My box (CrossFit gym) has a six week "Boot Camp" for beginners. One of our coaches will first do an assessment of a newbie's fitness levels and then advise them where to begin. Our coaches also modify the workouts depending on how long someone has been Crossfitting, if they have any physical limitations, etc.
You make your choices, and you live with them. In the end, you are those choices.
