Cat,
If you're doing an hour on the stationary bike and a half hour on the weights you are NOT sedentary.
The ****** numbers are complete nonsense, save your time. Just eat the 1600 calories and do the 1.5 hour workout for a month and ascertain for yourself how much weight you lose. If not fast enough, or not at all...go to 1400 calories; if too fast, go to 1700!
There is no substitute for personal experience.
And I repeat, those ****** calculations are preposterous...everybody comes up with super high numbers for maintenance and then is amazed their bodies don't respond the way ****** says. Also don't believe the calories on a Lifecycler...always too optimistic (Hey, a high number sells more expensive bikes!

)
