Do you have the ability to adapt your instruction to the level of understanding of the person you are working with?
Can you spot technical discrepancies in a lift? Are you able to provide that feedback, with subsequent instruction, in a positive & encouraging manner?
Are you willing to meet people where they are at in their fitness journey, & then provide a measurable plan for their personal growth (ie-heavier load, no pain in a movement, smoother technique)?
You will be joining an inclusive, encouraging community to further develop your knowledge and experience.
