"Make sure your trainer has some kind of degree in the fitness field or a certificate from a nationally recognized organization.However, just because someone has a piece of paper doesn't necessarily mean they are a good trainer. Make sure that along with their degree or certification, there as been some kind of practical "hands on" training in the gym.
Ask yourself these questions... Was there any fitness testing preformed? Were you asked to fill out any kind of profile sheet? If not, were you asked about your lifestyle and eating habits?
If your trainer hasn???t done any of these things, I would suggest looking for another.. " (John Platero)
Scotty's right I would use one until you feel comfortable on your own and ask around too... The cost around here ranges from $25-75 per session.. Of course this depends on the duration of the session too...
