Bg rise after HIIT workout

As I’ve upped my exercise regime I’m now doing a 40min HIIT workout with heavy dumbbells thrown in
Noticed it was rising my blood sugar so I started taking an injection before the workout (4 units in the muscle)
I haven’t been over 200 in wks keeping within my target of 150 and 80 but I got this one today - I started at 82 - I’ve eaten nothing since 2pm - I guess my liver just felt i needed to dump all the sugar it had !!


That’s a sign of an awesome workout!
