I love personal training - don't get me wrong - and the course at AIF was great.
I think CIT is alot better now due to the influx of students and better PT's teaching there.
Some negatives that I've experienced and observed are the 'no shows' and the time wasted because of them (hate), up and down levels of work. if ur an independent PT and want to train someone at a gym, the gym might ask for % or charge you per hour to use the facilities. If u work for a Pt business then they take a cut of your hourly rate.. and if assigned to a gym u may or may not actually train anyone and will find yourself putting the gym rat's weights away. If ur employed by a gym u could be paid the same as the phone bitch or that weird creepy guy who walks around wiping down equipment.
Fortunately my main job is being a public servant and I offer some cardio/circuit work during lunch. I take 6-8 people within my department twice a week 15$ per head, and its enjoyable. Also I train people one on one after work and weekends.
I'm really focusing on the heavylifting and crossfit stuff.. its alot more interesting and I'm starting to train alot more girls who want to lift heavy and get definition as opposed to just being skinny... definitely a positive.
Again these are just my experiences and I do love it. But I've seen alot of people go down this road and not make it because of how hard it can be to secure work.
More than happy to talk to u about more.
