The Tanita BC-545 Innerscan ought to be part of your fitness equipment if you’re extremely serious in charting your progress. This device was designed especially to assess the impact of your training routine across different parts of your body, taking note of individual body composition readings for each individual arm and leg as well as the trunk area. The BC-545 will then track the changes over time for you, letting you know if you are progressing along nicely or actually regressing after having one too many late night snacks. Those with a heart pacemaker need not apply. Overall, the Tanita BC-545 is more or less a Brain Age game for the body.
