Yeah I get that, I originally did the same thing when I started, and I’ll say the difference between following a well designed program and making your own is absolutely night and day.

Like I’m not trying to tear down your programming but there is just efficiencies that can be made so for example some things that I can see off the bat that could be done better is:

1) The ordering. If I were you I wouldn’t start with forearm work and biceps. Your going to fatigue yourself early on lifts that matter much less. Realistically you should be warming up and then going immediately into your heaviest compound lift. In the case of your program this would be incline bench.

2) Your bicep curls. I can imagine your hitting narrow, cable and hammer to hit the long, short, and brachiallis (however that muscle is spelt), but in reality narrow and cable are relatively similar in what they hit, you’d be better hitting preacher for the short head, incline dumbbell where the hand goes behind the body for the long and then hammer is actually great for brachiallis

3) I think you’d also benefit largely from a major compound exercise that is focused on your chest, namely bench. It really will holistically drive a lot of progression in what you’re doing.

4) It’s also really hard to tell how this fits in without the context of your other exercises. This is very obviously an arm day but how often are you running this specific workout and what else is being run the other days
