make a schedule/routine so you can stick to it. that’s the hardest part of the process. so try to use an app or something to come up with a workout structure and track progress. i used fitbod when i first started, but there are other options as well. just don’t pay for any of them the free versions were enough
try out new exercises/workouts and find what you enjoy! and don't feel bad about missing a couple days at the gym (or even a couple weeks) because you won't really lose progress and you can always get back into the swing of things. also it's better to take at least one rest day a week than going to the gym every single day (speaking from experience lol)
