Safety first, safety first, safety first
When I enter a room, I always first have safety, second form and last fun. Going over-the-top fun without the foundation of protection first is a formula for tragedy that I have seen play out in some awful ways. Running all over the place and hopping on the back of treadmills to hype up the class can sound exciting, but it can be incredibly risky to both teacher and client. An example of failing to keep things healthy might even be telling jokes that could be amusing to anyone in the classroom. As a client, in a class or session you can both feel physically and emotionally secure.
Know your lane
You can swerve all over the lane, but don’t leap into another one because you don’t have the skills without training yourself first. For instance, if you are not a licenced nutritionist, remember what nutrition recommendations you are and are not eligible for. Get a trained expert available when the customers ask. To this effect, whether you have questions about food or diet as a customer, ask your teacher their advice on someone they know you should call.
