It sounds like you’re doing a great job with her, but one of the things that we as trainers have to deal with these days is the whole “biggest loser” mentality. People are getting conditioned to think that losing 7 to 10 lbs per week is not an unrealistic expectation because they see it on TV. There also could be something else going on there, like others have suggested. All you can do is explain to her about what’s realistic & what’s not as far as training goals go. She’s actually losing more weight per week than I would want to see – I’m a big fan of 1 lb per week. But these days, that’s a tough sale. I’d tell her that there’s a right way to accomplish her goals & an unhealthy way, and for her to get another trainer if she insisted on the latter. Good luck Kelly – you might need it with this one!
