Type 1 Spin class

Before the pandemic, I was a frequent spinner (3 or 4 times a week).
My experience was a drop in blood sugars even when I had no fast acting insulin on board.

But, we are all as different as spin classes are different.
It is not unusual for HIIT to cause a rise in blood sugars and some spin classes are more HIIT-y than others.

During the pandemic, I have been doing Zwift workouts which are the closest I can get to spinning at home, This definitely causes my blood sugars to plummet but it is more endurance than most spin classes so I am not surprised.

I recommend persevering. If your blood sugars alway rise, take some insulin before you start (climbing makes my blood sugars rise so I take enough fast acting insulin to aim for 3mmol/l knowing I will never get there) but always keep hypo treatment close to hand.

Hi SareN

I did the Dafne course quite a few years aogo and they went through exercise and suggested you needed to active insulin in your body otherwise you may wise during exercise.

I use to have lunch at 12 noon (with injection) and nothing else then go to a class around 6pm check beforeclass everything was great but after class quite often high like yourself. At the course it was suggested i eat later than 12 noon so i slipt my lunch ate part at 12 noon (with injection) and then ate the second part at 3pm Iwith injection). At the time it worked and a rise didn't occur, they were cautious about injecting a unit before the class as for me it was not always 100% I would rise.

But as everyone says we are all different so you need to find what works for you.
