Yay & welcome! It's great to see some cross over happening and Steem exposure to a lot more who've yet to discover it. One of my closest friends is big in the online fitness area & I'm wanting her to join & bring her huge fanbase here too. I love seeing motivation to be healthy so you've gained a new follower through here in me 😉 Here's a good article on some techy stuff about posting since you're new here. Hope it helps! 😊
