Type 1 and Intense exercise while on Dr. B

Hi, I’ve done p90x 5 times and I’m a type 1 on insulin pump…I’m fairly new to Dr. B’s way of living, not quite there yet, been eating around 40-70 grams of carbs per day…My husband and I are both p90x graduates!! we love the program. I find my BG unpredictable with heavy exercise… sometimes it plummets and sometimes it goes high…I just have to watch it. (I have a cgm).
