The vertical demand of stair climbing means you can skyrocket your heart rate (the key to scoring HIIT’s cardio benefits) and reach an off-the-charts calorie burn: Running stairs burns 484 calories in a half hour, compared with 393 calories if you run a speedy seven-minute mile. “Moving your body vertically takes more power than going across a flat surface,” says Martin Gibala, a kinesiology professor at McMaster University in Ontario. Can’t last a half hour? Even one minute on the stairs will raise your game. In Gibala’s recent study, by doing just three 20-second bouts of vigorous stair climbing – with a few minutes’ rest in between – three days a week for six weeks, participants saw a 12 percent increase in their cardio fitness and an 8 percent increase in leg muscle power. He suggests varying your interval workouts: Start with three 20-second efforts; next time, try six 10-second climbs; another time, do four 30-second climbs.

Facing away from steps, place top of right foot on first step. Bend both knees (shown) until back knee almost touches the ground. Return to start. That’s 1 rep. Do 10 reps. Switch sides; repeat.
Start on ground in plank on palms with steps in front of you. Walk 1 hand at a time up to the first step, then the second, maintaining plank position (shown). Reverse the movement back down to ground, 1 hand and 1 step at a time. That’s 1 rep. Do 10 reps.
DIP & REACH
Sit on the bottom step with knees bent and feet flat on the ground. Place hands on edge of step with fingers pointed forward, then lift butt so it hovers just above and in front of step (shown). Bend elbows to lower butt toward ground. Push back up. Straighten left leg as you reach right hand to tap left foot. Return to start. Repeat left. That’s 1 rep. Do 10 reps.
4 FLIGHTS That’s how many sets of (14 to 16) stairs you should be able to walk up in about 40 seconds without stopping if you’re in shape, says Dr Jesús Peteiro-Vázquez, a cardiologist at University Hospital A Coruña in Spain. It’s the equivalent cardio fitness benchmark he found by treadmill testing over 12,000 people in his new study.
Make it a double, sometimes
For a bigger body payoff, should you hustle up the stairs one at a time or skip every other step? In terms of total calorie burn, the former is slightly better, according to a study from the University of Roehampton in London. “But the difference between the two is not substantial,” says lead researcher Lewis Halsey. “Try varying one- and two-step climbing, either during one stair climb or from one stair climb to the next, because these two strategies are likely to activate leg muscles in different ways.” His caveat: Always descend one step at a time.
