If however, you are unfit, overweight, lonely, or unsatisfied with the way your life is then it will continue to be this way and get worse unless you do something about it
Movement and fitness needs to be incorporated into your life regularly forever and not just for 12 weeks regardless of how busy you are.
If you achieve a certain level or look within a short time you won’t keep it, you will lose it as quick as you made gains if you stop so incorporating into your life for the long term is what is needed.
The longer you leave committing to make a change, the tougher it will get.
