I'm an independent contractor at a local gym (as a cycling instructor). I teach both freestyle classes as well as those from the company Les Mills. I purchase my own music in addition to the pre-coreographed playlists from Les Mills, and I'm thinking about Cyclocore for cycling tips that I can use in my classes. In addition, since cycling is a niche sport I buy expensive cycling outfits that can only be used for such. Basically, what I'm asking is - can any of this be written off as a deduction on my taxes?
