Last night I was determined to get at least 90 minutes on the bike for the second half of the days workout. Since the Bike Rack closes at 7:00, I needed to get there and be set up by 5:30. No problem, I climbed on the bike at 5:30.
Ten minutes later my heart rate was still low. Just over 100bpm which is not even Zone 1 for me. No problem, I will just focus and work a little harder. 120bpm was all I could manage. Normally, once I am warmed up my heart rate settles in to 138ish. Not this time. I was struggling to keep the heart rate about 100bpm.
If I didn't have a heart rate monitor I would have thought I had a good workout. I was still pushing hard, sweating, and spinning my pedals at a good cadance. The only give away was my gear choice which was very low(easy). As soon as my computer read 1:30hr, I climbed off the trainer, packed up and headed home.
I am not quite sure what I accomplished sitting on the bike in such a condition. The only good I see in sitting on the bike last night is that I burned some calories. I don't know how and if it contributed to my fitness.
