[QUOTE="In Response, post: 2453489, member: 527103"] There have been many threads about exercise and the two things that come out are that overall exercise is good (and not just for diabetes) but the immediate effect of exercise differs depending on the type of exercise, how fit you are and what your levels are when you start. In general, prolonged cardio reduces levels and short stop-start exercise such as hit and weights cause levels to go up. But, if your body is stressed by the exercise, it will go up. For example, if I go for a long fast cycle ride along a flat road on a fair day, my levels will go down but if I cycle for as long up a steep hill against the wind during a rain storm, m levels will go up. I also find that if my levels are higher than 8 (we all vary), cardio exercise will stress my body and cause my levels to go up. The other thing to consider is that the reason our levels go up is that our liver is releasing glucose. The liver glucose stores need to be refilled and, as a result, even a big weight session will lead to a reduction in levels over the next 24 to 48 hours. Finally, when damage is done by being high for long periods, a fe hours is not a long period. The damage is done over days, weeks, months, ... In summary, unless you have injured yourself, exercise does not do harm but it is better to start with a lower level and you will see an immediate effect if you do prolonged cardio but intermittent and weights is also good longer term.
