Personal Trainers: Yea or Nay?

So this post is for those of you who have an interest in the health and Fitness subjects. I have a question for you: How do you feel about getting a personal trainer?  Is it worth the money? Those of you that have used one, did you have a good experience or a bad one?  My answer is below. 

There have been two times I have used a Personal trainer twice. Both times it didn’t turn out well. Both times the trainer (who was male) seemed more interested in the females in the gym than helping me.  He would talk to them I’d ask what I should do he would say “go over there and lift this weight ten times”. And then continue talking with the ladies. When I would finish he would say now “go run five laps on the track.” and again keep talking. After the third session. I told him I no longer wanted his services. The second one just talked on his cellphone the whole time. When I canceled with him, he threatened to take me to court because he claimed we had a “verbal agreement for services” and he wanted to still be paid. Needless to say, neither experience left me with a positive impression.

I know this is the exception and not the rule. I am sure there are a lot of dedicated, professional trainers. But how do you avoid getting a hack?  seems like anyone in reasonably good shape can call themselves a “personal trainer” so how do you make sure you are getting a good one? I’d love some feedback from you.
