my 2 decades of experience with personal trainers
They are mostly:
* greedy with money, want renewal with their contract with you way before end of it and if you dont pay further, they will act naughty such as refusing to meet you or give you black face or give lousy job. in a recent case, the trainer threatened me to buy another US$5000 worth of 'sessions' even if i had US$6000 worth of sessions unused, if i dont give in, he (or they) will play games to sabotage my training (eg, book you in and attend another client, being late, send you on the treadmill and ignore you, change people to attend you so nobody follows up your situation properly, high pressure sales)
* have no empathy or ethics in your financial well being
* think too highly of themselves and arrogant
* unable to write their own technical terms out, think they are knowledgable and skills but unable to pass a written test themselves
* fake friendship, share no genuine interest in others for the long term. only have interest in taking large sums of money for little effort or time spent
* teach very limited amounts of true skills and knowledge so you will never become independent
* a big thick book of lies and deceit - tell you they will go on sail go to bbq go to clubbing with you etc to get money from you, and nothing really materialise. they are professionals in dating games with no integrity.
