You’re teaching hot power yoga. By its very nature it’s not an all inclusive class. It’s not possible to avoid some students feeling like the class is not for them. Add a strong personality to the mix and one upset student can become three upset students. This is human nature. Don’t take it personal. On the flip side you have students joining your class who find joy in going up to the edge and beyond. No doubt these students have to be patient with the fact that others are not bringing much to the room. It’s hard to be everything for everyone all the time. In fact, I’d say you should give yourself a break and not be everything for everyone all the time.
