Hi Tracie! First of all congrats on your little bundle of joy! I would start off doing circuit workouts 3x a week. Taking care of your little one is a full time job (rewarding too) that you might not have anymore time than this. If you should have more time, then the other 2 days I would do cardio. I would purchase Cardio & Weights (I personally love this one) and another favorite of mine is Circuit Max. I don't know if you ordered any of her new ones but there's also Low Impact Circuit which is another goodie! I personally think you would benefit the most from buying Tracey Staehle's Core Conditioning & Strength dvd. You can purchase this at fitbytracey.com. Its challenging but will work best especially after having a C-section (I had one too but it was almost 15 years ago). Once your acclimated to getting back into exercising on a regular basis, then I would recommend you do a weight training split routine or a total body workout. If you wish to already do that, then I would recommend Muscle Max doing it 2x a week & the other days cardio (mixing up the cardio too) from step, hi-lo & kickboxing.
Nutrition is going to be 80% of the battle. I can provide you with an example of a day's worth of eating just to get you started. However, I don't know what your preferences are, if your vegan, or have any food allergies. Also are you breastfeeding?
Meal 1: steel cut oatmeal made w/1% milk w/fruit of choice or 3 eggwhite omelette w/salsa or high protein, low fat cereal w/fruit
Meal 2: handful of almonds w/fruit or lf yogurt or piece of cheese w/fruit or omelette w/salsa
Meal 3: chicken/turkey/fish w/veggie & either baked potato or yam
Meal 4: salad w/protein of choice
Meal 5: pasta (preferably whole wheat or quinoa) w/broccoli or veggies of your choice or protein & veggies
Meal 6: if your still hungry, prepare a protein shake
The idea is to consume most of your higher calories at the beginning & middle of the day. As you progress towards the night, you want to keep calories to a minimum.
And remember no white flour, white bread, pasta made w/eggs & white flour & sugar. If you need to sweeten your tea or coffee, please look into using Stevia (comes in powder form). You can purchase stevia from a health food store. I have a huge list which I can send you of protein/simple & complex carbs/dairy, etc. if you'd like.
Also I would recommend going into the pregnancy forum & asking this question to these women. Some of them have had babies & perhaps can give you better feedback on what worked for them.
Good luck! Kathy
