One of the best ways to instruct a participant as a Group Fitness Instructor (GFI) would be to observe the participant’s posture, exercise form, and technique, providing feedback based on those observations. Since all movements are based on an individual’s posture, it’s important to make sure there is proper alignment and good overall posture. What a GFI should look for during a work out:
The head should be in line with the shoulders.
A natural curvature to the spine.
The knees unlocked and soft.
The feet should be shoulder-width apart with weight evenly distributed.
During a routine, it’s crucial to stress the importance of proper form and alignment. A good way to do this is to emphasize keeping the core active and engaged. An instructor in one of my fitness classes always tells the class to “tighten their butt”. The reason for this is that a lot of people have a hard time understanding how to engage their core, yet no trouble tightening their butt cheeks. She said that when you flex your butt muscles, your abs follow suit and automatically engage. I never thought of it in that way, but it works like a charm!
A GFI needs to keep an eye on the participants, and make sure no one is suffering from exercise intolerance or fatigue. Usually the first sign of fatigue is a break down in posture.
