We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Jump rope is part of our routine HIIT exercises. While I have learned the basic moves (singles, running man, jack jumps, split step jumps) I still can not get the hang of double unders and probably never will.
My cardio endurance with jumping is far from where I'd like it to be. That's partly because my technique is not as smooth and efficient as it could be, but part is my high intensity endurance.
I have tried 1 lb ropes several times, for a minute at a time. These things really kick your ass, partly because of the upper body demands.
