Kick Backs

Everytime I do the fast kickbacks it says I am going too slow. I notice if I take the nunchuck out of the leg strap it reads them fine....anyone else have this issue? I think it is a bug. :)|||Move the leg strap higher up on your leg. I can get the kickbacks to register if I'm doing a high knee run - I am working up to 2 laps of high kickbacks. So far I can only do one before I want to die. lol|||I hold the nunchuck and remote in my hand and it works better.
