If you’ve spent any time on TikTok lately, you’ve probably seen the buzz around the 25-7-2 StairMaster workout. It’s quickly “stepping” into the spotlight, giving the once-viral 12-3-30 treadmill routine a run for its money.
If you use the StairMaster at the gym (or are lucky enough to have one at home), you know these things are no joke. What looks like such a simple piece of cardio equipment will completely fry your lower body in no time.
The 25-7-2 StairMaster workout sticks to a single machine, much like its treadmill predecessor. That simplicity is part of the appeal. It’s accessible, easy to understand, and doesn’t require a complicated setup.
I’ll be honest, the first time I tried it, I underestimated it. The StairMaster has a way of humbling you quickly, especially if you’re used to cruising on a treadmill or pedaling away on a recumbent bike.
But in this article, I’m going to dive deeper into the 25-7-2 StairMaster workout and help you understand what it is and if it’s something you should try to change up your boring cardio routine.

What is the 25-7-2 StairMaster Workout?
If you’ve never tried the StairMaster (the cardio machine designed to replicate climbing stairs), you might be overlooking one of the most demanding sweat sessions in the gym. It may look simple at first glance, but it challenges both your endurance and strength in a steady, no-frills way.
I used to think the StairMaster was only for women, as you rarely ever find a man stepping away on one. But then I tried it and let me tell you… it will kick your ass.
The StairMaster is often described as somewhat of a low-impact workout, yet it still delivers great results. It supports cardiovascular health while strengthening the quads, core, and calves.
That said, low impact does not mean low effort. Once you’re a few minutes in, you’ll understand that quickly as you feel your lower body muscles start to burn.
As for the 25-7-2 StairMaster workout, the structure is simple. You climb for 25 minutes at level seven and repeat the workout twice a week.
To make it even more effective, go hands-free and avoid holding onto the rails, which keeps your core engaged throughout the entire 25-minute cardio session.
4 Benefits of the 25-7-2 StairMaster Workout
Below are some of the benefits of the 25-7-2 StairMaster workout:
1. Increases mobility
One reason the StairMaster stands out is that it boosts natural movement patterns. Climbing engages the way your body is meant to move, especially through proper hip extension and steady, upright motion.
When building out an aerobic routine, many trainers look for exercises that support functional movements. As a strength coach, I can confirm that we are seeing a massive shift to functional training and functional movements.
The goal isn’t just to get your heart rate up, but to choose movements that translate well into everyday strength and mobility.
2. It is a low-risk workout
One reason the 25-7-2 StairMaster trend is gaining popularity is that it’s fairly low risk. The movement is simple, and most fitness levels can handle it as long as you can maintain a steady footing for a continuous 25 minutes.
It’s also low impact. Like walking, it doesn’t put as much stress on your joints as running does, making it easier on your knees, hips, ankles, and overall joints.
That said, if you have existing knee or lower back issues, it would be a good idea to talk with your doctor to see if he recommends you jumping on a StairMaster.
The stair-climbing motion can also help strengthen the muscles around the knees, which may support certain weaknesses when done correctly.
3. Improves core strength, coordination, and balance
Long-term fitness isn’t just about endurance or strength alone. It’s about improving multiple areas at once, from balance to muscle control. That’s where the 25-7-2 StairMaster becomes more important. It is a mix of cardio and strength in a single session, while also forcing you to stay steady as you climb.
Stair climbing naturally challenges your balance. Your core and hip flexors have to stay engaged to control each step. When you take your hands off the rails, that challenge increases, and your core has to work even harder to stabilize you.
4. It builds endurance
Zone 2 training, which means working at about 60%-70% of your maximum heart rate, is often linked to better longevity, fewer injuries, and improved overall performance. It also helps with body composition and reduces the risk of overtraining.
A 2021 study compared moderate workouts done five times a week with a HIIT routine performed three times weekly. The results showed that only the moderate-intensity group experienced reductions in body fat and blood pressure.
These are key markers tied to heart health, and they did not improve in the HIIT group.
Tips for the 25-7-2 StairMaster Workout
1. Warm up and cool down
Before getting started, activate your glutes and core with moves like hip bridges, planks, or dead bugs.
After your session, stretch your glutes, hamstrings, and calves. Pigeon pose and downward dog work well.
2. Maintain proper form
Stay upright and avoid leaning on the handrails. Keep your chest lifted so you can breathe properly, and make sure your shoulders stay stacked over your hips.
3. Add strength training
While the 25-7-2 StairMaster workout is done twice a week, balance it with strength training. It helps build bone density and muscular endurance.
Since the StairMaster moves in one direction, include exercises that challenge your body in different planes of motion.
