What is Metafit?

What is Metafit?

Many people have asked this question so here’s a bit about the science behind Metafit.
Metafit uses the principles of Tabata training or High Intensity Interval Training (HIIT) as it’s more popularly known as. Tabata comes from a study carried out in 1996 by Japanese scientist Izumi Tabata and his colleagues to compare moderate intensity training with high intensity training. They took 2 groups, one group working at 70% intensity (the fat-burning zone) for 1 hour, 5 days a week for 6 weeks...
The other group worked at a much higher intensity (170%) for 4 days a week for 6 weeks. They’re workouts lasted just 4 minutes and involved drills of working for 20 seconds with 10 second recoveries.
The results of the study were incredible. The group performing the moderate intensity workouts made improvements to their cardiovascular fitness but little or no difference to their muscles. The group performing the high intensity workouts made slightly better improvements to their cardio fitness than the other group and also enjoyed a 28% increase on their anaerobic capacity (muscles).
What this means is that while long distance running, cycling etc will improve your fitness and body composition (fat loss) but it will take a long time for it to happen. It will take around 15-20mins at least to get your heart rate up high enough and you need to maintain that for at least an hour to make any significant difference. HIIT will get you better results in a much shorter space of time....
Not only that, but this style of training will raise your metabolism meaning that you will continue to burn calories long after the workout has finished. Raising your metabolism will improve your ability to burn fat.
Metafit classes last 30 minutes and uses body weight exercises which target the largest muscle groups in the body for greater effect. There is no need to use any equipment. This is not an endurance class so there’s no need for you to pace yourself to avoid looking like the least fit person in the room. Everyone should be putting in their maximum effort.

Change Your Body Composition

 
Do you want to lose weight or do you want to lose fat? Most people who diet and exercise want to get rid of flab, but keep lean, tight muscles. They want to change their body composition. To do that you've got to create a workout plan with the right combination of exercises.

 Change Your Body Composition

What is Body Composition?

Body composition is your body's ratio of fat to lean mass, including muscle, bones and organs. Body composition is evaluated using body fat percent. A fit woman's percent body fat is generally between 21-24%. A fit man's body fat generally falls between 14-17%.

There are many ways to measure body fat percent. Many health clubs and doctor's offices can perform simple tests to get the number. There are also body fat scales that measure the percent. Before you start an exercise program, it's a good idea to know your number so that you can measure your progress along the way.

Keep in mind that when you exercise to change your body's shape it is possible to see your weight increase or stay the same, even though your body is getting smaller. The reason for this is that muscle weighs more than fat. As you lose fat and gain muscle, the net result may be a small increase on the scale.

How to Exercise to Lose Fat

All forms of exercise burn calories. Even non-exercise activity burns calories. But what is the best way to burn fat? Aerobic exercise will do the trick. Aerobic activity, sometimes called cardio, is exercise that gets your heart pumping. During an aerobic workout you'll breathe heavier and begin to sweat.
It is not necessary, however, to exercise to the point of breathlessness every day. For most people, the most efficient fat burning occurs at a exercise intensity, but as a general rule, moderate intensity would rank as a 7 on a scale of 1-10.

However, as your fitness level improves, you want to include harder workouts as well. Higher intensity workouts burn more calories, but a smaller ratio of fat. To maximize fat loss, combine high intensity, moderate intensity and low intensity workouts into a complete and balanced program.

Build Muscle With Strength Training

For many people, the real change to their body comes when they begin strength training. While strength training might make your heart pump faster, it is not considered an aerobic activity. The purpose of strength training is to build and shape the muscles.

A common misconception among women is that strength training will cause them to bulk up. This is rarely the case. Women don't make enough of the hormone testosterone to build the muscles that a man might build doing the same workout. So grab those weights, ladies, and get pumping!
Starting a strength-training program requires no special equipment and doesn't mean that you have to join a gym. Simple body weight exercises are effective. For example, combine push-ups with variations of the lunge and abdominal plank exercises, and you will build strength in all of the major muscle groups of your body.

Change Your Body Composition in Less Time

The best way to lose fat and shape your body in a short period of time is to combine aerobic activity with strength training. You can do this in a single workout with circuit training or alternate workouts from day to day.
  • Circuit training. Combine your favorite cardio activity with strength training and alternate each activity within a single workout. For example, if you like to walk you might get on a treadmill and climb a hill for 7 minutes then follow up with 3 minutes of push-ups, lunges, and abdominal curls. Repeat that pattern three to six times for a complete circuit workout.
  • Alternate days. You can also burn fat and build muscle by alternating workouts on different days. For example, you might choose to take an aerobics class on Monday, Wednesday and Friday and complete your strength-training workout on Tuesdays and Thursdays. Try not to schedule strength-training days on consecutive days as your muscles need time to recover.
Don't forget that changing your body composition takes time and the most important element of your workout program is consistency. To keep yourself on track, set a long-term goal for your desired body fat percent, but remember to set short terms goals and reward yourself for staying committed to the program.
