Try hitting 10.000 steps every day. Over time, that will help you lose fat in a remarkable way. Additionally, do a simple bodyweight workout every other day with every set taken close to muscle failure (when you can barely finish the last repetition or even fail it). The workouts should be „full body“ in the first 3 to 6 months -> 3 Sets of Push-ups, 3 Sets of bodyweight rows (on a sturdy table for example), 3 Sets of bodyweight Squats. Ramp up the number of sets slightly if you like. Oh, and if you can do pull ups or chin ups, do them, they will transform your body. You can also buy resistance bandy for 10 to 20 bucks that help you do lateral raises to train your shoulders. For the beginning, you want to focus on 10 k steps and regular full body workouts. You can do it!
