Looking for a plan

I am looking for exercise plan. Something I can do from home. Have barbell at home, but not much more.

Current problem - I only know few moves that I can do. So I am going to be sore all over the body next day (befinner, but now the theory 3 sets 10-15 reps, eat much protein) and cannot do much next day :(

Would like to opt Like daily morning exercise 30 min and vary between muscle group so legs can rest the day I am building arms amd etc. However currently I know like squats, situps, plank, push ups, pull ups (don't have anything to pull myself up at home) only.

Long time ago a friend showed me various moves, Like how using weights you can target different muscles in arms, do you would have "full arm workout", but I really don't remember.

Anyone knows a good place, like what has maybe a pre existing exercise plan, or what has att least info about exercise moves with filter option "have flour amd some weights at home". Or maybe some app that helps (either free or low cost)

Thank you for your help! :)
