cant register arms that well while running??

Hello all... I seem to get the hang of most of the excersise and 9/10 register the moves at they should, but while running i allways being told to move my arms, and im really swinging away like a monkey with those arms, but nothing helps. Is there a certain way to swing those arms or what is the problem?? And i have tried to resync, dont help.|||Do you mean when it flashes it on the screen or just when the trainer tells you to move them? The trainers babble and endless stream of advice that has no relation to what you are doing. I get it sometimes when it flashes on the screen and I know what I'm doing so I just don't worry about it. I've learned with these games to not sweat the small stuff.|||dont think thats the problem.. on screen im running very slowly and sometimes fall behind and the trainer says to move my arms.. and it says so on screen to move my arms...|||Running I find is more about how high up you raise your legs. If you sort of just 'shuffle' around the leg sensor doesn't register and your avatar runs slowly. The more you raise your legs off the ground, the faster you tend to go.|||yeah it helps to raise knees instead of kicking them backwards,... it goes a lot better now
