Okay I'd suggest you start out working the exercises they have for you already. Maybe in a booklet or something. You could start doing 3-4 sets of 10 of everything on the setting you feel comfortable with. For fat loss you can do a lot of rowing exercises, I think the Total Gym has that capability, right? So I guess warm up with some rowing and get into your workout from there. Work some muscle groups some days and different ones other days. And it's always important to stretch (before and after, but with a total gym you're pretty much stretched out after, right?) and warm up.
