If you're worried about the price of getting started (such as hiring a personal trainer:), think about the cost of staying exactly where you are!
It is baffling that a lot of people wait until they have been diagnosed with a condition and told that they NEED to exercise or else!!! Why wait? Why not start NOW!?
Where you are is not where you have to stay. It is truly up to you.
So MOVE. NOW. Why not?
