@nickale I'm obese (280 > 245) and I had a professional create a routine that works for me. It's a lot of trial and error.
My favourite exercise? On hands and knees, reach out with one arm and the the opposite leg and switch back and forth for as long as I can. I think it's called arm and leg extensions. (L-arm and R-leg up at same time lift up and stretch out, and then back down. Now R-arm and L-leg). I would sometimes do it on my bed cause it was easier on my knees, but I also bought a thick ass exercise pad that did wonders.
I also found just beginner yoga and focusing on stretches was enough for me. When I found a sport I genuinely enjoy (Table Tennis), I was able to get two hours of cardio in like it was nothing. Pokemon go helped for a little while. It all depends on how obese you are and what you're struggling with. The "great shrinking man" started with literally flopping around like a fish, "Just move."
You could offer to walk someone's dog.
Edit: Side note, those are all things I did previously. I'm not really exercising until I get below 240 and have currently lost 25lbs purely on how I eat, with a very slow approach. I've focused on creating lasting and healthy eating habits to replace my bad habits/compulsive binge eating. I used to eat out all the time and now I meal prep and cook at home. CICO I kept bouncing back from weight I loss from exercising cause I didn't address my bad eating habits. This also included replacing my bad coping mechanisms of food with better and ideally wholesome coping mechanisms, like painting. If I gain weight again it will only be another lesson in my toolbox for next attempt, because I only truly fail if I give up.
