Personal Trainers have been part of the problem not part of the solution (apologies).
Today personal trainers need to not be trainers at all, they should re-model themselves into lifestyle educators. Personal Trainers want work for money and must compete for clients. Thus a personal trainer needs to be different, to educate about supplements (which are 99% marketing) to espouse about mental health, happiness, relaxation and less stress.
Make yourself into the GoTo Guru from anything such as CoEnzyme CoQ10 to natural hormonal replacement therapy. This way you will make money hopefully following your passion and hobby. You show people how to solve their own problems, if you give people their lifestyles back you will have more recommendations than you will ever be able to fulfill ! ! !
Yes a GoTo Guru!! The industry is flooded with personal trainers who are only about making money and they dismiss the other aspects of health and the dangers of chemically processed supplementation. Not to mention they can cause serious injury physically!! Majority of physical health are a direct result of poor mental/emotional health and needs to be supported.
