Discounted supplements are easy to come by, but when it come to discounted equipment the chances of it occuring is usually slim. Supplement Central is offering a body mass calculator called TONUS made by Sequoia Fitness for $8.95. At that price it is 40% off the retail price! The body mass indicator is small and light weight which makes it easy to keep in your bag at the gym or in your purse at work. You can keep track of your lean body mass throughout the day and monitor how you are doing with this device. I’ve used BMI devices such as this one in the past and have been skeptical about how they really work, but Sequoia Fitness is a reputable product that puts out products that are known to work. For the price and quickness that it works this product is a must buy!
