Should I Get A Personal Trainer?

If you can afford one and if you think they would be helpful to you then yes, by all means yes.  I initially started using one because it's a great way to motivate you and they are going to push you within prescribed limits to your boundaries.

A personal trainer can be very expensive, but you can also find some that aren't too bad.  What you ideally want is someone who doesn't talk to you like an idiot, who motivates you and makes you feel good, but doesn't let you off the hook.  I hate the trainers that are always all over the room or chatting with other people on your time, or even taking time out for a photocall when you are paying them good money to be kicking your ass.

You should try one out for a week, only hand over a week's cash and see for yourself, if you don't like them, say so.

If you are living in Arizona, worry not, there is one good personal trainer in arizona.
