Miranda and Raindrop, this is why I stopped teaching.
Why do people have to talk so much? As I said earlier, it was only in the day time classes at my old gym. Never in the early AM crowd or after work.
Yes, what Raindrop says is true. You'd better be fit *before* you join. When I first joined the place I am at now, I quickly realized that the classes I go to are not for new exercisers. No one shows any modifications. Heck, I felt like keeling over at first. Everyone in this class (weights, core, boot camp like) looks like me; fit and thin. Anyone else who comes never lasts.
I liked teaching beginners for this reason. They appreciate you. Same when I lead rides.
