For me, it depends on what type of exercise I'm doing. If I lift weights, I'll find that my sugars are spiked right after work out, but 2 - 3 hours later, it'll drop pretty low to like 40 - 60. If I do cardio, my sugars will drop immediately after work out. Then, I find that calisthenics keeps my sugars the most consistent. But, I change it all up throughout the week, weight-lifting 2-3 days, cardio another 2 days, and calisthenics the other 2 days. I always do a temp basal on my pump at 50%, but after weight lifting, I have to eat small snacks throughout the 2-3 hours or a full meal within an hour after work out and after cardio, I have to eat a protein bar right after work out. If that makes any sense.
