The muscle exercise in the legs is extreme (and provides my heart the most benefit) but I find my
blood glucose levels do not behave at all as they do when I exercise normall). I begin exercise with a BG level of 130-140, and end with one of 280 to 340 on a hard riding day. On a less strenuous day, I consume 16-20 ounces of O.J. and barely keep above 100. I will be modifying my routine with mid-ride blood checks from now on. Thank you, Yumin, for the observation and you, LRS, for the insight.
