Lol I was about to say everyone would just recommend stuff based on *their* preferences, and this thread proved me 100% right.
If your goal is mainly muscular hypertrophy (making your muscles bigger), you want to do sets of 8-12 reps primarily. You can and should find a free hypertrophy-based program for beginners online, but if you're too proud to do that and insist on doing your own thing, you need at least one of the following in your program two or three times a week:
- Horizontal push (e.g. bench press, dip)
- Vertical push (e.g. overhead press, military press)
- Horizontal pull (e.g. bent-over row, Pendlay row)
- Vertical pull (e.g. chin-up, pull-up)
- Lower body press (e.g. squat, leg press)
- Hip hinge (e.g. deadlift, good morning)
You can do isolation movements like bicep curls as well, but try to restrict yourself to 2-3 isolation movements per session and save them for the end of your workout. Ideally, don't do any, since isolation movements are supposed to fix weak links in a lifter's movement patterns, which you don't have as a beginner since your entire body is weak.
Good luck and try not to quit before you see results.
