I’ve been working on this combined skill all summer and I’ve made significant progress. I can now do it for a minute or more.
It still helps to throw the clubs narrow and high, rather than a broad pattern. I’m much better doing it with my right foot down than left foot, which reveals a strange body asymmetry. Actually, these things aren’t so strange, we all have asymmetries to some degree, we all have a preferred side which is interrelated to being right or left-handed. It’s also common for one leg or arm to be slightly longer than the other, but it’s usually not that noticeable.
It often takes doing “extreme” or unusual things to discover this.
Sheer exhaustion is what usually causes me to dismount, with my lower foot and leg getting increasingly sore. It’s much more tiring than juggling balls because clubs weigh more. And I still do drop sometimes before I reach exhaustion. I think it will take a little more time to become more efficient and not put so much pressure on my dominant foot. As my balance improves that means less energy expended trying to stay on the unicycle.
Hopefully the much cooler weather will make this less exhausting — juggling while unicycling sure generates a lot of heat!
