What's your favorite cardio for someone who hates cardio?

I walk every day but I want more rigorous cardiovascular activity to help my heart with exercise. I would ask this on a different r/ but I need to know what other fat people think. I HATE RUNNING. It hurts my knees, my stomach and boobs jiggle and I get out of breath immediately. It's also -10 degrees where I live and I can't figure out how to dress for running for the life of me. I've taken some yoga classes nearby but they are $25 each and I can't afford it.

What's your favorite cardiovascular activity? Props for it being fat-friendly.

I secretly want to be a runner, ya know, all lean and fit with a high ponytail swinging behind me, effortlessly getting in 5 miles a day. But I get BORED, I get too hot and too cold and out of breath and can't get into it. So if you are a fat person who runs... I'd love to hear from you.

Thanks y'all.
