The BC-545 uses advanced Bio-electrical Impedance Analysis (BIA) to analyse body composition, calculating your body fat, muscle mass, hydration level, metabolic rate, visceral fat and bone mass. With this information easily at hand, you can fine-tune your diet and fitness programme to ensure optimum results and help prevent injury. This ingenious device is so technically advanced; it uses segmental BIA analysis to provide an in-depth breakdown of each body segment - namely your arms, legs and abdominal area - allowing you to specifically track changes to your body fat and muscle mass in targeted areas as your training programme progresses. Segmental readings are also particularly important when recovering from injury. By tracking muscle build and balance you have access to vital information that can help you to monitor your progress during the rehabilitation process and speed up your return to peak fitness.The BC-545 will also help you to monitor your body composition and maintain your fat and muscle percentages at a level that ensures optimum performance. Giving you a baseline to work from, you can regularly assess the effects of your training regime. Whilst your overall weight may not alter, you may start to see changes to your muscle mass and body fat percentage that will give you the motivation to keep on challenging yourself and upping your game.
