HIIE significantly improves insulin sensitivity and lowers fasting insulin levels, with effects lasting up to 72 hours post-exercise in some protocols.

For individuals with insulin resistance or Type 2 Diabetes, incorporating short bursts of high-intensity cycling (HIIE) can significantly improve how your body handles insulin, potentially reducing medication needs or improving metabolic health. This benefit appears to last for several days after the exercise session.

HIIE also significantly lowers insulin resistance and results in a number of skeletal muscle adaptations that result in enhanced skeletal muscle fat oxidation and improved glucose tolerance.
