1. Study with the best. Great instructors remain students at heart and never lose the desire to learn from the best. Develop relationships with mentors and keep up with your continuing education. Do workshops that dive deeper into a particular focus. Take fitness classes outside your niche to open your mind to different cues, stretches, and movement patterns.
2. Work on your voice. Vocal energy has a huge impact on your leadership role when teaching a class (or training one-on-one.) Think of people you greatly admire. Chances are they have great voices. At the very least make sure people can understand and hear you. Consider a local voice class as part of your continuing education or check out YouTube for vocal exercises to increase your range and protect your voice.
