Brief stair-climbing exercise snacks lasting 15–30 seconds, performed 8 times once per hour during prolonged sitting
Exercise Snacks
Stair-Climbing Exercise Snacks and Post-Meal Metabolism
Two randomized crossover studies tested hourly stair-climbing exercise snacks during a 9-hour sitting period. Insulin and free fatty acid responses fell in adults with overweight or obesity, but not in healthy-weight men.

Intervention
Main findings
In healthy-weight men, stair-climbing snacks did not significantly differ from sedentary sitting for insulin, glucose, NEFA, or triglyceride AUC. In adults with overweight or obesity, they lowered total insulin and NEFA AUC, while glucose and triglyceride AUC did not differ.
What this may mean in practice
Snacksmate's reading of the evidence — not a quotation from the original paper.
The findings suggest that hourly brief stair-climbing breaks during prolonged sitting can improve post-meal insulin and free fatty acid responses in adults with overweight or obesity, but the study did not establish the same effect in healthy-weight men.
