Yeah. Even two weeks of the free trial plus a one month sub to the app seems worth that Ultimate Beginner program where she talks you through the exercises. One of my offspring, not the now-big rude girl mentioned above, has been doing the first week of it on repeat, workouts 1-3, and it's very good.
Otherwise if you stick with YouTube then Iron seems like a good place to begin. Shortish workouts with decent rest periods. The aforementioned offspring is using 1.5kg-5kg while they learn the ropes.
