More power required, that little bit higher you have to jump and the greater degree of focus to get the double under is requiring/a display of - greater power.
I have been given the option of double unders for part of my GPP after lifting. I have never done them. I have just been doing some speed rope because I couldn't double unders on first attempt. Any reason why a double under is a significantly superior movement to just plain speed rope? I will work on learning to do the movement, I'm just not sure Ii see the advantage (which I may after I lean how.)
Thanks

Surely a double under is not purported to develop power!?
I can only see a double under as a conditioning tool.
Boxers use it to develop power, it may not be the most effective way to do so in the grand scheme of things. But the kind of repetitive powerful focused, light footed, hopping about involved in boxing mirrors double unders nicely. Boxers do not traditionally do any "leg work" (not saying this is the best way, but it is certainly the most common).
Exercises which demand concentrated power output are commonly used for conditioning purposes, for example all the olympic lifts in crossfit, kettbell swings or snatches, jumping, burpees etc...
Ugh, sounds like somebody is getting advice from a CrossFitter. Here's a hint: there's a lot more to jumping rope than double unders. Sure, double unders are one of the more taxing conditioning moves in jumping rope. But, seriously, just do a normal speed rope routine.
Double unders sure as hell do not develop power, nor to they provide any "leg work" from a strength perspective. Double unders are a conditioning exercise and will tire you out kind of quickly quickly, in part due to the extra demands placed on the shoulders. Spinning the rope at twice the speed fatigues your shoulders in ways that you might not expect at first. You are also doing your best to spend as much time in the air as you can and the minimum rope speed demanded by double unders is faster than the minimum speed for single unders. There is also a coordination component to double unders that you may or may not enjoy.
