> If anything, I’d say I never really know what to expect after exercise. If I knew I would crash every time, I’d have an easier time coming up with a plan. Since you asked, I assume you have a system?? Do you have any suggestions for handling blood sugar prior to, during, or post exercise?? I’m doing a lot of tests and slowly figuring out some things that work, but I always love to hear others’ ideas.

It depends on what you are doing, and what energy system you are using. Eventually you can figure out what will happen for you. It will depend on many things - workout duration and intensity, carb intake, IOB.

There is never a single answer that works for everyone. It is very personal. We can work through some things if you want. Insulin dosing and basal adjustment formulas are unique for each of us. Pre-fab solutions do not work well.

If you want to open this can of worms, here is what I would ask:

- What type of exercise are you doing?
- How many times per week are you exercising?
- What is the workout intensity? Is your heart pounding or only slightly elevated?
- How long are your workouts?
- What is your current fitness level?
- What is your current type of diet, in terms of carb intake? Low, medium, or high? Just ballpark your average carbs in a day .
- I am sure you have mentioned this before, but just to get all the stuff together on a thread - do you use a pump or MDI?
- What time of day are you exercising?
- How soon after a meal do you exercise?

Just answering those questions is a workout by itself!

Before any of that, have you read through some of the sports wiki’s?
