Its good not to tie your self down to one subject what you can do it talk about this subject and then be very specific on what keywords you pick and products you target

Good luck with it all

Kyle does mention this topic several times in trainings. While people may say this is too broad of a niche...I believe, if you make it truly personal/unique and grab those low hanging fruit type keywords in your content, you will make a go of it! The example I think of is me training people for years in martial arts strength training/yoga/ pilates, adapted fitness in general (for people with disabilities.) I used to think ..."what will make people want to come to me?" Say, if I opened my own studio...had a retreat or what have you. I answered myself..."because I am a good teacher, I would want to learn from me, I attract people who want to learn and get better"
My point is that I thought about what others would be attracted to in me. It's the same on the world wide interwebs! Show them your heart and soul. I can see it shining through just in the smile of your profile picture! Blessings, fyre

Hi Aneri Patel. personally I don't think this niche is broad. Fitness can be combined with a lot of other subtopics, like food, exercises etc. So go for it. Make a beautiful website with a lot of tabs-menu and posts.
Good luck
