Incline beats speed for calorie burn
Walking faster gets uncomfortable quickly, but adding grade raises energy cost sharply while staying joint-friendly. A 10% incline at 3 mph roughly doubles flat-ground burn, which is why weighted incline walking has become the default low-impact conditioning tool.
- • Do not hold the treadmill handrails — it cuts the real cost by 20–25%.
- • A weighted pack adds burn in direct proportion to total mass carried.
- • Downhill walking burns less but loads the knees eccentrically.
FAQ
How many calories does a 30-minute walk burn?
For a 175 lb person at 3.2 mph on flat ground, roughly 150–180 calories gross and about 120–140 net.
Does walking uphill burn more calories?
Substantially. Each 1% of grade adds roughly 8–12% to energy cost at typical walking speeds.
Is walking or running better for weight loss?
Running burns more per minute, walking is easier to sustain daily and provokes less compensatory eating. The best option is the one you will keep doing.
