She's the Sydney lawyer turned Insta-star (via a short stint on our screens as the winning 2013 Bachelorette) who's managed to maintain her high profile thanks to her sunny personality and enviable beach bod. It helps that she's half of one of the best-looking couples in the country - she and Bachelor boyfriend Tim Robards are still going strong three years after the show aired.
Currently in training for the upcoming Nike+ Women's Half Marathon in Sydney on July 3, for which she is an ambassador, Heinrich has seriously upped the ante of her usual fitness routine in the last three months. Here, she reveals exactly what she's doing and eating, plus the post-workout beauty lessons she's learnt along the way.
How many times a week do you exercise?
I'm currently working out around three to four times a week.
Can you talk us through your exercise regimen?
I'm following Nike's 12-week Half Marathon Training Program, which includes three types of workout activities a week, across Speed and Endurance, plus an NTC workout. All three help you to get fitter, stronger and faster!
How has your exercise regime changed since you started training for the half marathon?
I have definitely incorporated more running into my weekly regime and now understand the importance of preparation and recovery, something that is commonly overlooked.
What's been the biggest challenge since you started training?
Keeping the motivation that I started with - it needs to be constant and consistent.
Were you a runner before?
I use to run a lot back at school (I was Athletics Captain) and always played a lot of sport that involved running. I was a sprinter back in the day and not much of a long distance runner. Signing up to Nike women's half-marathon has well and truly taught me that I can run long distances if I put my mind to it and I'm sure this goes for many others who've decided to tackle the half!
Outside the half-marathon training, what's your usual exercise routine like?
I aim to train at least three times a week and do a variety of workouts depending on my schedule and how I'm feeling. It certainly doesn't stop when the weekend begins. I love a Sunday morning boxing session. Also, I do body pump, running, dancing, tennis and H.I.I.T classes. I've found that the more I vary my workout the more enjoyable it is for me - which is hugely important.
What's your preferred post-workout snack/meal?
I love a smoothie before or after a workout (Acai, vanilla protein powder, ice and half a banana).
Do you follow a particular diet?
I don't like to go on diets; I try to eat well the majority of the time. I think being balanced in all aspects of your life, including what you eat, is key to living a happy and healthy life.
What's an average 'day on a plate' for you?
In the morning I'll have eggs, half a tomato and half an avocado. I'll also have a glass of water and a cup of green tea with a splash of lemon. Mid-morning I'll have a skim cappuccino with 1 raw sugar. At lunchtime I'll try to have a grilled chicken salad. I'll sometimes alternate the chicken with tuna or slow-cooked lamb. For dinner I aim for something wholesome and healthy - cooking steak, chicken or lamb on the BBQ, and having that with steamed or grilled vegetables and a salad. I also like to snack on fruit and nuts. My day is not complete without something small and naughty (namely, chocolate).
Is there anything you avoid food or drink wise?
I try to stay away from excess sugar, low-fat or fat-free foods, fruit juices and excessive oils.
Do you have any workout beauty secrets to share?
It's something we all know we should do more of, something that can make all the difference but we just don't do enough of... drink more water! It's a 'secret' everyone knows. Also, it's all about what you carry in your workout bag. Some of the items I always carry are cleansing wipes (the quickest and easiest way to freshen up post-workout), dry shampoo (use before and after workout), waterproof eyeliner and mascara keeps you looking fabulous pre- and post-workout, and Label.M secret hair bands because they don't leave an obvious mark on the hair.
