Opportunities for Health and Fitness Professionals - jobs in gyms

Your BMI is a useful measurement for determining your correct weight for height but has many limitations and should be used with other measurements to get an overall picture. For example, body builders have been seen to have BMIs of 35 and upwards which would indicate obesity when clearly they are not.

 Believe it or not, most people are overweight and many of those are becoming obese. When we lose weight we need to know if the loss from body fat, muscle or water. If we lose body fat as opposed to muscle and water, our bodies become healthier and more efficient as a result.

What % body fat do you think is considered as healthy? 10%, 25%, 40%? What is considered healthy depends on age and gender because as we get older our metabolic rate slows and we accumulate more fat. Some slim people would appear to have low body fat levels. Having tested groups of thin people, we discovered some of them had excessively high body fat levels. When asked t about their lifestyle, those with high levels told us they did very little or no physical exercise at all.

Many go to the gym and complain saying "I haven´t lost much weight". When we tested them, we found that they had increased muscle. This was because the density of muscle is greater than than body fat meaning the weight change was small but overall their body composition had improved. 

There are many methods of losing body fat: Diet, physical exercise together with a whole range of muscule toning therapies are available. If you are trying to lose weight or improving your fitness, then monitoring your body composition changes before and overtime will show you how you are progressing.

You may think your body fat level is average or low because you are thin and within your normal body weight range. You may be wrong. Many people have elevated body fat levels who are within their acceptable weight range. Excessive calorie consumption and lack of physical exercise contribute to excess body fat which accumulates over years. It finds refuge under the skin and between vital organs. 

You can measure your body fat using bio-impendance technology. It measures body composition including your total body fat. The BIAcheck body compostion analyser is portable and lightweight which allows you to test anywhere. It measures from hand to foot giving you a full and complete body measurement. Follow up tests are easy because you can retrieve a client´s file prior to testing. Locate the file, change the weight and and re-test. It´s that simple. It takes less than 2 minutes. It will give you results of other body parameters too such as BMI, body water, BMR, total calorie expenditure, waist/hip ratio, waist/height ratio and much more in order to give you a global view of your body. In addition it gives you a "normal" range (based on age and gender) so you can compare your results. You can also set personalised body weight and body fat goals. It calculates the changes necessary in fat and weight to help you get fitter and healthier.
