Trainer vs. Trainer

I have a digital display for my BodyBugg that allows me to reset it for a time period. So on Thursday I decided to see how many calories I'd burn in an hour working with Saran. She guessed 250; I hit 251. Of course if this were "The Price is Right" she'd lose the Showcase by being over! Pitted her against Zak today. He worked me to 257 for the hour! Saran is going to have to see how much harder she can push me next week! Given that trainers are naturally competitive and achievement-oriented people, this could get painful....

Does that number surprise you? Would you think it would be more? For the full hour with both trainers, I work myself up to a pretty good sweat and I have to stop for breaths quite often. But while the work IS hard, what burns more calories per minute are the weight-bearing compound movements and not everything I'm doing is like that. I burned about as many calories for the two hours after my workout that I spent walking around downtown.
