Just to clarify a little from what Jen hs said:
choices are:
1) total body weight training workouts, i.e. Muscle Max (MM), Muscle Endurance (ME), Max Intensity Srength (MIS) and Power Hour (PH), Supersets (SS) and Push/Pull (PP), both from the Body Blast series. These are more endurance focussed workouts (lighter weights, higher reps). As a beginner, you will gain strength with these, but as you get more used to them, you will not be so challenged strength-wise and will want to move on down the list to categories 2 and 3 type workouts.
2) Workouts that separate the upper from the lower body, i.e. CTX Leaner Legs (LL) and CTX upper body split (actually both endurance worrkouts, but very tough for all that, especially LL), both contained on the incredible and versatile CTX series, or Pyramid Upper Body (PUB) and Pyramid Lower Body (PLB) from the Intensity series, also Legs & Glutes from the Body Blast series.
3) More intense workouts that are focussed more on strength and mass gaining than mere "toning" and shaping, i.e. the Pure Strength series (PS) which has just been updated as the new Gym STyles series. There is also Slow & Heavy series where Cathe lifts the heaviest weight as for a real slow count, thus maximizing strength and mass gains. All these workouts use a slower count than is used in endurance workouts because you are lifting a moderate to heavy weight, therefore these workouts take longer to get through and are split up into 2 seperate workouts, i.e.chest and back on one tape and shoulders, triceps and biceps on the other. You can work 2 body parts on the same day (chest and back), or choose to work just one body part per day after or before your cardio routine.
Whereas with endurance you will work the whole body in 60-70 mins, here you may spend 30 mins on just one body part, hitting the muscle from many different angles to fully fatigue it.
The type of workout you choose depends on your goals and the time you have available. However, for many people starting on a strength training program, there seems to be a natural progression from starting with the total body workouts and after 6 months, progressing through to the split routines over a 3 or 5 day period.
