Welcome to a whole new world, a whole new universe even. In the first three weeks post birth everything is a blur – here’s my approach to getting through it.

Week 1

You are not going to bounce up off of that hospital bed and jump on the treadmill. The opposite in fact. This is your most important time for healing and milk production. So here's your big goal for this week – DO AS LITTLE AS POSSIBLE. Sleep when baby sleeps, eat protein and carbs every time you feed the baby and just make milk. Know deep down that the pounds are literally dropping off you this week, purely because you're feeding and recovering from birth. Also, you'll probably cry a lot that's gotta be a core workout ;)

Week 2

By now the birth fog has probably started to lift slightly. You may be starting to remember what a barbell looks like, and worse – you're probably starting to remember what you looked like before the baby wreaked havoc on your six-pack. But seriously – the baby fat is there for a reason! That's what your baby's going to eat for the next few weeks or months. Love it, cherish it and don't try to get rid of it yet. A few short walks with baby in the front pack will make you feel more like a human, and give you just a few lovely endorphins to work with.

Week 3

Okay, so if you're like me, by week three you're getting a little desperate for a workout... The key is to TAKE IT SLOW. Check out the free online workouts for new moms here. But remember, rest is still your priority, and exercise still shouldn't be interfering with it. A great thing to focus on is nutrition. My goal has become to make sure that every single thing I put in my mouth has serious nutritional value. I call it my superfoods eating plan and it keeps me feeling awesome. Focus on lots of lean protein, loads of colorful veges and good fats like avocado, nuts, seeds and coconut oil.
