Between this and your "humble-brag" on your other post, what I'm led to believe is that you're pretty ignorant on how variable insulin sensitivity and blood sugar management is from individual to individual.
I've maintained an A1C of less than 6.5 for more than a decade so I'm the picture of "perfect" control and I can tell you that physical activity is a pain in the ass. I'm hypersensitive to insulin during physical activity. When I go to the gym I want zero insulin on board because just 10 minutes on the treadmill could drop me from 160+ to 30. Just walking is enough to cause me to have low blood sugars, so I have to reduce or skip insulin with food accordingly. I'm required to elevate my blood sugar to 200 before I can scuba dive and then I can still only dive for a maximum of an hour because there is too much risk I will pass out and drown.
And then you say, "I am dealing with an issue where I think some of my preferred injection sites are becoming less effective". Preferred injection site? WTF dude? Of course it is becoming less effective, that is why they tell you to constantly change the location. Preferred injection sites are a huge no-no.
