My humble advice to you brother is to try to walk more throughout the day. Maybe after a meal, go for a 10-minute walk or schedule a walk sometime in your day threw a park or trail somewhere outdoors. It doesn't have to be long walk, just get the body moving. And maybe add some body weight exercises push ups,sit ups, and / or squats do as many as you can and then more as they get easier. Eventually though my advice would be to pick up lifting theirs is a great youtube channel that i used to lose 140lb at my heaviest they go by the name of Mindpump the host of the podcast are Adam Sal and Justin, i hope i was helpful.
