Try different things until you find something that feels good even as an idea. Think about things you like doing and how you like them. For me, I dislike team sports and being surrounded by people in a gym setting. I like doing things on my own, preferably at home while not talking to anyone. I first start thinking about maybe enjoying a spooky story podcast while walking so I start thinking about the temperature and the things I like watching while I'm out, etc. Same for weight lifting, pilates and yoga (Those are my cyclical workouts. I get bored easily) I hype myself up in my head first and then use the "do it for five minutes" method.
I have NEVER said "Well I wish I didn't come to yoga. This class sucked" "That lifting routine was a total waste of time. Not doing it again"
Also, having cute/neat stuff for it helps, just beware of spending habits. Did I need to buy green yoga blocks? No Do they make me Happy everytime I look how they are the exact same shade as my pothos? Yes they do.
