If you have several weight training DVDs of Cathe's from different series already, you make a good guess as to which exercise will be included. Do you keep record of how much you lift per exercise per workout? Just use these same exercises to work out a whole load of 1 rms.
Chest: bench press with barbell, and separately with dumbells: flyes
back: barbell rows, one arm rows, overhead extensions, deadlifts
shoulders: military presses with barbell and with dumbells, arnold's presses with dumbells, side lateral raises, front raises with plate nd with dumbells, rear delt raises
biceps: curls with barbell and with dumbells, hammer curls with dumbells, concentration curls, crazy 8s
triceps: overhead extensions, french press (skull crushers) with barbell and with dumbells, lying cross body tricep extensions, kickbacks,
legs: squats, plie squats, static lunges, walking lunges, lunges with rear leg raised on bench, sit-n-stands, deadlifts,
I am sure there is more, but start with this list and you will be pretty ready!
