Start slow, don't push until your broken, just push enough so your body has to adapt. If you've not been doing a lot of exercise just starting walking for 30 mins 4 times a week can be a good start. After a couple of weeks you'll start adapting to that and feeling a lot better. Then you might want to join up at a gym. I'd say start with something easy like the machines for a few months. The machines aren't the best way to lift but they're pretty hard to get wrong, come with instructions and get you used to going to the gym. Limit your time at the gym. For me 40 mins and I'm out. If you feel like you have to be there for a long time it can impact the rest of your life and cause you to give up on it. Regular workouts are key to changing. Not one off insanely intense marathon sessions. After 3 months or so you'll start noticing a little more energy and confidence. I'd say it's time to learn some barbell lifts. Deadlift, squat, bench press and overhead press. Get good at those over a year or so and you'll be amazed at the changes you see. Starting strength is a great book to get you going on those lifts. If you can afford it a trainer is also a great way to start. https://athleanx.com/ https://athleanx.com/ is also something I've heard nothing but good things about. Mobility is also huge, learn to stretch from day one. You'll feel amazing if you can get in 20 mins 3 times a week.
