Yep! This article is pretty good. I especially agree with this:question how qualified the trainers are
I think one can benefit from a generic health club trainer by them giving you some ideas for routines, and making sure you have proper lifting form. A good trainer will provide a full body assessment and help you with some goals and they should create a plan for you to reach them.rule of thumb as a trainer is that if he/she needs to be with me for more than 4 weeks on a professional level, then I'm not doing my job properly.
I think you can do a lot of it yourself - there are so many (too many!) resources online now with routines, videos of form, info about nutrition, etc... LMK if you want me to post anything. I did use a Bally's trainer for awhile and it did help me with my lifting form, but the rest of it I figured out on my own.
