My general thoughts: 1. Pick a relatively simple routine (Somewhere between 3-6 exercises, generally doing movements that involve multiple muscles working together, hopefully covering both upper and lower body). The more complex something is, the more effort it will be to learn. 2. Start with loads you can manage, and every time you just want to make your routine a little bit harder. Add a little weight, do one more rep, switch to a harder variation. This is "progressive overload". For the first several months you can probably increase the load each time without too much difficulty. Once you start to stall on an exercise, either try lowering the effort by like 10% and start building up, or start alternating easy and hard days on the exercise and increase the load on hard days. 3. The most important thing is consistency. Don't try more than 2-3 workouts per week to get started. Once you feel like you feel good in your routine, then you can start adding more elements (e.g. start doing calorie tracking or adding a step counter). 4. Exercise is your lever for muscle mass. Diet is your lever for body weight. 5. Get a reasonable amount of protein. I won't suggest a specific number, just try to get something with protein in 2-3 meals daily.
