One controller limitations?

I was trying to get excited for the just dance experience but when I realised it only uses one controller per player I realised I could flub the points by sitting down and doing the bare min of movement and still get 4-5 stars each song.

I looked around and saw stuff talking about the controller imagining the skeleton but with only one controller there seems no point asking for opposite hand movements or leg moments when it's just tracking the one controller that still thinks it's doing all the things while sitting and bored.

So I look to the community to see positive ways you managed to get the experience of using both controllers without needing to have a second player included.

PS: For some reason I was expecting a full body tracking to prevent me from giving min effort, much like how the sing games need to catch people humming to stop them exploiting the max score with soft humming.
