Which one burns more calories?

Running on a treadmill or skipping rope?
Treadmill = 400Calories/20mins
SkipRope = 1200Calories/20mins
^ I was told.Which one burns more calories?
okay i would say jumproping because ure adjectives body is constitly moving when you are doing this. i would also reccomend the treadmill though because it does not tire u *** much.
jumproping definately!
skipping rope burns more calories but running is less tiring
Skipping rope doesn't burn that oodles calories.
Also, running on a treadmill doesn't burn 400 calories in 20 minutes unless you are at a maximum incline and speed.
You will not burn 400 calories on the treadmill for 20 minutes. Average is nearly 200-300 on the treadmill for 20 minutes unless you're sprinting for all of those minutes.
both numbers appear really overstated. treadmill - around 600 - 800 calories per hour. skipping rope - probably more, but not 3 times more!
