OMG I can't believe these idiots! Of course it is going to take the same amount of energy to "climb" on this treadmill apparatus as it does to walk. It will take more energy to actually climb up something that it will to climb on this apparatus. When actually climbing, potential energy is being increased, requiring work to be done. When on this apparatus, there is no potential energy gain, therefore no work being done. The only work being done is in the movement of the animal's body parts, just the same as walking. I can't believe these idiots call themselves scientists.

Am I missing something?
