Try this, as it's helped me out in the past. Your first exercise should be the power movement, like bench press for chest, or like barbell rows for back. Warm up, and do it heavier so that u get only 6 reps out in your max set. after that, do an isolated movement involving dumbells, like incline db presses for chest, or db rows for back. Same thing here, warm up, and go progressively heavier till u only get 6 reps out in your max set. Have a good spotter, that's important too. Then jump to the machines to force the muscle to work. Keep it about 8-10 hard, or forced reps on the machines. And if u like, u can finish with squeezing movements for shape, and lines on a cable machine. Keep the reps high, but hard. I'll give a split example for this routine. Let me know what yous guys think.
