I'm with you. When I was 120 lbs and a pretty fast runner, the most I could do at 10mph on the treadmill was 1 min. And I was hauling!!!! Maybe she was telling them to do 12 min. miles- you know- 5 mph?
I don't think they can do it. I'm not saying never- just not for one minute. And even if they could- that would seem to be a bit too much stress to put on their bodies I would think.
I think lots of things they do on that show are a bit over-the-top. I've never been a huge fan of the show in general, tho, so I might not be the best person to give my opinion.![]()
