What were your lifting/workout plans when you were first cleared to do so?

Gentlemen, I posted this in another section but would like to get feedback from you men out there as it will probably be more my speed. I don't mind the women's input but I'm looking for weight lifting advice. I was cleared to start lifting but have to keep it light weight for now. I have experience and have done a ton of research but I'm at a loss for where to begin. I've got a bad back but I'm hoping that building and toning my back muscles will help alleviate it somewhat. I have a lot of videos to follow right now with just body weight workouts and will probably start out with those. I'll keep walking so that will take care of my cardio. What or how did you guys start out. Thanks in advance Gents!!

Thanks @Todd_196 Found a couple of apps that looked good when I did a search for that app. I didn't find "My" Fitness Buddy but did find Fitness Buddy. It asks to create a login right away before anything can be done, is that the one? @BigViffer Really not looking to get huge gains or become "strong as I can". I did that when I was young and really not interested in it at this moment, who know if it will change in time. More just looking to get into descent shape. If the look good comes along with it great. I don't think I'll ever get my "suggested" BMI , I'm just not built that way, but prefer to be a smaller me if at all possible. Thanks again gents!!!
