So, a standard, high line is actually a pretty simple thing. Imagine you're playing jump rope with your friends. You hold the rope and swing it around while your friends try to jump over it.
Now, imagine you and your friends want to do something a little fancier. Instead of just jumping over the rope, you want to jump over it while also doing a spin or a twirl. That's where a standard, high line comes in.
Instead of holding the rope at waist height like you normally would, you hold it up high above your head. This gives you and your friends more room to jump and do cool tricks. It also makes the jumps a little bit harder, because you have to jump higher to clear the rope.
So, a standard, high line is just a fancy way of holding the jump rope up high so you can do cooler tricks with it. Pretty simple, right?
