We did 32 min on the spin bike ( 30 min / 2 min. cool down to about 99 bpm.) I set the target window on the heart rate monitor at 110 to 130, with a mid-range objective of sustained 120 bpm. It takes some 5 min. to reach 100 bpm, and another three min. of serious effort to get to 110. I was able to get at 126 bpm, but can't sustain this rate and slip back to about 122 or 120. It's easy to slide under 120.
Today -- Tuesday, April 4, 2011:
32 min. on the spin bike. (30 min. / 2 min. cool down to 99 bpm.) It's taking 5 min. to get 100 bpm. Resting rate of approx. 74 bpm, and a starting rate of approx. 84 bpm. Lots of effort required to reach 110 bpm, and at that rate I waiver back down to 107 bpm. We crank up the resistance and stand/pedal for 30 min to reach 120 bpm, but it slips back to 117 bpm. I was able to reach only about 122 bpm today and then only briefly before slipping back under 120.
We can't decide if this is evidence of better fitness -- and so lower heart rate during effort. Or is this evidence of lack of recovery -- and so inability to reach target heart rate at a specific perceived effort?
I'm feeling fit, looking fit. Weight is at 216 to 218 lbs. 38% to 42%
We're looking for some longer hikes . . . extended walks, and get out of the "rut routine."
