Straight up and down hopping is all I do although sometimes compensation is
required. I consider myself a master hopper and have hopped 12hrs straight…
Hop up stairs, down, in circles and down the street… hehe! I learned the pogo
stick before a uni so it came very easy to hop on a uni. Skill level about the
one hand… bla bla bla… It depends on how you want to hop… If hopping up
stairs, good luck with one hand. I use 2 hands (one in front and one in back)
