Spiking during/after exercise

I know that many diabetics worry about their glucose levels dropping too low during/after exercise, but do any of you experience the opposite problem? It seems that this is a problem that I have as of late. For example, this afternoon I spent a little more than 90 minutes working in my yard, mowing the lawn and taking down a small tree with a chain saw and moving the debris to the curb. When I tested immediately upon completion, I was at 166 - an extremely high number for me. An hour later, after showering and relaxing a bit I re-tested, and was at 85.
I don't know if this is normal for me and I just didn't know it because I usually haven't tested immediately after exercising, but have been testing 6-10 times per day the last couple of weeks as I've been coming of Metformin. My fasting and postprandial numbers have been great, but my after exercise numbers have been elevated. I don't know if this is something I need to worry about or not.
Does anybody else have this issue? If so, what can be done do prevent it from happening? Any ideas would be welcome.

This used to happen to me a lot. It seems as my body has adapted to my increase in exercise it happens less and less. So your body may be adjusting to no met and exercise. I would give it a while to adjust. I have always figured that even if it went up for a bit the long term benefits of the exercise outweighed the short term risk of the high.0

Could this have just been a false reading, maybe a bad test strip. I would recommend if it happens again to take a second test, maybe use a strip from a different container.
Just a thought.0 -
This happens to me as well I noticed it happening if I wake up and workout before breakfast. Probably would help to eat something small prior to working out. I think if it falls after rest you really shouldn't worry about it. I have been doing fine and I have even lost 65 lbs.0

I doubt it was a false reading as I've been noticing a pattern over the last week to ten days. It could be that I've always been like this and never noticed because I rarely tested after exercise, or it could be my body adjusting to coming off the met, as Sharonks mentioned. The 166 just startled me because I haven't seen a number that high since the first couple of weeks after diagnosis. I'm not too worried about it because it came down to normal within an hour, but it is something I'm definitely going to keep an eye on.0

I actually asked my Dr about this the last time I was in as I started noticing it too. She said it's normal because when you are exercising your body secretes more glucose to help keep your body working. She said as long as it comes back down in 60 - 90 minutes it was OK. BUT with you coming off the Met, I would keep a close watch.0

When I first started exercising again after I'd been laid up for months with health problem then surgery I would spike to 160 to 230 doing circuits for 20 minutes. Now here I am about 4 months later and in much better shape. I took my BG after running 6 miles and then doing a cool down walk for 1/2 mile and it was 92 down from 115 before I started. I think you will probably adjust too.0

When you begin a new exercise program or change up on the type of exercises you have been doing, going from biking to running as an example, you body is basicly in shock and calles on the liver to produce more glycogen. Once the body gets use to your exercise routine, it will moderate the glucose production to match what you normally do.
I began doing HIIT and HIRT (High Intensity Interval Training/High Intensity Resistance Training) after spending a couple of years doing fast walking only, which my body was use to, my blood glucose levels would jump to 250 within 25-40 minutes then drop like a rock in the next 15. There are books that explan this and give you the reasons why this happens. If you are doing low intensity aerobics, walking 3/4 mph, this doesn't happen. It is when you are doing high intensity workouts or you are doing something new that your body is not use to.0
