Before I start I want you to know that this isn't your fault. OK? It's not.
But...
NOOOOOOOOOOOOOOOOOOOOOOOOOOOOO. It's NOT ok. Don't do this! No. No. No. Don't even think about doing this.
No.
Get it? No, I don't think you get it. Don't do this. EVER.
As someone who wasted months of "working out" doing crap like this, I can tell you that you will have minimal gains at best, and chances are that you will be extremely discouraged when you don't grow after three months of this. Trust me. Start with the compound lifts and progress using those. I used to do 4-6 different types of accessory exercises on my chest days to "speed progression up." No. Waste of time. Stupid. Idiotic. No, just no. I used to do incline dumbbell bench, flat dumbbell bench, triceps rope pushdown, dips, machine flyes, single arm tricep pushdowns, seated tricep extension machine, and sometimes I'd even throw in decline barbell bench. I was dumb. Now I do some tricep rope pushdowns to warm up my tri's then warm-up with my barbell bench press or incline dumbbell bench and go to work. I'm finally seeing solid progression on my lifts. So...
No. Don't do that.
