You may want to start recommending exercise snacking, particularly for people who believe they have no time for training. A few minutes of vigorous stair climbing, spread out in three bouts per day, three times a week, improved cardio fitness in formerly inactive young adults. McMaster University and UBC Okanagan researchers in British Columbia conducted the 6-week study.

“We know that sprint interval training works, but we were a bit surprised to see that the stair snacking approach was also effective,” said study author Jonathan Little, assistant professor at UBC Okanagan. “Vigorously climbing a few flights of stairs on your coffee or bathroom break during the day seems to be enough to boost fitness in people who were otherwise sedentary.”
