Pairing interval workouts with daily cinnamon boosted fitness test scores and blood irisin in cadets.

Researchers tracked forty-eight male military cadets across six weeks to test short workouts and cinnamon. One group did high-intensity intervals three times weekly, one took cinnamon daily, one did both, and one did neither. The interval training used eight rounds of twenty-second bursts with ten seconds of rest. Cadets who trained improved their deadlifts, running, and army fitness scores. Adding cinnamon to workouts triggered the largest rise in blood irisin levels.

Why it matters

Soldiers and athletes often look for ways to build strength and endurance without spending hours in the gym. This study shows that pairing very short, high-intensity intervals with a common spice can improve military physical test scores, increase lean body mass, and alter metabolic markers in just six weeks.
