Welcome back to 30 Fit Days. I hope you all got on well last week. This will be our third workout. This week we are talking about how you can increase your cardio to work with your bodyweight exercises to get the best results.

By week three you should be getting a little more used to the training and the cardio that you started with. The exercises should start to become a little more achievable each week. It's now time to take things up a notch.

One of my favoured ways to achieve this, is by looking at doing intervals. Intervals work well because they shock the body and help it burn more calories then steady state cardio.

If you can only manage a light run, that is fine, go at your own pace steadily and slowly, picking it up as the weeks go on.

Intervals can be on all cardio equipment or outside running. If you struggle with impact on joints then hit the gym cardio equipment like cross trainers and bikes, as they may feel more comfortable for you.

A few weeks into training programmes is where sometimes people give up, remember to set yourself set times to train and make sure to keep those appointments.

It's easy to decide to miss it just once but, remember, consistency is the key and like with anything else if you don't persist you simply will not get the results you want to achieve.

Sample meals


Bowl of porridge

Overnight oats topped with dessert spoonful of berries and a desert spoon of Greek yoghurt


Rice cake loaded with tomato, cucumber and a quarter of avocado


Homemade vegetable soup with torn chicken breast



Sliced apple with desert spoon of almond nut butter available from health food stores


Loaded chilli sweet potatoes.

Start by baking your sweet potato, when it is cooked spoon out the soft centre, add some homemade cooked turkey/beef chilli to the skins and cover with the mashed sweet potato and bake again for 15-20 mins.

Tip of the week

Invest in a good non-stick oil to reduce your use of oil.

Invest in a good non-stick or stone pan for cooking foods.

Many people excessively use oils for pan cooking meats and even stir-fries, adding unnecessary amounts of calories and making meals a lot less healthy than you think.

I always use a dry pan and add a small amount of healthy oil, like extra virgin olive oil after cooking, if required.

Fats may play an important role in our diet but good oils like coconut, rapeseed and olive oil should be portion controlled just like any other healthy fat, such as nuts or avocado.
