One of my biggest struggles is weeding out folks like you trying to sell stuff while presenting as helpful. 🙂
It’s a total time suck.
I struggle with acquiring sports equipment for lessons (https://www.bestadvisor.com/yoga-mat) I also find it troublesome to find appropriate music because of copywriting rights…..
All new music is basically copyrighted. But as long as your gym pays the ASCAP/BMI license fees, you should be good to use any music you like.
