Working out is not always the healthiest. What you need are several different routines. This will cause more muscle confusion, which will have a better result. I like using this one website called <sparkpeople.com>. It is completely free, and you can keep track of your nutrition, weight, and it even has some specially-customized workout routines for you.
I hope this information helps. I really like this website, plus it is highly effective. I have started eating a lot healthier now that I am aware of how to have a proper nutrition. It also gives you a huge boost in confidence. Good luck!
P.S. If you are not an adult, then use <sparkteens.com>
