One step at a time.

A man was once asked, " how do you eat an elephant?" His reply was, "Simple! One bite at a time." This should be your belief when it comes to your fitness plan. No matter how impossible your weight training goals may appear, you should understand the fact that you can take small steps towards achieving them.
Ask any person that you see at the gym or running at the park, and they will tell you: No one starts out being in great shape. They will tell you that it is a process. World class athletes and body builders all had to start at the same place you do:at the bottom. The best thing about starting at the bottem is that you have no where to go now but up. So just know that you have to take baby steps until you are able to run in full flight.
So do not get discouraged. If you stick to the program, stay focused, and never give up, you will achieve all of your fitness goals and be on your way to the top!
