It took me over three years to be well-enough trained to do more of my daily work on my own - not including my 1-2 hours/week of trainer-led calisthenics/athleticism classes. (If you can give yourself a ballbusting calis class on your own, God bless ya. I know only one person who does, and I admire that person. She's a great ball of energy and good cheer.)
Admittedly, I am a slow learner and was not in great shape when I began this fitness adventure. And I did not know correct deadlift or squat technique. In fact, I did myself some damage in the past out of ignorance.
Why I have needed a trainer, despite the truly burdensome cost:
- To evaluate you and then plan your fitness regimens, advancing as possible
- To train you to do your exercises and lifts properly, to avoid injury and to avoid wasting time
- To instruct about proper nutrition for your fitness goals
- To inspire and push you, through a positive relationship. Even working out with a spouse or buddy can take you to greater heights. Heck, even a pretty gal in the gym can have an effect. Stupid, right?
Eventually you begin to internalize your trainer's voice and direction, as people sometimes do with a therapist. It's like an alter ego. Many of us need that, because many of us do not really know how to push ourselves to the max. Human nature is lazy, mostly, but with plenty of potential.
