ok, soooo, lemme get this straight:
i can : work less during cardio to reach a certain heart rate where more fats are burned than carbs/glucose...(roughly 145 if i do the math correctly, or really, barely above a walk, about 2-3 mph on an elliptical) but this doesn't burn as many calories period, just that more of the calories burned are from fat..
i can go above this rate to the anaerobic state and burn more calories, but it's mostly from glucose/carbs, but the same amount of fat is burned as in the lower intensity workout, just not as high of a percentage..
right now, i'm working between 160 and 170 bpm for 30 minutes and 5 minute cooldown (28 yrs old, max heart rate should be about 180-190, but at 160-170, i am not panting for air, just breathing slowly and deeply, sweating a good bit, but can still talk/hold a convo, so i'd consider it fairly safe based on what i've read) after that, it's circuit stuff for 30 minutes, with the weights set in each cat so i can do 3 sets of 10-15 with my muscles totally failing near the end of hte third set. so far, i'm still not really sore, though.
Also, should it be cardio first then circuit or circuit, then cardio?
....this is all just so new to me
thanks for everything, you've given me a lot to read/absorb..
