Thank you so much for writing this reply!
Since this community is mainly aimed at dance and music lovers, I suggest that you create your own community.
In the beginning, it's not going to be easy but in the long term it's going to make you proud of having created a useful community.
Lately, I created this community aimed at musicians who create original music. There are only a few posts but I'm already happy with it. This is the community, https://steemit.com/trending/hive-172126.
Of course, you can create fitness posts in this community and tomorrow @danceandmusic will announce "Keep fit and have fun week 61". This is the latest link, https://steemit.com/hive-118409/@danceandmusic/keep-fit-and-have-fun-week-60-see-who-took-part-in-keep-fit-and-have-fun-week-59.
