Well anyway, the object of a full body workout is to work your whole body in each session (lasting 45-60 minutes) 3 times a week.
This is seen by many as the most efficient way for the general population to weight train.
as for two FBWs that you'd alternate doing you could do:
for workout A
squat
bench (horizontal push really, can be DB chest press as well.)
pullup
dip
bentover row
lunges
workout B
deadlift
dumbbell shoulder press (or military press)
pullups
dip
upright row
stepups
Rep ranges should change as well. Maybe do 5x5, 4x8 3x12, and change break times as well. 30 60 90 or 45 60 75.
