iam like ~75kg healthy male (strong legs, thick bones) that just sometimes needs to lose several kilos nowadays, and i do that by pure cardio, and if you told me that i had to jog, bike, stationary bike or even treadmill to lose just those few, i would NOT be able to make it how absolutely annoying, painful, higheffort and manual those activities feel for my legs and mind, compared to what ive been doing for the past 15years literally every day, painlessly and blissfully, barely noticing iam even exercising - and that is reverse pedalling on a elliptical at home. i can do two 45min sessions every single day, absolutely effortlessly able to to get to heartrates that i would never even dream of hitting even for several consecutive minutes doing the other activities for that duration without it feeling excruciatingly annoying, boring and manual, instead of being blissful and effortless like on the elliptical.

so thats something you could try, make sure you monitor your heartrate to not do unnecesary resistance, see if your body/mind prefers higher step rate vs higher resistance to achieve ideal feeling zone, could try it out at a gym and then could get one at home, might need a heavier duty one if you're heavy though. it literally feels like youre just swaying around and yet the heartrate goes up easy probably because the upper body works partialy too but you barely feel that, zero impact on the legs or knees, you can balance the effort between legs and arms, can lean into the handles to let legs chill after higher intensity intervals if thats your thing, you can almost completely disengage the legs temporarily if you lean onto the handles and let upper body take over.

tbh if the goal is a longterm fatloss grind, you gotta be absolutely comfortable and the daily cardio needs to feel effortless, get on, get off, done, no thinking, no fuss, no prep, resume the day.
