I'm starting to love cardio

Just started going to the gym a month ago and beside building muscles, I also started to do cardio, specifically the stairs climber. I hate cardio, tried telling myself to do 15 mins each time, twice a week and I'd be dead 5 mins in everytime but still did my best to finish 15 mins. Today I got to 17 mins and felt like I could do longer, I don't feel dead but refreshed instead. Hate to admit that I'm starting to love cardio now but I do, so proud of myself 🥲
