Instead of picking out a canned, pre-planned exercise routine and spending a session watching, counting, and maintaining conversation, a trainer should be trying to visualize what is occurring inside of the body of their client. All people have structural differences (i.e. bones, joints, contractile/non-contractile tissue) that need to be taken into account when designing an exercise regimen; cookie cutter exercises published in magazines or websites serve to perpetuate inaccurate beliefs about our bodies and the personal training industry.
As trainers, we need to re-evaluate our methods and our understanding of the human body. Exercise is invasive to the body. It’s not about what’s occurring superficially; it’s about the forces applied within, like resistance and torque. Keeping in mind the goal of a specific exercise, we must constantly ensure proper joint forces, position, and motion (if any). Things continuously change during the progression of an entire repetition; clients deserve our undivided attention to monitor and, if need be, correct their exercise. We are responsible for minimizing mechanical wear (contact surfaces of joints) by strategically varying activities. This is an awesome role to play—we have the power and knowledge to actually change and alter joint forces!
If you can give clients a one-of-a-kind positive experience with long-lasting benefits, that’s pretty amazing. Chances are they wouldn’t find that just anywhere; if a trainer lacks a certain degree of knowledge, experience, or commitment, they’re coming up short.
