High Score! And questions about my heart rate.
Thursday, February 21, 2013
I'm a weird flavor of competitive. I don't really compete with others, because what's the point? They're capable of what they're capable of, and I'm capable of what I'm capable of.
To me, the best kind of competition is with Emma Yesterday. EY is the only person I compete with. I have to prove that I'm better, stronger, faster, smarter than EY every day. Lately, EY and I have been competing to see who can burn more calories in Zumba. I have totally been winning!
Monday, I burned 904 calories in 1 hour and 2 minutes. Last night, I burned 965 calories in 1 hour and 1 minute. WOO! My goal is to hit 1,000 calories burned per hour of Zumba. Which is insane. And awesome. And potentially impossible.
I have been hitting the "red zone" of my heart rate during Zumba, I think. I don't know how to feel about that, because I recover quickly and feel fine after I "come down." Everything I read says that one shouldn't exercise above 90% of their max HR, but NOTHING says what that max HR really is. There are about 1000 different formulas for configuring your HRmax and none of them agree. Spark uses two different formulas, I guess.
The "age formula" says HRmax = 220 - age. For me, that sets a max of 195bpm.
The "resting HR formula" says my HRmax is 189bpm.
Last night, my HR hit 190 at one point and hung out around that area for about a minute. By either formula, I was between 97% and 100% of my HRmax. Which is probably not great? But again, I recover quickly and feel fine afterward. I don't know if I'm damaging myself somehow, though. If anyone has any heart-related knowledge, I'd appreciate your input.
Anyway, I think I've been doing superb on the fitness front lately! On the food front, I've been a lot looser. Not always tracking, for the first time in a very long while, but only eating when I'm hungry and stopping when I'm not. So I think I'm doing alright? We'll see how that actually worked when I weigh in tomorrow, and I'll buckle down more next week if need be.
More than anything, I'm just feeling great lately. Strong and fit and capable. If I never lose another pound, I think I can accept that at this point.
