My suggestion is to ease back into things and test very frequently so you can get an idea of how your levels are affected by each type of exercise.
-Generally, we're more sensitive to insulin when working out and most people have to adjust their insulin accordingly before exercise.
-Many people also find that certain types of exercise may cause them to spike at the beginning of a workout while other types of exercise may not cause initial spikes.
-Consistency is very important in my opinion. To avoid frustration, you don't want to reintroduce EVERYTHING all at once because there will be times when you go high/low. Eventually, when you get a better fell of things, you can get back to 100%, but ease back into it.
