Terrific workout this morning. I use the curves smart system, which tells me when I'm pushing hard enough, or if I'm slacking a bit. that's good, because each machine can tell me whether I'm using enough energy to get the best workout. It's nice, but I'm not pinning a lot on it, because the past two workouts, there has been one or another machine on the fritz. Last time, when I looked at my workout synopsis, it gave me a very poor rating on one muscle group...because that machine STOPPED WORKING while I was on it.
And today, a different machine was giving me inaccurate ROM information.
Thing is, I know in my body when I'm going strong. I can feel it, and I like it. So, the system will keep me going strong with each machine, but I'm not gonna fret over whether the workouts look perfect or not. At the end of the day, it is how I feel physically that will show me how I'm doing.
Curves also recommends keeping your heart rate between this and that percentage, and i agree with that policy EXCEPT it isn't bad to get into the higher ranges briefly.
I think the idea is, you aim for a range, where more fat is burned. The numbers I've seen are 60%-70% for maximum fat burn. However, pushing it hard and getting into the 80-90% range (the anaerobic level) is very good for your heart, and there's nothing wrong with getting there in the course of a workout. Not staying there, of course...your calories burned aren't as much from fat in that range, but you're strengthening your cardio and respiratory systems incredibly.
Also, thinking about which level makes me feel good all day long, i have to say the higher intensity offers more long lasting "feel good"... is that endorphins? anyway, I do want to burn fat, and that happens at the 60-70% range, but I also want to feel REALLLY GOOD all day long, and the 80-90% range is what does that for me.
so if my heart rate gets to the 85% range once or twice in a workout, I like it.
I have a feeling the same thing is gonna happen to me that happened in 05-07, when i was really pushing fitness, and that is: my heart will respond quickly, so that it takes more and more pushing to get my heart rate up BUT my knees (and other joints) won't take it.
Last time, I ended up doing some running, just to get my heart going. I also joined a fitness club and did their Body Pump classes LOVED IT! and even some Boot Camp (hated it, but did it anyway) It seems, working out makes my heart younger, but my body won't get younger
So, i dunno. Maybe I'll work the curves workout at 60-70% and just burn fat, and my heart will benefit. I am looking forward to seeing definition begin to show
sexeeeeey!
