What is the deal with Melissa Wood Tepperberg?

Is she legit?

Her recommendations seem to be from companies owned by someone she knows or a product that comes with a discount code. It makes me question whether these things are actually helpful or she is just trying to push her friend’s product or make a check off people using her code.

Also has anyone seen results from her workouts? I am no workout expert by any means but from what I have seen her form does not look great. I wonder what certifications or credentials she has to be an instructor, if any.
