Hi
I use a 25 and a 35 LB. Kb to anchor a 45 foot 1.5 inch rope. But that's because I had those kb already. It would be more practical to anchor them with the eye hook that they showed in minute of strength/website.
Thanks for the info! Since I posted this I saw on the Biggest Loser that it looked like they just had the rope wrapped around a post in the ground, so not attached to anything. I like the kettlebell idea except I don't have any that are that heavy. Where do you use your rope? I'm thinking I'll probably have to go out in the backyard to have more space. So is it a 45 ft rope doubled in 1/2 so you're holding 2 approximately 22 foot ropes?
Thanks again!
