Weight management
The science behind weight loss and maintaining your current weight can be quiet confusing. So here it is in a nutshell:
If you consume the same amount of kilojoules (kj or energy) each day as you burn, then you will maintain your current weight. If you want to lose a few kilos you need to consume less kilojoules than you burn. It is as simple
as that!
What is energy?
You need energy to live – you need it to move, from walking to running and everything in between. The higher intensity and the longer you exercise for, the more energy you will burn.
Your body also needs energy for digestion, muscle growth and repair as well as to pump blood to vital organs. Energy comes from the food we eat, our body breaks down carbohydrates, sugars and fats and turns them into energy. When energy is not immediately required, it is stored in our body as fat.
How much energy do I need?
To workout exactly how much energy you need each day can be quite confusing. You need to take into account many factors including your age, sex, body size and the amount of exercise you do each day. On average, a woman needs about 6000 to 8000 kjs a day, less if she wants to lose weight, possibly more if she does a lot of physical activity. However, this can differ between each woman.
Where should I get my energy from?
Different types of food provide a different amount of energy. Carbohydrates and proteins provide about 17 kjs per gram, while fat gives you 38 kjs per gram. This is why people who want to lose weight stick to a low- fat diet.
Toning tips
Okay, now that you’ve covered basic weight control through diet, you can incorporate that knowledge into your training regime.
How do I tone up?
Resistance or weight-training is one of the most effective ways to develop stronger, leaner and more defined muscles. Weight- training also helps speed up your metabolism through muscle growth, while strengthening bone mass.
Any form of exercise will tone your muscles to some extent, some more than others. While weight-training is one of the top ways to tone up you can also achieve results through other types of exercise, such as yoga, Pilates and even cardio training.
How do I avoid getting bulky?
It is a lot harder for women to increase muscle size through weight-training than men, simply because they don’t have enough muscle building hormones in their body. However, there are a few things you can do to promote firm and lean muscles.
• Use light weights for longer.
• Do 15 to 20 reps of each exercise two or three times.
• Don’t forget the importance
of stretching.
• Stretching improves flexibility, and promotes longer, leaner muscles. It also prevents injury and soreness the next day.
