It is much easier for us to get into shape than it is to stay in shape.
That’s because we don’t necessarily like the path we had to take, whether it was an awful diet or a painful/boring/time consuming workout routine.
Once we see results, we stop.
Pick an effective workout/eating method or program that fits you and that you really enjoy.
If you enjoy the process, chances are you will continue to maintain and exceed your fitness level.
