Kagels?  LOL  I've never actually logged them.  I don't know what they are worth. 

Seriously, what kind of work do you do?

I’m a receptionist so I’m always sitting at the phone. Would simply standing while answering the phone burn more calories?

I doubt enough to make much of a difference.  When do you get off work?  Just because you can't go to the gym doesn't mean you can't workout.  Go for a run/jog/walk/bike ride or do something aerobics-y at home. 

I wouldn't stress about it either.  

I was looking for a desk workout that someone posted a while back.  I can't find it.  I did find this for you:

After work I'm spending 4hrs in my psych class so I get out at about 8pm. Then it's a 1.5hr commute home. Hmm maybe I'll try some strength training. I have a 1000 page sociology book that's ridiculously heavy.

Time to get some resistance bands!  And I've seen desk work-outs with them on youtube.   My mil gave me some bands a while back and they've been fabulous because I can do it easily at home and they don't take up much space.   And I've noticed  a HUGE improvement in muscle tone with them.  So they are perfect for when you can't make it to the gym.

Standing while taking acalls is good, also before you sit down ehn you are a few inches from the seat hold it there for 5-10 seconds. <-- Its like doing squats :-)
