I need to get back to jumping rope again
It’s solid cardio. Make sure that you get a long enough jump rope:
First, multiply your height (in feet) by two, ignoring the inches. Ex: 6ft whatever inches = 12 foot jump rope. Use this to determine the approximate length of the rope that you need. This gives you a place to start. If you can not size up the rope (because they’re all in packages) then someone on the lower end of six feet tall would look closer to the 10 feet length for their rope (ex 6ft 1 inch = 10 feet of jump rope). Someone at the middle end of 6ft would get the 12ft rope (6ft 3in tall).
If the ropes are out of the package or they have example ropes available then you can take the rope and step on the center of it. Fold it straight upward so that the ends of the handles goes to your arm pits, but not above. That should be your rope. Don’t get small handles, they’ll be uncomfortable to use.
Lastly, skip the super cheap ropes like Gold’s Gym. I know that it’s “just” a jump rope, but they will fall apart and you don’t want one end of the jump rope to go flying while you’re using it. Just some personal experience.
