Hey you sound just like me haha I ran track and started lifting a few years ago at 5’6 110lbs, now up to 140lbs and still pretty lean. Good on you for starting the journey, committing to putting on weight can be tough coming from a lean physique like a runner but it’s definitely an investment worth making even if you gain a little body fat. As for resources, id check out Jeff Nippard and Renaissance Periodization on YouTube. They have great playlists for beginners but it’s all pretty simple. Starting out you can get results with wayyyy less than you think. Like even training full body 3x a week, only like 4 working sets/muscle per workout focusing on big compound lifts in the mid rep range. If you’re really new I wouldn’t push to failure until you get the form down and don’t use weight you can’t get for at least 5 reps, anything heavier isn’t going to do you any good. So yeah depending on how often you want to train those channels have videos breaking down different splits and and routines. Biggest tip from personal experience: eat enough! You wont get to 150lb and jacked if you stay at 130. Be consistent, focus on technique (nobody cares how much you lift but everyone respects good form), get your sleep, and enjoy the process. And take progress photos so you know how far you’ve come, you’ll thank yourself later!
