Looks pretty decent compared to other programs that beginners come up with. Whats the plan though? Make sure to use progressive overload ( adding weight or reps) heck, if you wanna do your program for a while and you like it then yeah go for it. The best gains you make is when you’re doing something you enjoy and giving it 110% rather then 50% half assed on something you dont like . I train doing my own programming and it isnt the best way since im still a newbie lifter and not that much programming knowledge but heck i like the freedom and then if i dont progress then i can t blame any program i followed because itl be my own fault . Anyways here are some good 3 day a week programs if you’re looking to follow a structured plan.
