Fitday Question about Activity Log

[pitbullrocco]

would you consider the 5x5 workout MFW a "light workout, general" or a "vigorous" workout? i mean its not like a full out sweat or nothing

but if you pick "vigorous", it shows twice the amount of calories burned.....i find it hard to believe i burned 421 calories in an hour.

or does anyone know what fitday.com is?
