I typically do 1 body part per day, and 4-6 exercises (depending on time, I may "Super-Set" 2 exercises together) for that particular muscle group being trained.  I do  a "WARM-UP" set with my first exercise, just to get the blood flowing and get the muscles warm. The last thing you would want to do is start lifting "COLD" and pull or strain a muscle, which could eventually put you out of commission, and also cause severe injury.  I then proceed to perform 4 sets of each exercise, coupled with REPS ranging anywhere from 12-15, 10-12, 8-10, and 6-8 on the preceeding set​.  I constantly increase the weight as I move on to each next set.  I rest anywhere from 45-60 seconds in-between sets just to keep my heart rate up and keep the pump flowing.  So to sum it up, each body part will receive 17-25 TOTAL sets, and there will always be some form of Cardio or Abdominal work afterwards.​
