Here’s how it works: Do each exercise for 30 seconds. Perform as many reps as possible with good form. It doesn’t matter how big your flight of stairs is; just go for time. After the first time through, rest for 2 minutes. Repeat the entire circuit once more, and you’ll have yourself a 10-minute strength and cardio workout in one. Remember to use the handrail if needed and watch your feet, so you don’t trip.

Run up quickly using each step. Pump your arms next to your sides as you move quickly. Walk down the stairs carefully. Repeat. Strength: Walking LungeTime:Targets: 30 seconds Glutes, legs, core Start facing the bottom of the stairs. Step your right foot onto the next step and bend both knees as you lower into a lunge, keeping your front knee tracking over your shoe. Push off with your right foot and use your arms to help you propel your left foot onto the next step and lower into another lunge. Continue alternating legs until you reach the top of the stairs. Walk or jog down as usual. Repeat. Cardio: Sideways Stair RunTime: 30 seconds Start at the bottom of the stairs with your right side of the body closest to the stairs. Leading with your right foot, run up the stairs sideways. (Pretend your feet are chasing each other. Right foot goes first but as the left foot starts to approach the first step, the right foot should already be lifting to move up to the second step.) When you get to the top, walk down the stairs normally. Repeat. Strength: Push-UpsTime:Targets: 30 seconds Chest, arms, shoulders, core Place hands on first or second step with legs extended behind you on the ground so you’re in plank position. (The higher the step your hands are on, the easier the push-up will be.) Make sure your hands are shoulder-width apart. Bend elbows and slowly lower your chest down to the step. Exhale as you press your chest back up to starting position, keeping your core tight throughout. Repeat.
