heres a cool idea =
workout mon-wed-fri
each workout =
choose one = deadlifts, rows, pullovers, pulldowns (or any variation)
choose one = squats, hack squats, front squats, lunges, leg press (or any variation)
choose one = bench press incline decline or flat, dumbells incline decline or flat (or any variation)
choose one = military press, upright row, dumbell press, side laterals, front raises(or any variation)
choose one = bent over rows, reverse pec deck(or any variation)

choose one = close grip bench, dips, v-bar pushdowns, skull crushers(or any variation)
choose one = ab exercise (or any variation)
you will have a total of 8 different exercises to do. for every one, do a few sets to warm up, then do one set to complete failure.
pick a different exercise and a different order of doing all of them at every workout.
