As drunk as a fiddler, I need a trainer to exercise, and it's so expensive that I don't even want to pay for going to the gym, let alone hiring a fitness instructor! For fitness, I search information on the internet and have targeted fitness methods online. Go to the fitness post to see other people's experiences. You don't need a fitness instructor, you have P; The above is my personal opinion. If you have money, you can pay at will.
