Boxing Comparison

This morning I did a boxing class.  It was another chance to compare my BodyMedia device and my Basis Peak.  During the class, my BodyMedia counted 3619 steps and calculate a burn of 372 calories.  In the same amount of time, my Basis Peak counted 4064 steps and calculated a burn of 311 calories.  Yet another confusing comparison.  I have no idea what pattern there is in them!

Here's a summary of the comparisons so far:

• 500-step test: BodyMedia 469 steps and 21 calories; Basis Peak 516 steps and 34 calories.
• Run: BodyMedia 7960 steps and 460 calories; Basis Peak 7700 steps and 470 calories.
• Boxing: BodyMedia 3619 steps and 372 calories; Basis Peak 4064 steps and 311 calories.
