ISSA can be done from home. Its really simple, just a bit time consuming. It can be done in your part time.
As far as making a career out of being a “personal trainer,” become a salesman. You must be able to talk yourself into getting business. If you cannot convey your abilities, you will not receive many clients.
Also, make sure you have a vast understanding of different exercises and how to make them enjoyable. Most PT clients could care less about powerlifting and you have to understand what they want. They want to sweat, and lose weight. Reguardless if you tell them do not use the scale as a guage to how much progress they are making, they will. There is NO way around that.
If the client cannot see results, many couldn’t care less about how much weight the move, they will be dissapointed. So you have to know and understand what will get the client the best VISUAL results possible. Thats for the MAJORITY of PT clients.
There are the few who want to get stronger, but they are very far and few between. There are also a few that use a PT just as an excuse to go to the gym. When you get these “need motivation,” clients you have to make the workouts fun for them. This includes MAJOR variety.
For the most part PT has nothing to do with training people like athletes. They dont want it. They just want to look good. Thats the way to make money in this business. You must be able to sell yourself like you would not believe. You have to talk yourself up majory as to what changes you can bring to the client. After your rep has hopefuly grown, you can look into starting up your own studio. When you come to that stage, take a few business classes so you get an understanding of how a business runs.
If you want to take further and become like one of the big boys on this board, like CW, years of schooling/reading, and yes degrees are necessary.
