Maybe you remember rope climbing from PE (or "Gym Class") in school. Maybe you did some as a kid just for fun, or as part of fitness training as an adult. It's good exercise, and can be good fun, too.
But what if you want to climb indoors and don't have a high ceiling? Or what if your upper body strength relative to your weight isn't so good? Never fear, a modification is here!
You'll need a thick rope for this. Sometimes they're knotted which makes the gripping part much easier but leaves a fixed distance for each step no matter your height or arm length. So no-knots is preferred. And there are other things you can do with a thick rope, so it's a nice tool to have.
Here's a quick video to show how you can do "rope climbs" with a low ceiling.
And just in case you're thinking of joining the army (in the 1980s):
"Incoming!" Classic.
Be seeing you.
