Not getting a great nights sleep? Maybe high-intensity interval training (HIIT) can help… at least when it comes to insulin resistance.

HIIT before 24 h of sleep deprivation attenuated the increase of glucose, insulin, and free fatty acids in healthy males.

Several studies show that HIIT improves glucose metabolism, increases mitochondrial biogenesis (the growth of new mitochondria), mitochondrial function, β-oxidation (the use of fatty acids for energy), and also the levels of glucose transporters in muscle cells all of which improve insulin sensitivity.
