well, that is my program that I have got from my PT.
you should definitely try a proven program but even if you tried to improve what you are doing right now, one thing that should ring an alarm is that you are doing a bunch if things that have absolutely no context or relation to each other, that's one hell of a frankenstein of a workout program.
you always have to question everything. what happens with more weight and less reps or less weight more reps? are all exercises equally important? (answer to this is NO!) why should I do this or that exercise? is it supposed to serve as assitance to something else (like a compound)? do I really need that at the strength level I am now? if yes, how, (sets? reps?)? is that exercise redundant with another exercise I am already doing? and many other questions, most of which are answered in the OP, that's why you should give it a try.
and damn, I always cringe when I see programs that propose static weight, stuff like "I do 3 sets, 10 reps at 40, 60, 80 lbs every week", :-(
like Sunflower says, don't be upset with the replies, just stick around and ask everything you can here. Try to educate yourself by reading everywhere about the discipline.
