Here is a biogenix rx breakdown that can help guide you to your decision: You should do a full body workout if: You are brand new to working out For those who are new to working out or are starting back after a very long break, full body is best. Your muscular endurance is low and needs to be built back up. Most people will see plenty of results in the first 2-4 weeks with just 1-2 exercises per muscle group. You are inconsistent in following workout plans The last you want to do when doing any sort of fitness program is to create muscle imbalances due to inconsistent training. If you start out with body part splits (Chest/Triceps one day, Legs next, etc... ) and you start missing workouts, you put yourself at risk of developing muscular imbalances since not all of your muscle groups are being trained the same.
