Walking 10,000 steps a day is a classic fat-loss move, but it can swallow more than 90 minutes.
In a recent YouTube video from the Built with Science team, three testers strapped on metabolic masks to hunt for faster alternatives.
Eleven exercises went head to head.
One option nearly tripled calorie burn for a tester.
Another, a $100 gadget beloved in many Asian households, barely beat standing still.
Which is which? Let’s dig in.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle

The Baseline: What 10,000 Steps Actually Burns
Testers wore masks measuring oxygen and carbon dioxide from every breath, far more accurate than a simple Apple Watch. Three people with different body types and fitness levels took part.
- Host: 418 calories
- Melody (similar weight): 438 calories
- Dennis (about 30 lbs lighter): 342 calories
Their data suggests a handy estimate: body weight in pounds multiplied by 2.7. Treat that as a ballpark drawn from just three people.
This is taking longer than I expected.
Every later exercise was ranked by how many minutes it takes to match that walking burn.
Winner #1: Incline Walking
Settings: 3 mph at a 9% incline for 20 minutes, no hands on the machine. Leaning back cancels out the incline, so cheating was banned.
- Host: 166 calories
- Dennis: 124 calories
- Melody: 252 calories
Host and Dennis burned at almost twice walking speed. Melody hit nearly triple.
Why? Inclines force big lower-body muscles like quads and glutes to work harder. Melody carries most of her muscle in her lower body, which may explain her lead.

Prediction equations suggest each 1% of incline lifts burn by roughly 10 to 15%.
It’s a lot of effort and for short legs, I feel like it’s just you really have to push yourself.
Winner #2: The StairMaster
Every step lifts body weight using huge muscles, and a set speed holds you accountable. Testers ran speed seven for 20 minutes.
- Host: 224 calories
- Melody: 300 calories
- Dennis: 136 calories
Melody’s heart rate climbed to 175 beats per minute, higher than during burpees. Dennis, meanwhile, leaned more body weight onto the machine every minute.
Holy crap, you are actually like working hard right now.
Short and Brutal: Burpees, Squats and Sprints
Burpees (10 minutes)
- Host: 100 reps, 128 calories
- Melody: 85 reps, 95 calories
- Dennis: 73 reps, 45 calories
Afterburn, measured by keeping masks on until heart rates recovered, added only about 10%. Dennis’ half-reps hurt his total.
Air Squats (10 minutes)
Paced at 30 squats per minute, the host burned 81 calories and Melody 78, nearly double walking speed. Dennis managed 29, slower than walking.
Squats have a bonus. A recent study cited in the video found that in people who sit all day, 10 squats every 45 minutes beat one 30-minute walk for controlling blood sugar after meals.

The host’s theory: leg muscles act like sponges, soaking up sugar from blood for energy.
Sprints (10 minutes)
Most of a sprint session is spent recovering. Totals including afterburn landed at 95 calories for the host, 61 for Dennis and 96 for Melody.
The Middle of the Pack: Rebounding, Rucking and Cycling
Rebounding on a mini trampoline is claimed online to burn 500 to 800 calories an hour. Real results fell well short: 62, 41 and 66 calories in 10 minutes.
Still, all three beat regular walking. Plus, it was undeniably fun.
Rucking means walking in a weighted vest or loaded backpack. A 20-lb vest over 20 minutes produced 108, 91 and 128 calories, only 20 to 30% faster than plain walking.
Worn through an entire 10,000-step day, that could add roughly 100 calories. Not nothing, but not a game changer.

Cycling at a self-selected pace for 20 minutes gave 130, 119 and 88 calories. With self-paced work, results depend on how hard you push.
The Disappointments
Japanese Interval Walking
The protocol alternates three minutes slow with three minutes fast for 30 minutes. Fast intervals are supposed to reach 70% of max heart rate, around 130 beats per minute for the host.
I can’t get my heart rate high enough.
Host and Dennis burned just 144 and 114 calories, still roughly 90 minutes to match walking. Melody got her heart rate high and burned 249, matching the walking baseline in 53 minutes instead of 91.
Metronome Marching
Take one light step per beat, stay on your toes and keep upright. Result: nearly one-for-one with walking, roughly 1,000 steps per 10 minutes.
Great news for TV time or indoor days, though not a shortcut.
Vibration Plate
Cranked to maximum, the $100 plate delivered 28, 22 and 33 calories in 10 minutes, only slightly above standing.

I was pretty confident the only thing it’s going to be burning is our money.
Research does exist. In one study, 35 women with obesity trained on a plate for 14 minutes twice weekly for 10 weeks, gaining leg strength and losing body fat compared with 15 non-exercising women.
But the host found that the plate’s manufacturer funded the study. With an inactive control group, it’s hard to credit the plate itself.
The Final Verdicts
- Dennis: incline walking, since he never cheated or complained
- Host: StairMaster, a staple in his garage
- Melody: StairMaster by the numbers, though she’d choose incline walking
Melody’s pick earned her a home treadmill from the host, and Dennis a one-on-one squat lesson.
I just don’t want people to take this literally and just not do any walking cuz I think it shows how like even plain old walking, it does burn calories and it’s very easy to do, right?
Practical Takeaways
- Short on time? Incline walking and stair climbing offered the biggest time savings.
- Keep hands off the rails. Leaning cancels much of the benefit.
- Stuck indoors? Metronome marching tracks regular walking closely.
- Sit all day? Brief squat breaks may help blood sugar.
- Skip the vibration plate if fat loss is the goal.
The best exercise is rarely the one that burns the most, but the one you can actually stick to.
