my story starts similar: I was more than 100lb overweight with blood pressure so high the dentist refused to work on me and a 'resting' HR so high that health watches couldn't even tell when I slept.
I fixed my diet and found some cardio I liked and gradually lost the pounds, was happy to see my HR go lower and lower and into the 50s, and doctors were amazed at how good my blood pressure was.
incredibly, being fat is BAD, and to stop being fat actually directly fixes tons of stuff.
but then my story goes: I got into weird supplements, randomly bought and took stuff after seeing one post or video, which includes a cocktail of 8 different kinds of magnesium with some absorption enhancement.
Then after a month of arc of really shitty sleep and diet, while otherwise feeling completely fine, I noticed that my HR was 47bpm and it finally occurred to me to look up whether was normal or not. "Everything is cancer" websearch says: this is bradycardia, probably heart failure, you're probably going to die.
So I had a very bad time involving a lot more heart supplements that also fucked me up, an ER visit, and a cardiologist who told me to consider throwing my watch away because all I have to do is calm the fuck down. I did not really believe him, but I've gotten the supplement stack down to fresh fruit and natto.
So yeah OP, reducing your HR is easy if you're starting out fat.
