Hey, you just started yesterday. Take it easy, the followers will come. Engage in discussions, like and comment other people's workouts and photos and you'll make friends. Having followers is nice for sure, but it's not an end in itself.

I need chicken!

I hope Scotty ate! LOL

I'm going to be straightforward with you. Soliciting for followers won't get you more followers. People won't think "hey, here's an interesting and nice person I want to follow". They're more likely going to get annoyed. Engage in interaction with other people, and they'll naturally engage in interaction with you. Spend some of your time on other people, and they'll spend some of their time on you. It's a give and receive game where you gain mutual respect for each other.
