I’m a member of my local gym yea and I plan on being a personal trainer or sports performance trainer later on in life and maybe run my own gym.
After I do my GCSE’s I’m going to shoot for as many diploma’s as I can to do with the fitness/weight training industry.
Do It. Realise that to be successful in any business/life endeavour, you have to be able to communicate with random people and strangers freely. You’re gonna have to know how people tick to be successful in running your gym, and one of the best ways of doing that is observing people.
Plus friends are always excellent as company, emotional support and just for fun, not for drinking, partying and crap.
I was like you back at 16 years old. I changed myself completely at age 17, and at age (almost 19 now) I’m intensely active in my university campus, study hard, work hard, and I workout hard, plus I balance out my whole family and friends at the same time. Just work at it. Thats all there is to it.
