I would agree that if you can afford it - go for it!
I have a PT that I see twice a week. He is excellent for many reasons. I never do the same workout twice with him. We are always doing something different, one day it will be boxing, another it will be gym balls, medicine balls, spinning, weights - all sorts! He is very motivating, encouraging me to push myself harder than I do on my own and squeezing that extra rep out of me. He is also an absolute mine of information. Health and fitness are his passion and he admits to being something of a geek about it, always reading and learning about it. So for someone like me who sees exercise as means to an end and something to be endured rather than enjoyed, it's great to have an expert on my side. We get on really well and he's always trying to get me to write a blog about it so he can see the perspective of someone who really has no competitive streak and hates getting sweaty.
I have been learning a lot about my body through exercise, with the help of my PT and it is something I have come to see as an essential part of my journey. I will never be a Gym Bunny but by God I will be thin!
