My sister is overweight, she is pretty shy about telling me the actual number, but I'd say she is around 280-300lbs. She'll eventually tell me, but since this is day 1 I'm not going to force it out of her. Anyways, she has asked me to help her get into shape. The diet portion I find pretty easy since good foods are good foods, but i'm having a hard time with the workout portion. We did a back workout yesterday, but I wasnt sure where to start her off weight wise and how many rep/sets. I personally do a high volume routine, but I don't think that is optimal for a beginner. I was thinking of a TBT 3 times a week, but I don't know if teaching her how to squat or deadlift off the back is a good idea.
So to sum things up, can anyone offer advice on a beginner female routine and how do I decide what weights are good for her to start out with?
