I'm a 16-year-old dude who works out 4-5 times a week. I started lifting around 4 months ago, although I did do some bodyweight exercises for a year before I started lifting. Below are some of my workouts. I'm not too sure whether I'm training optimally or not. I train to failure and have decent form, but I do think I have too much volume. Is it a good idea to cut down on some of the exercises?
almost all exercises include 1 warmup set
