I can tell you as a Personal Trainer the most annoying thing is for people to think they know more than you, or that what they are doing is better.
Let me give you 1, maybe 2 pieces of solid have-a-personal-trainer advice.
If you ask a personal trainer for advice, don't give them your advice.
2. If you ask for advice and they give you advice, either do it all or shut up.
I can't tell you how many times I have talked to people, given them exercise and nutrition advice, check back with them later or they come to me saying its not working, and I say,"Have you done what I told you?" and they say,"I work out all the time just like you said to." and the nutrition?," Oh well, its too hard to do that, I dont cook, etc take out is easier, can't I just work out more?"
No. Go away. Get out of my face. Go be fat.
Harsh? Maybe. But if there was another way you could do it, i.e. just working out more, dont you think I would have told you?
Idiots.
