I'm a fitness instructor and I want to release fitness courses online. Is there a platform where I can upload videos and written content?

Hi Parv, UDemy.com and Lynda.com are really popular platforms to get your courses to the public. I'm not sure how their payment system works though. Hope it helps. Please feel free to revert. Click on the thumbs up or mark it as the best, if you found this useful. Wish You Luck!
