How many calories do you burn when speed walking 1 mile for 40 minutes?
3 miles per hour is needed to lose weight! You should've done 2 miles in 40 minutes!I'm over 50 & can walk 3 miles per hour! You can do it!!
It depends on how much you weight, whether or not you are going uphill, downhill, over even terrain, how cold it is, etc...
Depends on how fast you're walking.
1 mile in 40 minutes? doesn't sound like 'speed walking' to me. Faster! Burns more calories. About... 100-120 calories.
