BMI (body mass index) has traditionally been the value used to measure a healthy weight for a client’s height. But it is not able to distinguish body fat from muscle and water; essential in helping a member or client reach their goals.
BIA (bioelectrical impedance analysis) does provide this distinction. It allows you to determine if a change in a person’s total body weight is due to fat, muscle or fluids.
This more specific data allows you to adapt a wellness or fitness program very early on, helping members and clients to work more efficiently and achieve their goals much faster. This increases a person’s motivation which can in turn increase referrals and ultimately increase the number of members or clients.
Stuart Jackson, Director of Sales (UK & Ireland) at HaB International , said:
“BMI has been in use for over 100 years, but came under scrutiny when a study1 found that using BMI incorrectly labelled more than 54 million Americans as “unhealthy”.
“We’re now being asked by our customers for devices that will accurately measure far more than just BMI, and BIA technology from Bodystat does do that.”
“In fact, gyms, clubs and personal trainers are increasingly wanting to provide as much detailed, accurate data to their time-poor clients and members in the quickest time possible, so BIA is really taking off.”

BIA is non-invasive. It uses a small current to measure skin resistance at different frequencies against various tissues in the body. Accuracy of measurement depends on the thickness of the skin and the connection to the electrode on the skin. For instance, your skin is thicker of on the soles of your feet than the tops of your feet. For this reason, leading BIA and fitness assessment manufacturer, Bodystat, use calibrated, medically graded electrodes on top of the hands and feet, rather than stand-on scales.
Before the invention of bioelectrical impedance analysis (BIA), BMI used the measure of the client’s weight (kg) divided by height, in meters squared. However, these values cannot pinpoint the reasons for specific fluctuations in total body weight. For instance, loss of weight doesn’t necessarily mean the client has lost fat. It could be due to loss of muscle or even dehydration.
“The Bodystat 1500 has been tried and tested in gyms for over 20 years and users find it an invaluable tool for motivating their clients and getting real long-term results,” said Stuart.
Bodystat devices, such as the 1500, with their advanced body composition measurements, offer accurate, medically graded results in seconds and are equivalent to Gold Standards. Bodystat has a thorough understanding of BIA technology and HaB International are their official distributor for the UK.
