My routine is to target my
heart rate 145-150 and up to 162 during the middle 10 minutes. Lately, I have noticed towards the end of my workout, during the cool down, the last 10 minutes, I begin to feel lightheaded...I get the strobelight effect in the middle of my vision, and my entire field of vision begins to darken somewhat. At first, I thought this is near syncope, but recently I had a severe occurrence which my instinct told me to take my blood sugar, so I do and it was 39.
