Personal Trainer

I would just like someone who can help me get into shape that has a large knowledge base on physical fitness. I am pretty out of shape and need a lot of work, and I need someone who will help push me to keep me going, but will at the same time know whether or not they're pushing too far physically. I'm there mentally, but physically, I'm years behind. I also need someone that can be available to me between 2:30pm and 5:30pm. I would prefer a female, only because I am married and my husband may not appreciate me spending time with another man while he's a work.
