There are some great coaches out there and some not so great which one have you got?
1- No movement/evaluation screen.
Have you been screened for potential injury risks ? most good coaches can do this by just watching clients warm up and then they will modify or issue corrective exercises, @cpfitness we use both warm up analysis and a modified movement screen depending on the program.
2- One size fits all nutrition.
If your eating the same nutrition plan as your coach more than likely your going to fail why ? because its not individualised to suit your needs or lifestyle, there is no one size fits all with nutrition.
3- Is it about him/her or you ?
If your trainer is constantly preaching how many raw eggs he/she eats & what weight they can lift in the gym there probably not too concerned about your progress, most personal trainers get into training because they enjoy going the gym, when in reality coaching people is a different passion.
4- They don't monitor progress.
If your paying for one to one training or a small private group and your trainer just creates the workout on the day leave that gym immediately because your trainer is winging it, and is either to lazy or just clueless or both.
5- Not paying you any attention while you workout.
If your trainer is leaving you to lift or exercise alone while he walks out of the room or even worse stands there scrolling down the news feed or texting, this is not acceptable but remember this PAY PEANUTS GET MONKEYS.
