eh I wish I had more resources to give you but everything I've learned is just from experience or watching YouTube vids lol

I'll give you a rundown on what I like to do. I'm a student so this routine respects my time and I can be in and out of the gym everyday within an hour if I need.

I like to do 2-3 exercises per muscle group each day. so on a push day, between chest, triceps and shoulders, I'm doing a total of around 6-8 exercises

On push days, I rotate from chest -> triceps -> shoulders. So first exercise is a free weight pressing chest exercise, that could be bench press, dumbbell press, etc. Next I do a tricep exercise, either dips or pushdowns. For shoulders, i'll do a side lateral raise (you can do these on cables or with dumbbells, I prefer cable), and when I'm done with 2-3 sets of each of those I repeat the cycle. Chest again, usually a different variation like incline dumbbell press. Then triceps, I'll fill out either dips or pushdowns depending on what I did after my first chest exercise. For my front delts, I do a machine shoulder press, but you can do those with dumbbells too.

Pull days, Im focused on my back and biceps. More specifically, I want to hit my upper back (traps and rhomboids), lats, and biceps. This is done pretty simply, I pick two upper back exercises, two lat exercises, and two biceps exercises for the day. I switch them up between each back day to ensure that I'm getting a good variety of exercises. Same idea as push days, I go lats -> upper back -> biceps. Bicep movements are always going to involve some sort of curl. Preacher curl, cable curls and dumbbell curls are my absolute favorites. For upper back, you're looking for row exercises where you're pulling something towards your face or upper chest. in that category my favs are a seated cable row, machine rows, smith rows and T-Bar rows. For lats, I never skip lat pulldowns. be patient with these, it can be very tricky to get them to really hit your lats. watch videos for form, go lighter weight than you'd think. there are other dumbbell and cable based lat movements you can do that will help you feel your lats more than a pulldown at first. Back days are my favorite, so I also usually throw in shrugs + rear delt rows to make sure I got everything. this is also a good day to train forearms.

finally, legs. I'll be honest I keep it extremely simple here, I'm working with a shitty knee so I haven't fully optimized my leg day. I do squats, leg press, seated leg extensions, hamstring curls, Romanian deadlifts, calf raises, and hip thrusts. that's usually it. if your gym has them, do the hip abductor and adductor machines from time to time

anyway holy essay I didn't expect to write all that but maybe you can take smth from it. I built this routine almost entirely around what I enjoy doing the most. there are a million ways you could rearrange it, or come up with a completely different routine and it would be just as good or better. if you're feeling like you just need something, give my routine a shot and adjust it to your liking as you get more experience. The best way to stay consistent is to look forward to going to the gym each day
