Hi Alli,
Although I'm not Cathe, you said you were interested in getting some input. I've excercised for 20 years, have 2 kids, and with the Intensity Series dropped from a size 4 to a size 2!! (My weight went UP about 3-4 pounds!!!)
Here's my advice, start slowly and develop the exercise habit. I found with kids I had to workout at 5am or a little earlier in order to be consistent (I work full time too). So find a time when you can do something every day. Even if it's a slow walk on your treadmill!! Even if it's just 20 minutes. When I switched to early mornings, I only committed to 30 minutes a day. Well, 11 years later, I'm still going strong!!
I find a workout plan that alternates weights with cardio every other day works best for me. Be sure that you start out light with your weights and don't increase too soon - we want you exercising for a LONG time - like the rest of your life!!
Here's a suggestion for the first few weeks:
Week 1 -
Mon - Circuit Syle training - Powerhour or Muscle Endurance
Tues - Cardio step video
Wed - Cardio + Weights video
Thurs - Cardio - treadmill
Friday - Circuit Sytle Training - Powerhour or Muscle Endurance
Sat - walking or easy cardio
Sun - off
Week 2
Mon - Cardio + Weights
Tues - Cardo - step
Wed - Circuit Style workout
Thurs - Cardio - treadmill other non-step video
Fri - Cardio + Weights
Sat - walking or easy cardio
Week 3 - Same as week 1
Week 4 - same as week 2
I would do the same videos for 2 weeks at a time to build up your overall body strength and get it used to working out consistently. Also, feel free to take a day off in the middle - 4 or 5 days a week is plenty - or substite a walk or bike ride just to maintain the habit!!
Finally, (I'm going on too long now), for beginners in body sculpting, most of the fitness literature recommends full body weight work for at least the first month or even first 3 months. After that, you can start doing an upper body/lower body type rotation, or a Pure Strength rotation (different muscle groups). Check out Muscle & Fitness Magazine, Muscle & Fitness Hers, Oxygen, Fitness, for good nutrition and workout information and motivation. Also, check out the rotations forum here and ask for ideas.
Remember, Cathe's workouts are tough, so take is slowly, startly light and gradually advance. You'll be strong, beautiful, and injury free!
