend to last about a little over a month before your body starts to memorize the movements and will slow down your progress. This is called the "Plateau". The Plateau is where your progress seems to stop, no matter how intense you make the workout (although sometimes changing the intensity and pace can help spark back some more results and shock the body back into growth/fat loss). To prevent this, you need to change what exercises you do, and how many sets you do, rest periods, how many exercises, and tempo!
